title: Structure of exotic nuclei around double shell closures

abstract:
  In this paper, we first give a brief review of the theoretical framework for
microscopic shell-model calculations starting from the free nucleon-nucleon
potential. In this context, we discuss the use of the low-momentum
nucleon-nucleon interaction V-low-k in the derivation of the shell-model
effective interaction and emphasize its practical value as an alternative to
the Brueckner G-matrix method. Then, we present some results of our current
study of exotic nuclei around doubly magic 132Sn, which have been obtained
starting from the CD-Bonn potential renormalized by use of the V-low-k
approach. Attention is focused on the nuclei 134Te, 134Sn, and 136Te, in
particular on the latter which is a direct source of information on the
proton-neutron effective interaction in the 132Sn region. Comparison shows that
our results are in very good agreement with the available experimental data.


title:
Analysis of the quadrupole deformation of $\Delta$(1232) within an
  effective Lagrangian model for pion photoproduction from the nucleon

abstract:
  We present an extraction of the E2/M1 ratio of the $\Delta$(1232) from
experimental data applying an effective Lagrangian model. We compare the result
obtained with different nucleonic models and we reconcile the experimental
results with the Lattice QCD calculations.


title: Dynamic Time Scales in Colored Glass Nuclear Matter

abstract:
  In Ultra high energy collisions, the concept of a glass law is invoked in the
framework of 'low tension' QCD strings. It is shown that the excitation of QCD
strings at low energy has a negative temperature and at high energy has a
positive temperature always higher than the Hagedorn temperature, T_H. Very
high energy strings T->T_H + 0+ move very slowly as a viscous melted glass with
very high viscosity. However, in a very short collision time, it is difficult
to transfer the initial collision kinetic energy into the internal energy of a
few strings. The low energy strings at high T>>T_H have a low viscosity giving
rise to an almost perfect fluid. The role of strings in a nucleus is closely
analogous to the role of polymer chains in some viscous glass beads.


title: Coexistence of BCS and BEC-like pair structures in halo nuclei

abstract:
  We investigate the spatial structure of the two-neutron wave function in the
Borromean nucleus $^{11}$Li, using a three-body model of $^9$Li $+n+n$, which
includes many-body correlations stemming from the Pauli principle. The behavior
of the neutron pair at different densities is simulated by calculating the
two-neutron wave function at several distances between the core nucleus $^9$Li
and the center of mass of the two neutrons. With this representation, a strong
concentration of the neutron pair on the nuclear surface is for the first time
quantitatively established for neutron-rich nuclei. That is, the neutron pair
wave function in $^{11}$Li has an oscillatory behavior at normal density, while
it becomes a well localized single peak in the dilute density region around the
nuclear surface. We point out that these features qualitatively correspond to
the BCS and BEC-like structures of the pair wave function found in infinite
nuclear matter.


title:
Properties of few-body systems in relativistic quantum mechanics and
  constraints from transformations under Poincar\'{e} space-time translations

abstract:
  Different approaches have been applied to the calculation of form factors of
various hadronic systems within relativistic quantum mechanics. In a one-body
current approximation, they can lead to results evidencing large discrepancies.
Looking for an explanation of this spreading, it is shown that, for the largest
part, these discrepancies can be related to a violation of Poincar\'e
space-time translation invariance. Beyond energy-momentum conservation, which
is generally assumed, fulfilling this symmetry implies specific relations that
are generally ignored. Their relevance within the present context is discussed
in detail both to explain the differences between predictions and to remove
them.


title: Neutron-proton mass difference in nuclear matter

abstract:
  Isospin-breaking effects in nuclear matter are studied in the framework of a
medium-modified Skyrme model. The proposed effective Lagrangian incorporates
both the medium influence of the surrounding nuclear environment on the single
nucleon properties and an explicit isospin-breaking effect in the mesonic
sector. The approach predicts that the neutron-proton mass difference decreases
in isospin-symmetric nuclear matter but by a very small amount only.


title: Coulomb sum rule in quasielastic region

abstract:
  Within a relativistic single particle model, we calculate the Coulomb sum
rule of inclusive electron scattering from $^{40}$Ca and $^{208}$Pb in
quasielastic region. Theoretical longitudinal and transverse structure
functions are extracted for three momentum transfers from 300 to 500 MeV/c and
compared with the experimental data measured at Bates and Saclay. We find that
there is no drastic suppression of the longitudinal structure function and that
the Coulomb sum rule depends on nucleus in our theoretical model.


title: Coulomb force effects in low-energy $\alpha$-deuteron scattering

abstract:
  The $\alpha$-proton Coulomb interaction is included in the description of
$\alpha$-deuteron scattering using the screening and renormalization approach
in the framework of momentum-space three-particle equations. The technical
reliability of the method is demonstrated. Large Coulomb-force effects are
found.


title: pT-fluctuations and multiparticle clusters in heavy-ion collisions

abstract:
  We investigate the centrality dependence of the pT-correlations in the
event-by-event analysis of relativistic heavy-ion collisions at RHIC made
recently by the PHENIX and STAR Collaborations. We notice that sigma^2
dynamical scales to a very good accuracy with the inverse number of the
produced particles, n. This scaling can be naturally explained by formation of
clusters. We discuss the nature of clusters and provide numerical estimates of
correlations coming from resonance decays, which are tiny, and a model where
particle are emitted from local thermalized sources moving at the same
collective velocity. This "lumped cluster" model can explain the data when on
the average 6-15 particles are contained in a cluster. We also point out simple
relations of the popular correlation measures to the covariance, which arise
under the assumptions (well holding at RHIC) that the distributions are sharply
peaked in n and that the dynamical compared to statistical fluctuations are
small.


title: The neutron matter equation of state from low-momentum interactions

abstract:
  We calculate the neutron matter equation of state at finite temperature based
on low-momentum nucleon-nucleon and three-nucleon interactions. Our results are
compared to the model-independent virial equation of state and to variational
calculations. We provide a simple estimate for the theoretical error, important
for extrapolations to astrophysical conditions.


title: Mean Field Effects In The Quark-Gluon Plasma

abstract:
  A transport model based on the mean free path approach for an interacting
meson system at finite temperatures is discussed. A transition to a quark gluon
plasma is included within the framework of the MIT bag model. The results
obtained compare very well with Lattice QCD calculations when we include a mean
field in the QGP phase due to the Debye color screening. In particular the
cross over to the QGP at about 175 MeV temperature is nicely reproduced. We
also discuss a possible scenario for hadronization which is especially
important for temperatures below the QGP phase transition.


title: Microscopic Determinations of Fission Barriers, (MEAN-Field and Beyond)

abstract:
  With a help of the selfconsistent Hartree-Fock-Bogoliubov (HFB) approach with
the D1S effective Gogny interaction and the Generator Coordinate Method (GCM)
we incorporate the transverse collective vibrations to the one-dimensional
model of the fission-barrier penetrability based on the traditional WKB method.
The average fission barrier corresponding to the least-energy path in the
two-dimensional potential energy landscape as function of quadrupole and
octupole degrees of freedom is modified by the influence of the transverse
collective vibrations along the nuclear path to fission. The set of transverse
vibrational states built in the fission valley corresponding to a successively
increasing nuclear elongation produces the new energy barrier which is compared
with the least-energy barrier. These collective states are given as the
eigensolutions of the GCM purely vibrational Hamiltonian. In addition, the
influence of the collective inertia on the fission properties is displayed, and
it turns out to be the decisive condition for the possible transitions between
different fission valleys.


title:
Bound Electron Screening Corrections to Reactions in Hydrogen Burning
  Processes

abstract:
  How important would be a precise assessment of the electron screening effect,
on determining the bare astrophysical $S$-factor ($S_b(E)$) from experimental
data? We compare the $S_b(E)$ obtained using different screening potentials,
(1) in the adiabatic limit, (2) without screening corrections, and (3) larger
than the adiabatic screening potential in the PP-chain reactions. We employ two
kinds of fitting procedures: the first is by the conventional polynomial
expression and the second includes explicitly the contribution of the nuclear
interaction and based on a statistical model.
  Comparing bare $S$-factors that are obtained by using different screening
potentials, all $S_b(E)$ are found to be in accord within the standard errors
for most of reactions investigated, as long as the same fitting procedure is
employed. $S_b(E)$ is, practically, insensitive to the magnitude of the
screening potential.


title:
Nucleon Polarisabilities from Deuteron Compton Scattering, and Its
  Lessons for Chiral Power Counting

abstract:
  A brief review of Compton scattering off the deuteron in Chiral Effective
Field Theory, including gauge invariance and the correct Thomson limit. We
model-independently determine the iso-scalar, spin-independent dipole
polarisabilities of the nucleon at zero energy from all Compton data below 100
MeV as \alpha_{E1}^s=11.3+-0.7_{stat}\+-0.6_{Baldin}+-1_{theory},
\beta_{M1}^s=3.2-+0.7_{stat}+-0.6_{Baldin}+-1_{theory}, each in 10^{-4} fm^3.
Proton and neutron polarisabilities are therefore identical within
(predominantly statistical) errors.


title:
Multiplicity fluctuations in relativistic nuclear collisions:
  statistical model versus experimental data

abstract:
  The multiplicity distributions of hadrons produced in central nucleus-nucleus
collisions are studied within the hadron-resonance gas model in the large
volume limit. The microscopic correlator method is used to enforce conservation
of three charges - baryon number, electric charge, and strangeness - in the
canonical ensemble. In addition, in the micro-canonical ensemble energy
conservation is included. An analytical method is used to account for resonance
decays. The multiplicity distributions and the scaled variances for negatively,
positively, and all charged hadrons are calculated along the chemical
freeze-out line of central Pb+Pb (Au+Au) collisions from SIS to LHC energies.
Predictions obtained within different statistical ensembles are compared with
the preliminary NA49 experimental results on central Pb+Pb collisions in the
SPS energy range. The measured fluctuations are significantly narrower than the
Poisson ones and clearly favor expectations for the micro-canonical ensemble.
Thus this is a first observation of the recently predicted suppression of the
multiplicity fluctuations in relativistic gases in the thermodynamical limit
due to conservation laws.


title: Pairing properties of superheavy nuclei

abstract:
  Pairing properties of even-even superheavy N=184 isotones are studied within
the Skyrme-Hartree-Fock+BCS approach. In the particle-hole channel we take the
Skyrme energy density functional SLy4, while in the particle-particle channel
we employ the seniority pairing force and zero-range delta-interactions with
different forms of density dependence. We conclude that the calculated static
fission trajectories weakly depend on the specific form of the delta-pairing
interaction. We also investigate the impact of triaxiality on the inner fission
barrier and find a rather strong Z dependence of the effect.


title: Nuclear Physics with Electroweak Probes

abstract:
  The research activitities carried out in Italy during the last two years in
the field of theoretical nuclear physics with electroweak probes are reviewed.
Different models for electron-nucleus and neutrino-nucleus scattering are
compared. The results obtained for electromagnetic reactions on few-nucleon
systems and on complex nuclei are discussed. The recent developments in the
study of electron- and photon-induced reactions with one and two-nucleon
emission are presented.


title: Modern compact star observations and the quark matter EoS

abstract:
  A hybrid equation of state for dense matter is presented that satisfies
phenomenological constraints from modern compact star observations which
indicate high maximum masses of about 2 M_sun and large radii of R> 12 km. The
corresponding isospin symmetric equation of state is consistent with flow data
analyses of heavy-ion collisions. The transition from nuclear to two-flavor
color superconducting quark matter at n approximately 0.55 fm^{-3} is almost a
crossover.


title:
Microscopic calculations of double and triple Giant Resonance excitation
  in heavy ion collisions

abstract:
  We perform microscopic calculations of the inelastic cross sections for the
double and triple excitation of giant resonances induced by heavy ion probes
within a semicalssical coupled channels formalism. The channels are defined as
eigenstates of a bosonic quartic Hamiltonian constructed in terms of collective
RPA phonons. Therefore, they are superpositions of several multiphonon states,
also with different numbers of phonons and the spectrum is anharmonic. The
inclusion of (n+1) phonon configurations affects the states whose main
component is a n-phonon one and leads to an appreacible lowering of their
energies. We check the effects of such further anharmonicities on the previous
published results for the cross section for the double excitation of Giant
Resonances. We find that the only effect is a shift of the peaks towards lower
energies, the double GR cross section being not modified by the explicity
inclusion of the three-phonon channels in the dynamical calculations. The
latters give an important contribution to the cross section in the triple GR
energy region which however is still smaller than the experimental available
data. The inclusion of four phonon configurations in the structure calculations
does not modify the results.


title:
Semiclassical Distorted Wave Model Analysis of the $(\pi^-,K^+)$
  $\Sigma$ Formation Inclusive Spectrum

abstract:
  $(\pi^-,K^+)$ hyperon production inclusive spectra with $p_\pi =1.2$ GeV/c
measured at KEK on $^{12}$C and $^{28}$Si are analyzed by the semiclassical
distorted wave model. Single-particle wave functions of the target nucleus are
treated using Wigner transformation. This method is able to account for the
energy and angular dependences of the elementary process in nuclear medium
without introducing the factorization approximation frequently employed.
Calculations of the $(\pi^+,K^+)$ $\Lambda$ formation process, for which there
is no free parameter since the $\Lambda$ s.p. potential is known, demonstrate
that the present model is useful to describe inclusive spectra. It is shown
that in order to account for the experimental data of the $\Sigma^-$ formation
spectra a repulsive $\Sigma$-nucleus potential is necessary whose magnitude is
not so strong as around 100 MeV previously suggested.


title: Application of chiral nuclear forces to light nuclei

abstract:
  In these proceedings, we discuss the current status of nuclear bound state
predictions based on chiral nuclear interactions. Results of ordinary $s$- and
$p$-shell nuclei and light hypernuclei are shown.


title:
The baryon-decuplet in the chiral dynamics of Lambda-hyperons in nuclear
  matter

abstract:
  We study the long range part of the $\Lambda$-hyperon optical potential in
nuclei using Quantum Many Body techniques and flavor-SU(3) Chiral Lagrangians
as starting point. More precisely, we study the contributions to the
$\Lambda$-hyperon optical potential due to the long-range two-pion exchange,
with $\Sigma$ and $\Sigma^*$ baryons in the internal baryonic lines and
considering Nh and $\Delta$h excitations. We also consider the contribution to
the spin-orbit potentials that comes out from these terms. Our results support
a natural explanation of the smallness of the $\Lambda$-nuclear spin-orbit
interaction and shows the importance of the $\Sigma^*$ and $\Delta$ degrees of
freedom for the hyperon-nucleus interactions.


title:
Axial, induced pseudoscalar, and pion-nucleon form factors in manifestly
  Lorentz-invariant chiral perturbation theory

abstract:
  We calculate the nucleon form factors G_A and G_P of the isovector
axial-vector current and the pion-nucleon form factor G_piN in manifestly
Lorentz-invariant baryon chiral perturbation theory up to and including order
O(p^4). In addition to the standard treatment including the nucleon and pions,
we also consider the axial-vector meson a_1 as an explicit degree of freedom.
This is achieved by using the reformulated infrared renormalization scheme. We
find that the inclusion of the axial-vector meson effectively results in one
additional low-energy coupling constant that we determine by a fit to the data
for G_A. The inclusion of the axial-vector meson results in an improved
description of the experimental data for G_A, while the contribution to G_P is
small.


title: Working Group Summary: Chiral Dynamics in Few-Nucleon Systems

abstract:
  We summarize the findings of our Working Group, which discussed progress in
the understanding of Chiral Dynamics in the A=2, 3, and 4 systems over the last
three years. We also identify key unresolved theoretical and experimental
questions in this field.


title: Heavy ion collisions in the used nucleon model

abstract:
  It is shown that recently proposed by R.J. Glauber the used nucleon model
combined with the assumption that the nucleon consists of two constituents (a
quark and a diquark) describes well the PHOBOS data on particle production at
midrapidity.


title: Treatment of the Coulomb interaction in three-nucleon reactions

abstract:
  The Coulomb interaction between the two protons is included in the
calculation of three-nucleon hadronic and electromagnetic reactions using
screening and renormalization approach. Calculations are done using integral
equations in momentum space. The reliability of the method is demonstrated. The
Coulomb effect on observables is discussed.


title:
Lattice Simulations for Light Nuclei: Chiral Effective Field Theory at
  Leading Order

abstract:
  We discuss lattice simulations of light nuclei at leading order in chiral
effective field theory. Using lattice pion fields and auxiliary fields, we
include the physics of instantaneous one-pion exchange and the leading-order
S-wave contact interactions. We also consider higher-derivative contact
interactions which adjust the S-wave scattering amplitude at higher momenta. By
construction our lattice path integral is positive definite in the limit of
exact Wigner SU(4) symmetry for any even number of nucleons. This SU(4)
positivity and the approximate SU(4) symmetry of the low-energy interactions
play an important role in suppressing sign and phase oscillations in Monte
Carlo simulations. We assess the computational scaling of the lattice algorithm
for light nuclei with up to eight nucleons and analyze in detail calculations
of the deuteron, triton, and helium-4.


title: Final State Distortions in Two-Particle Correlations

abstract:
  Final state interactions in two-particle interferometry is considered for
two-particle potentials which are the Coulomb plus "strong" one. For a simple
model of the source we provide a full numerical calculation of the correlation
function with taking into account two-particle Coulomb interaction plus final
state strong interaction. It is found that for small sources (R=1-4 fm) the
contribution from the strong interaction is appreciable and depresses the
correlations while for large fireballs (R=7-10 fm) this contribution is small
in comparison to the Coulomb one.


title:
Global study of the spectroscopic properties of the first 2+ state in
  even-even nuclei

abstract:
  We discuss the systematics of the 2+ excitation energy and the transition
probability from this 2+ to the ground state for most of the even-even nuclei,
from O16 up to the actinides, for which data are available. To that aim we
calculate their correlated J=0 ground state and J=2 first excited state by
means of the angular-momentum and particle-number projected generator
coordinate method, using the axial mass quadrupole moment as the generator
coordinate and self-consistent mean-field states only restricted by axial,
parity, and time-reversal symmetries. The calculation, which is an extension of
a previous systematic calculation of correlations in the ground state, is
performed within the framework of a non-relativistic self-consistent mean-field
model using the same Skyrme interaction SLy4 and a density-dependent pairing
force to generate the mean-field configurations and mix them.


title:
Relativistic Dynamics of Non-ideal Fluids: Viscous and heat-conducting
  fluids I. General Aspects and 3+1 Formulation for Nuclear Collisions

abstract:
  Relativistic non-ideal fluid dynamics is formulated in 3+1 space--time
dimensions. The equations governing dissipative relativistic hydrodynamics are
given in terms of the time and the 3-space quantities which correspond to those
familiar from non-relativistic physics. Dissipation is accounted for by
applying the causal theory of relativistic dissipative fluid dynamics. As a
special case we consider a fluid without viscous/heat couplings in the causal
system of transport/relaxation equations. For the study of physical systems we
consider pure (1+1)-dimensional expansion in planar geometry, (1+1)-dimensional
spherically symmetric ({\em fireball}) expansion, (1+1)-dimensional
cylindrically symmetric expansion and a (2+1)-dimensional expansion with
cylindrical symmetry in the transverse plane ({\em firebarell} expansion). The
transport/relaxation equations are given in terms of the spatial components of
the dissipative fluxes, since these are not independent. The choice for the
independent components is analogous to the non-relativistic equations.


title:
Relativistic Dynamics of Non-ideal Fluids: Viscous and heat-conducting
  fluids II. Transport properties and microscopic description of relativistic
  nuclear matter

abstract:
  In the causal theory of relativistic dissipative fluid dynamics, there are
conditions on the equation of state and other thermodynamic properties such as
the second-order coefficients of a fluid that need to be satisfied to guarantee
that the fluid perturbations propagate causally and obey hyperbolic equations.
The second-order coefficients in the causal theory, which are the relaxation
times for the dissipative degrees of freedom and coupling constants between
different forms of dissipation (relaxation lengths), are presented for partonic
and hadronic systems. These coefficients involves relativistic thermodynamic
integrals. The integrals are presented for general case and also for different
regimes in the temperature--chemical potential plane. It is shown that for a
given equation of state these second-order coefficients are not additional
parameters but they are determined by the equation of state. We also present
the prescription on the calculation of the freeze-out particle spectra from the
dynamics of relativistic non-ideal fluids.


title:
A new class of quantum bound states: diprotons in extreme magnetic
  fields

abstract:
  This paper considers the possibility that two charged particles with an
attractive short-ranged potential between them which is not strong enough to
form bound states in free space, may bind in uniform magnetic fields. It is
shown that in the formal limit where Coulomb repulsion is negligible (q -> 0
and B_0 -> \infty with q B_0 fixed where q is the charge and B_0 the field
strength) there always exists a bound state for a system of two identical
charged particles in a constant magnetic field, provided that there is a
short-range uniformly attractive potential between them. Moreover, it is shown
that in this limit {\it any} potential with an attractive s-wave scattering
length will posses bound states provided that the range of the potential is
much smaller than the characteristic magnetic length, r_0 = (\frac{q
B_0}{4})^{-1/2}. For this case, the binding is computed numerically. We
estimate the size of the magnetic field needed to approximately reach a regime
where the formal limit considered becomes a good approximation to the dynamics.
These numerical estimates indicate that two protons in an extremely strong
magnetic field such as might be found in a magnetar will bind to form a
diproton.


title: Rapidity Dependence of HBT radii based on a hydrodynamical model

abstract:
  We calculate two-pion correlation functions at finite rapidities based on a
hydrodynamical model which does not assume explicit boost invariance along the
collision axis. Extracting the HBT radii through $\chi^2$ fits in both
Cartesian and Yano-Koonin-Podgoretski\u{\i} parametrizations, we compare them
with the experimental results obtained by the PHOBOS. Based on the results, we
discuss longitudinal expansion dynamics.


title: Dynamical Freeze-out in 3-Fluid Hydrodynamics

abstract:
  Freeze-out procedure accepted in the model of 3-fluid dynamics (3FD) is
analyzed. This procedure is formulated in terms of drain terms in hydrodynamic
equations. Dynamics of the freeze-out is illustrated by 1-dimensional
simulations. It is demonstrated that the resulting freeze-out reveals a
nontrivial dynamics depending on initial conditions in the expanding
``fireball''. The freeze-out front is not defined just ``geometrically'' on the
condition of the freeze-out criterion met but rather is a subject the fluid
evolution. It competes with the fluid flow and not always reaches the place
where the freeze-out criterion is met. Dynamics of the freeze-out in 3D
simulations is analyzed. It is demonstrated that the late stage of central
nuclear collisions at top SPS energies is of the form of three (two baryon-rich
and one baryon-free) fireballs separated from each other.


title: Partial-wave analysis of $K^+$ nucleon scattering

abstract:
  We have performed a partial-wave analysis of K$^+$-nucleon scattering in the
momentum range from 0 to 1.5 GeV/c addressing the uncertainties of the results
and comparing them with several previous analyses. It is found that the
treatment of the reaction threshold behavior is particularly important. We find
a T=0 scattering length which is not consistent with zero, as has been claimed
by other analyses. The T=0 phase shifts for $\ell>0$ are consistent with a pure
spin-orbit potential. Some indications for the production of a T=0 pentaquark
with spin-parity D5/2+ are discussed.


title: Nuclear Force from Lattice QCD

abstract:
  Nucleon-nucleon (NN) potential is studied by lattice QCD simulations in the
quenched approximation, using the plaquette gauge action and the Wilson quark
action on a 32^4 (\simeq (4.4 fm)^4) lattice. A NN potential V_{NN}(r) is
defined from the equal-time Bethe-Salpeter amplitude with a local interpolating
operator for the nucleon. By studying the NN interaction in the ^1S_0 and ^3S_1
channels, we show that the central part of V_{NN}(r) has a strong repulsive
core of a few hundred MeV at short distances (r \alt 0.5 fm) surrounded by an
attractive well at medium and long distances. These features are consistent
with the known phenomenological features of the nuclear force.


title: Relativistic BCS-BEC crossover in a boson-fermion model

abstract:
  We investigate the crossover from Bardeen-Cooper-Schrieffer (BCS) pairing to
a Bose-Einstein condensate (BEC) in a relativistic superfluid within a
boson-fermion model. The model includes, besides the fermions, separate bosonic
degrees of freedom, accounting for the bosonic nature of the Cooper pairs. The
crossover is realized by tuning the difference between the boson mass and boson
chemical potential as a free parameter. The model yields populations of
condensed and uncondensed bosons as well as gapped and ungapped fermions
throughout the crossover region for arbitrary temperatures. Moreover, we
observe the appearance of antiparticles for sufficiently large values of the
crossover parameter. As an application, we study pairing of fermions with
imbalanced populations. The model can potentially be applied to color
superconductivity in dense quark matter at strong couplings.


title: Critical review of deeply bound kaonic nuclear states

abstract:
  We critically revise the recent claims of narrow deeply bound kaonic states
and show that at present there is no convincing experimental evidence for their
existence. In particular, we discuss in details the claim of K- pp deeply bound
state associated to a peak seen in the Lambda p invariant mass spectrum from K-
nuclear absorption reactions by the FINUDA collaboration. An explicit
theoretical simulation shows that the peak is simply generated from a
two-nucleon absorption process, like K- pp --> Lambda p, followed by
final-state interactions of the produced particles with the residual nucleus.


title: Renormalization of Singular Potentials and Power Counting

abstract:
  We analyze the renormalization of the nucleon--nucleon interaction at low
energies in coordinate space for both one and two pion exchange chiral
potentials. The singularity structure of the long range potential and the
requirement of orthogonality respectively determines, once renormalizability is
imposed, the minimum and maximum number of counterterms allowed in the
effective description of the nucleon--nucleon interaction in a non-perturbative
context.


title:
The position of the quasielastic peak and electron Coulomb distortion in
  (e,e') scattering

abstract:
  The position of the quasielastic peak for (e,e') scattering off 208-Pb
extracted from a selected data set measured at Saclay is related to a heuristic
theoretical description. An analysis of the data shows that the peak position
can be described very accurately by a simple equation in the relevant kinematic
region where a pronounced peak is observable. The simple findings result in a
concluding comment related to recent calculations concerning the Coulomb
distortion in (e,e') scattering for heavy nuclei.


title: On the sign of the pi-rho-omega coupling constant

abstract:
  It is shown that the relative sign between the $NN\omega$ and $\pi\rho\omega$
coupling constants can be determined most sensitively from $\omega$ production
processes in $NN$ collisions. Recent data on these reactions clearly favor the
sign of the $\pi\rho\omega$ coupling constant which is opposite to that
inferred from studies of the photoproduction reaction in combination with the
vector meson dominance assumption and used by many authors. Implication of this
finding in the description of other reactions is discussed.


title: The Van-der-Waals Gas EOS for the Lorentz Contracted Spheres

abstract:
  The relativistic equation of state (EOS) of the Van-der-Waals gas is
suggested and analyzed. In contrast to the usual case, the Lorentz contraction
of the sphere's volume is taken into account. It is proven that the suggested
EOS obeys the causality in the limit of high densities, i.e., the value of
sound velocity of such a media is subluminar. The pressure obtained for the
high values of chemical potential has an interesting kinetic interpretation.
The suggested EOS shows that for high densities the most probable configuration
corresponds to the smallest value of the relativistic excluded volume. In other
words, for high densities the configurations with the collinear velocities of
the neighboring hard core particles are the most probable ones. This, perhaps,
may shed light on the coalescence process of any relativistic hard core
constituents.


title:
Scaling of Anisotropic Flows in Intermediate Energy and
  Ultra-relativistic Heavy Ion Collisions

abstract:
  Anisotropic flows ($v_2$ and $v_4$) of hadrons and light nuclear clusters are
studied by a partonic transport model and nucleonic transport model,
respectively, in ultra-relativistic and intermediate energy heavy ion
collisions. Both number-of-constituent-quark scaling of hadrons, especially for
$\phi$ meson which is composed of strange quarks, and number-of-nucleon scaling
of light nuclear clusters are discussed and explored for the elliptic flow
($v_2$). The ratios of $v_4/v_2^2$ of hadrons and nuclear clusters are,
respectively, calculated and they show different constant values which are
independent of transverse momentum. The above phenomena can be understood,
respectively, by the coalescence mechanism in quark-level or nucleon-level.


title: High temperature phase of QCD

abstract:
  I give a brief overview of our present understanding of the high temperature
phase of QCD, trying to clarify some of the theoretical issues involved in the
current discussions that emphasize the strongly coupled character of the
quark-gluon plasma produced at RHIC.


title: HBT shape analysis with q-cumulants

abstract:
  Taking up and extending earlier suggestions, we show how two- and
threedimensional shapes of second-order HBT correlations can be described in a
multivariate Edgeworth expansion around gaussian ellipsoids, with expansion
coefficients, identified as the cumulants of pair momentum difference q, acting
as shape parameters. Off-diagonal terms dominate both the character and
magnitude of shapes. Cumulants can be measured directly and so the shape
analysis has no need for fitting.


title:
Theory of the nuclear excitation by electron transition process near the
  K-edge

abstract:
  We propose a model for description of the process of Nuclear Excitation by
Electron Transition (NEET) near the $K$-shell ionization threshold of an atom.
We explain the experimental results for the $^{197}$Au cross section excitation
$\sigma_{N^*}$ obtained by S.Kishimoto et al. Phys. Rev. C {\bf 74}, 031301(R)
(2006) using synchrotron radiation near the Au $K$-edge. We predict the
behavior of $\sigma_{N^*}$ as a function of the incident photon energy for
nuclei $^{193}$Ir and $^{189}$Os. We reveal that the $^{189}$Os excitation
begins when the energy of incident photons is below the $K$-shell ionization
threshold in Os.


title: QMC calculations of symmetric nuclear matter

abstract:
  We present an accurate numerical study of the equation of state of nuclear
matter based on realistic nucleon--nucleon interactions by means of Auxiliary
Field Diffusion Monte Carlo (AFDMC) calculations. The AFDMC method samples the
spin and isospin degrees of freedom allowing for quantum simulations of large
nucleonic systems and represents an important step forward towards a
quantitative understanding of problems in nuclear structure and astrophysics.


title: Long-range chiral dynamics of $\Lambda$-hyperon in nuclear media

abstract:
  We extend a chiral effective field theory approach to the $\Lambda$-nuclei
interaction with the inclusion of the decuplet baryons. More precisely, we
study the contributions due to the long-range two-pion exchange, with $\Sigma$
and $\Sigma^*$ baryons in the internal baryonic lines considering Nh and
$\Delta$h excitations. In particular, central and spin-orbit potentials are
studied. For the former, regularization is needed and physical values of the
cut-off give a large attraction, becoming necessary to include the repulsion of
other terms not considered here. For the latter, in a model-independent
framework, the inclusion of the decuplet supports the natural explanation of
the smallness of the $\Lambda$-nuclear spin-orbit term and shows the importance
of the $\Sigma^*$ and $\Delta$ degrees of freedom for the hyperon-nucleus
interactions.


title: Initial Parton Distribution just after Heavy Ion Collisions

abstract:
  We study the initial distribution of a parton system which is formed just
after relativistic heavy ion collision by the elastic scattering among the
constituent partons in details and analyze the baryon and strangeness contents
of the primary parton system. We present the rapidity and energy distributions
of the system.


title:
Empirical formula for the excitation energies of the first $2^+$ and
  $3^-$ states in even-even nuclei

abstract:
  We report empirical findings that a simple formula in terms of the mass
number $A$, the valence proton number $N_p$, and the valence neutron number
$N_n$ can describe the essential trends of excitation energies $E_x$ of the
first $2^+$ and $3^-$ states in even-even nuclei throughout the periodic table.
The formula reads as $E_x = \alpha A^{-\beta} + \exp (- \lambda N_p) + \exp (-
\lambda N_n)$. The parameter $\beta$ in the first term is determined by the
mass number $A$ dependence of the bottom contour line of the excitation energy
systematics. The other two parameters $\alpha$ and $\lambda$ are fitted by
minimizing the $\chi^2$ value between the measured and calculated excitation
energies. Our results suggest that the single large-$j$ shell simulation can be
applied to the excitation energies of the first $2^+$ and $3^-$ states in
even-even nuclei.


title:
Behaviour of the $\Lambda N$ and $\Lambda NN$ potential strengths in the
  $_\Lambda ^5$He hypernucleus

abstract:
  Variational study of $_\Lambda ^5$He hypernucleus is presented using a
realistic Hamiltonian and a fully correlated wave function including $\Lambda
N$ space-exchange correlation. Behaviour of the $\Lambda$-separation energy
($B_\Lambda$) with two- and three- baryon potential strengths is thoroughly
investigated. Solutions of the potential strengths giving experimental
$B_\Lambda$ are presented.


title:
Behaviour of the potentials due to strangeness degree of freedom in
  $_{\Lambda\Lambda}^6$He hypernucleus

abstract:
  Fully correlated study of $_{\Lambda\Lambda} ^6$He hypernucleus has been
performed with two- and three- baryon potentials. For the S=-2 sector, various
simulations of Nijmegen $\Lambda\Lambda$ potential models have been used. We
investigate the role of every strength of the strange sector potentials on the
energy breakdown and present a crystal clear understanding of their interplay.
Consistency between $_\Lambda ^5$He and $_{\Lambda\Lambda}^6$He depends on the
$\Lambda N$ space-exchange strength only. Investigation limits the strength of
simulated Nijmegen $\Lambda\Lambda$ potential models. The study is a step
forward to determine all the strengths, to reslove A=5 anomaly and to search
for $_{\Lambda\Lambda}^4$H in an authentic way.


title: Shapes and Sizes from Non-Identical-Particle Correlations

abstract:
  I review the prospects for measuring source characteristics from correlations
other than those involving identical pions. Correlations generated from Coulomb
and strong interactions are shown to provide remarkable resolving power for
determining three-dimensional information, in some cases accessing more detail
than can be represented by Gaussian fits.


title: A possible Omega-pi molecular state

abstract:
  The structure of Omega-pi state with isospin I=1 and spin-parity J^p=3/2^-
are dynamically studied in both the chiral SU(3) quark model and the extended
chiral SU(3) quark model by solving a resonating group method (RGM) equation.
The model parameters are taken from our previous work, which gave a
satisfactory description of the energies of the baryon ground states, the
binding energy of the deuteron, the nucleon-nucleon (NN) scattering phase
shifts, and the hyperon-nucleon (YN) cross sections. The calculated results
show that the Omega-pi state has an attractive interaction, and in the extended
chiral SU(3) quark model such an attraction can make for an Omega-pi
quasi-bound state with the binding energy of about several MeV.


title: New Results in the CBF theory for medium-heavy nuclei

abstract:
  Momentum distributions, spectroscopic factors and quasi-hole wave functions
of medium-heavy doubly closed shell nuclei have been calculated in the
framework of the Correlated Basis Function theory, by using the Fermi
hypernetted chain resummation techniques. The calculations have been done by
using microscopic two-body nucleon-nucleon potentials of Argonne type, together
with three-body interactions. Operator dependent correlations, up to the tensor
channels, have been used.


title: Inclusive electron scattering off 4He

abstract:
  Inclusive electron scattering off 4He is calculated exactly with a complete
treatment of the final state interaction within a simple semirealistic
potential model. We discuss results for both the longitudinal and the
transverse response functions, at various momentum transfers. A consistent
meson exchange current is implemented. Good agreement with available
experimental data is found for the longitudinal response function, while some
strength is still missing in the transverse response function.


title: A Co-moving Coordinate System for Relativistic Hydrodynamics

abstract:
  The equations of relativistic hydrodynamics are transformed so that steps
forward in time preserves local simultaneity. In these variables, the
space-time coordinates of neighboring points on the mesh are simultaneous
according to co-moving observers. Aside from the time step varying as a
function of the location on the mesh, the local velocity gradient and the local
density then evolve according to non-relativistic equations of motion. Analytic
solutions are found for two one-dimensional cases with constant speed of sound.
One solution has a Gaussian density profile when mapped into the new
coordinates. That solution is analyzed for the effects of longitudinal
acceleration in relativistic heavy ion collisions at RHIC, especially in
regards to two-particle correlation measurements of the longitudinal size.


title: Wobbling motion in triaxial superdeformed nuclei

abstract:
  We discuss some characteristic features of the wobbling motion excited on the
triaxial superdeformed Lu nucleus. We show how these features are connected to
the moments of inertia microscopically calculated by means of the quasiparticle
RPA in the rotating frame.


title:
Study of the ground-state energy of 40Ca with the CD-Bonn
  nucleon-nucleon potential

abstract:
  We have calculated the ground-state energy of the doubly-magic nucleus 40Ca
within the framework of the Goldstone expansion using the CD-Bonn
nucleon-nucleon potential. The short-range repulsion of this potential has been
renormalized by integrating out its high-momentum components so as to derive a
low-momentum potential V-low-k defined up to a cutoff momentum Lambda. A simple
criterion has been employed to establish a connection between this cutoff
momentum and the size of the two-nucleon model space in the harmonic oscillator
basis. This model-space truncation approach provides a reliable way to
renormalize the free nucleon-nucleon potential preserving its many-body
physics. The role of the 3p-3h and 4p-4h excitations in the description of the
ground state of 40Ca is discussed.


title: Electromagnetic nucleon form factors in instant and point form

abstract:
  We present a study of the electromagnetic structure of the nucleons with
constituent quark models in the framework of relativistic quantum mechanics. In
particular, we address the construction of spectator-model currents in the
instant and point forms. Corresponding results for the elastic nucleon
electromagnetic form factors as well as charge radii and magnetic moments are
presented. We also compare results obtained by different realistic nucleon wave
functions stemming from alternative constituent quark models. Finally, we
discuss the theoretical uncertainties that reside in the construction of
spectator-model transition operators.


title:
Analytical Form of the Deuteron Wave Function Calculated within the
  Dispersion Approach

abstract:
  We present a convenient analytical parametrization of the deuteron wave
function calculated within dispersion approach as a discrete superposition of
Yukawa-type functions, in both configuration and momentum spaces.


title: Critical-Point Structure in Finite Nuclei

abstract:
  Properties of quantum shape-phase transitions in finite nuclei are considered
in the framework of the interacting boson model. Special emphasis is paid to
the dynamics at the critical-point of a general first-order phase transition.


title:
Photodisintegration of light nuclei for testing a correlated realistic
  interaction in the continuum

abstract:
  An exact calculation of the photodisintegration cross section of 3H, 3He and
4He is performed using as interaction the correlated Argonne V18 potential,
constructed within the Unitary Correlation Operator Method (VUCOM).
  Calculations are carried out using the
  Lorentz Integral Transform method in conjunction with an hyperspherical
harmonics basis expansion. A comparison with other realistic potentials and
with available experimental data is discussed. The VUCOM potential leads to a
very similar description of the cross section as the Argonne V18 interaction
with the inclusion of the Urbana IX three-body force for photon energies 45< w
< 120 MeV, while larger differences are found close to threshold.


title: Bimodal fission in the Skyrme-Hartree-Fock approach

abstract:
  Spontaneous-fission properties of 256Fm, 258Fm, and 260Fm isotopes are
studied within the Skyrme-Hartree-Fock+BCS framework. In the particle-hole
channel we take the Skyrme SkM* effective force, while in the particle-particle
channel we employ the seniority pairing interaction. Three static fission paths
for all investigated heavy fermium isotopes are found. The analysis of these
fission modes allows to describe observed asymmetric fission of 256Fm, as well
as bimodal fission of 258Fm and symmetric fission in 260Fm.


title: A new puzzle for random interaction

abstract:
  We continue a series of numerical experiments on many-body systems with
random two-body interactions, by examining correlations in ratios in excitation
energies of yrast $J$ = 0, 2, 4, 6, 8 states. Previous studies, limited only to
$J$ = 0,2,4 states, had shown strong correlations in boson systems but not
fermion systems. By including $J \ge 6$ states and considering different
scatter plots, strong and realistic correlations appear in both boson and
fermion systems. Such correlations are a challenge to explanations of random
interactions.


title: Quantum Phase Transitions in a Finite System

abstract:
  A general procedure for studying finite-N effects in quantum phase
transitions of finite systems is presented and applied to the critical-point
dynamics of nuclei undergoing a shape-phase transition of second-order
(continuous), and of first-order with an arbitrary barrier.


title: Cluster structure of a low-energy resonance in tetraneutron

abstract:
  We theoretically investigate the possibility for a tetraneutron to exist as a
low-energy resonance state. We explore a microscopic model based on the
assumption that the tetraneutron can be treated as a compound system where
$^3$n+n and $^2$n+$^2$n coupled cluster configurations coexist. The influence
of the Pauli principle on the kinetic energy of the relative motion of the
neutron clusters is shown to result in their attraction. The strength of such
attraction is high enough to ensure the existence of a low-energy resonance in
the tetraneutron, provided that the oscillator length is large enough.


title: Neutron stars and quark matter

abstract:
  Recent observations of neutron star masses close to the maximum predicted by
nucleonic equations of state begin to challenge our understanding of dense
matter in neutron stars, and constrain the possible presence of quark matter in
their deep interiors.


title: No-Core shell model for A = 47 and A = 49

abstract:
  We apply an {\it ab-initio} approach to the nuclear structure of odd-mass
nuclei straddling $^{48}Ca$. Starting with the NN interaction, that fits
two-body scattering and bound state data we evaluate the nuclear properties of
$A = 47$ and $A = 49$ nuclei in a no-core approach. Due to model space
limitations and the absence of 3-body interactions, we incorporate
phenomenological terms determined by fits to $A = 48$ nuclei in a previous
effort. Our modified Hamiltonian produces reasonable spectra for these odd mass
nuclei. In addition to the differences in single-particle basis states, the
absence of a single-particle Hamiltonian in our no-core approach obscures
direct comparisons with valence effective NN interactions. Nevertheless, we
compare the fp-shell matrix elements of our initial and modified Hamiltonians
in the harmonic oscillator basis with a recent model fp-shell interaction, the
GXPF1 interaction of Honma, Otsuka, Brown and Mizusaki. Notable differences
emerge from these comparisons. In particular, our diagonal two-body $T = 0$
matrix elements are, on average, about 800-900keV more attractive. Furthermore,
while our initial and modified NN Hamiltonian fp-shell matrix elements are
strongly correlated, there is much less correlation with the GXPF1 matrix
elements.


title: Quantum Shape-Phase Transitions in Finite Nuclei

abstract:
  Quantum shape-phase transitions in finite nuclei are considered in the
framework of the interacting boson model. Critical-point Hamiltonians for
first- and second-order transitions are identified by resolving them into
intrinsic and collective parts. Suitable wave functions and finite-N estimates
for observables at the critical-points are derived.


title: Nucleon Form Factors in Point-Form Spectator-Model Constructions

abstract:
  We discuss electromagnetic currents in the point-form formulation of
relativistic quantum mechanics. The construction is along a spectator model and
implies that only one quark is explicitly coupled to the photon, but
nevertheless many-body contributions are present in the current operator. Such
effects are unavoidable in relativistic constructions and resulting ambiguities
are notably reduced by imposing charge normalization and time-reversal
invariance. The residual theoretical indetermination introduces small but
sizeable changes in the nucleon form-factors, particularly at higher Q-squared
values, with the data generally centered in the middle of the theoretical band.


title:
Helium-cluster decay widths of molecular states in beryllium and carbon
  isotopes

abstract:
  The $\alpha$ particle and $^6$He emissions from possible molecular states in
beryllium and carbon isotopes have been studied using a mean-field-type cluster
potential. Calculations can reproduce well the $\alpha$-decay widths of excited
states in $^{8}$Be, $^{12}$C and $^{20}$Ne. For the nucleus $^{10}$Be, we
discussed the $\alpha$-decay widths with different shapes or decay modes, in
order to understand the very different decay widths of two excited states. The
widths of $^{6}$He decay from $^{12}$Be and $\alpha$ decays from $^{13,14}$C
are predicted, which could be useful for future experiments.


title: Chiral pion-nucleon dynamics in finite nuclei: spin-isospin excitations

abstract:
  The nuclear density functional framework, based on chiral dynamics and the
symmetry breaking pattern of low-energy QCD, is extended to the description of
collective nuclear excitations. Starting from the relativistic point-coupling
Lagrangian previously introduced [Nucl. Phys. A770 (2006) 1], the
proton-neutron (quasiparticle) random phase approximation is formulated and
applied to investigate the role of chiral pion-nucleon dynamics in excitation
modes involving spin and isospin degrees of freedom, e.g. isobaric analog
states and Gamow-Teller resonances.


title: Mind the gap

abstract:
  In this summary of the application of Dyson-Schwinger equations to the theory
and phenomenology of hadrons, some deductions following from a nonperturbative,
symmetry-preserving truncation are highlighted, notable amongst which are
results for pseudoscalar mesons. We also describe inferences from the gap
equation relating to the radius of convergence of a chiral expansion,
applications to heavy-light and heavy-heavy mesons, and quantitative estimates
of the contribution of quark orbital angular momentum in pseudoscalar mesons;
and recapitulate upon studies of nucleon electromagnetic form factors.


title: Decay Properties Of The Dipole Isobaric Analog Resonances

abstract:
  A continuum-RPA-based approach is applied to describe the decay properties of
isolated dipole isobaric analog resonances in nuclei having not-too-large
neutron excess. Calculated for a few resonances in 90Zr the elastic
E1-radiative width and partial proton widths for decay into one-hole states of
89Y are compared with available experimental data.


title: Systematic analysis of reaction cross sections of carbon isotopes

abstract:
  We systematically analyze total reaction cross sections of carbon isotopes
with N=6--16 on a $^{12}$C target for wide range of incident energy. The
intrinsic structure of the carbon isotope is described by a Slater determinant
generated from a phenomenological mean-field potential, which reasonably well
reproduces the ground state properties for most of the even $N$ isotopes. We
need separate studies not only for odd nuclei but also for $^{16}$C and
$^{22}$C. The density of the carbon isotope is constructed by eliminating the
effect of the center of mass motion. For the calculations of the cross
sections, we take two schemes: one is the Glauber approximation, and the other
is the eikonal model using a global optical potential. We find that both of the
schemes successfully reproduce low and high incident energy data on the cross
sections of $^{12}$C, $^{13}$C and $^{16}$C on $^{12}$C. The calculated
reaction cross sections of $^{15}$C are found to be considerably smaller than
the empirical values observed at low energy. We find a consistent
parameterization of the nucleon-nucleon scattering amplitude, differently from
previous ones. Finally, we predict the total reaction cross section of $^{22}$C
on $^{12}$C.


title:
Transport model analysis of the transverse momentum and rapidity
  dependence of pion interferometry at SPS energies

abstract:
  Based on the UrQMD transport model, the transverse momentum and the rapidity
dependence of the Hanbury-Brown-Twiss (HBT) radii $R_L$, $R_O$, $R_S$ as well
as the cross term $R_{OL}$ at SPS energies are investigated and compared with
the experimental NA49 and CERES data. The rapidity dependence of the $R_L$,
$R_O$, $R_S$ is weak while the $R_{OL}$ is significantly increased at large
rapidities and small transverse momenta. The HBT "life-time" issue (the
phenomenon that the calculated $\sqrt{R_O^{2}-R_S^{2}}$ value is larger than
the correspondingly extracted experimental data) is also present at SPS
energies.


title:
Double beta decay to the first $2^+$ state within a boson expansion
  formalism with a projected spherical single particle basis

abstract:
  The Gamow-Teller transition operator is written as a polynomial in the dipole
proton-neutron and quadrupole charge conserving QRPA boson operators, using the
prescription of the boson expansion technique of Belyaev-Zelevinski type. Then,
the $2\nu\beta\beta$ process ending on the first $2^+$ state in the daughter
nucleus is allowed via one, two and three boson states describing the odd-odd
intermediate nucleus. The approach uses a single particle basis which is
obtained by projecting out the good angular momentum from an orthogonal set of
deformed functions. The basis for mother and daughter nuclei have different
deformations. The GT transition amplitude as well as the half lives were
calculated for ten transitions.
  Results are compared with the available data as well as with some predictions
obtained with other methods.


title: Chiral Dynamics from Dyson-Schwinger Equations

abstract:
  A strongly momentum-dependent dressed-quark mass function is basic to QCD. It
is central to the appearance of a constituent-quark mass-scale and an
existential prerequisite for Goldstone modes. Dyson-Schwinger equation (DSE)
studies have long emphasised these facts and are a natural way to exploit them.


title:
The role of local and global strangeness neutrality at the inhomogeneous
  freeze-out in relativistic heavy ion collisions

abstract:
  The decoupling surface in relativistic heavy-ion collisions may not be
homogeneous. Rather, inhomogeneities should form when a rapid transition from
high to low entropy density occurs. We analyze the hadron "chemistry" from
high-energy heavy-ion reactions for the presence of such density
inhomogeneities. We show that due to the non-linear dependence of the particle
densities on the temperature and baryon-chemical potential such inhomogeneities
should be visible even in the integrated, inclusive abundances. We analyze
experimental data from Pb+Pb collisions at CERN-SPS and Au+Au collisions at
BNL-RHIC to determine the amplitude of inhomogeneities and the role of local
and global strangeness neutrality.


title: Electromagnetic Dissociation and Space Radiation

abstract:
  Relativistic nucleus-nucleus reactions occur mainly through the Strong or
Electromagnetic (EM) interactions. Transport codes often neglect the latter.
This work shows the importance of including EM interactions for space radiation
applications.


title: Quantum Monte Carlo calculations of neutron-alpha scattering

abstract:
  We describe a new method to treat low-energy scattering problems in
few-nucleon systems, and we apply it to the five-body case of neutron-alpha
scattering. The method allows precise calculations of low-lying resonances and
their widths. We find that a good three-nucleon interaction is crucial to
obtain an accurate description of neutron-alpha scattering.


title: Kaon Absorption from Kaonic Atoms and Formation Spectra of Kaonic Nuclei

abstract:
  We considered the kaon absorption from atomic states into nucleus. We found
that the nuclear density probed by the atomic kaon significantly depends on the
kaon orbit. Then, we reexamined the meanings of the observed strengths of
one-body and two-body kaon absorption, and investigated the effects to the
formation spectra of kaon bound states by in-flight ($K^-,p$) reactions. As a
natural consequence, if the atomic kaon probes the smaller nuclear density, the
ratio of the two-body absorption at nuclear center is larger than the observed
value, and the depth of the imaginary potential is deeper even at smaller kaon
energies as in kaonic nuclear states because of the large phase space for the
two-body processes.


title:
Properties of the largest fragment in multifragmentation: a canonical
  thermodynamic calculation

abstract:
  Many calculations for the production of light and intermediate particles
resulting from heavy ion collisions at intermediate energies exist.
Calculations of properties of the largest fragment resulting from
multifragmentation are rare. In this paper we compute these properties and
compare them with the data for the case of gold on carbon. We use the canonical
thermodynamic model. The model also gives a bimodal distribution for the
largest fragment in a narrow energy range.


title:
Chiral phase transition and color superconductivity in an extended NJL
  model with higher-order multi-quark interactions

abstract:
  The chiral phase transition and color superconductivity in an extended NJL
model with eight-quark interactions are studied. The scalar-type nonlinear term
hastens the chiral phase transition,the scalar-vector mixing term suppresses
effects of the vector-type linear term and the scalar-diquark mixing term makes
the coexisting phase wider.


title: Correlations in self-bound systems of identical fermions

abstract:
  A method for the calculation of translationally invariant wave functions for
systems of identical fermions with arbitrary potential of pair interaction is
developed. It is based on the well-known result that the essential dynamic part
of the Hamiltonian for the system of identical particles is the Reduced
Hamiltonian operator describing relative movement of two particles inside the
system. The eigenfunctions of this operator take into account all correlations
caused by interaction. These eigenfunctions are basic for the construction of
the components (i.e. the functions with a lower degree of antisymmetry) of the
system wave functions. The main problem of this approach appears to be
antisymmetrization of the components. The developed universal algorithm for
antisymmetrization gives a possibility to perform this operation in a simple
way and keep numerical approximations under control.


title: Three-body model calculations for 16C nucleus

abstract:
  We apply a three-body model consisting of two valence neutrons and the core
nucleus $^{14}$C in order to investigate the ground state properties and the
electronic quadrupole transition of the $^{16}$C nucleus. The discretized
continuum spectrum within a large box is taken into account by using a
single-particle basis obtained from a Woods-Saxon potential. The calculated
B(E2) value from the first 2$^+$ state to the ground state shows good agreement
with the observed data with the core polarization charge which reproduces the
experimental B(E2) value for $^{15}$C. We also show that the present
calculation well accounts for the longitudinal momentum distribution of
$^{15}$C fragment from the breakup of $^{16}$C nucleus. We point out that the
dominant ($d_{5/2})^2$ configuration in the ground state of $^{16}$C plays a
crucial role for these agreement.


title:
Shell-model study of spectroscopies and isospin structures in odd-odd
  $N=Z$ nuclei employing realistic \emph{NN} potentials

abstract:
  The structures of odd-odd $N=Z$ nuclei in the lower \emph{fp} shell have been
investigated with a new isospin-nonconserving microscopical interaction. The
interaction is derived from a high-precision charge-dependent Bonn
nucleon-nucleon potential using the folded-diagram renormalization method.
Excellent agreements with experimental data have been obtained up to band
terminations. Particularly, the relative positions of T=0 and T=1 bands were
well reproduced. Calculations with another interaction obtained from the
Idaho-A chiral potential showed similar results. Our calculations also give a
good description of the existence of high-spin isomeric states in the
$0f_{7/2}$ sub-shell. As examples, the spectroscopies and isospin structures of
$^{46}$V and $^{50}$Mn have been discussed in detail, with the useful
predictions of level structures including electromagnetic properties. Results
for $^{50}$Mn were analyzed where experimental observations are still
insufficient.


title: Hyperon-nucleon interactions in effective field theory

abstract:
  We have constructed the leading order hyperon-nucleon potential in a chiral
Effective Field Theory approach. The chiral potential consists of
one-pseudoscalar-meson exchanges and non-derivative four-baryon contact terms.
The hyperon-nucleon interactions are derived using SU(3) symmetry, the
nucleon-nucleon interaction is not considered explicitly since it can not be
described well with a leading order chiral Effective Field Theory. We solve a
regularized Lippmann-Schwinger equation and show that a good description of the
available hyperon-nucleon scattering data is possible with five free
parameters. The chiral potential can be used as further input for hypernucleus
and hypernuclear matter calculations. Preliminary hypertriton calculations
yielded the correct hypertriton binding energy.


title:
Phenomenological model of the Kaonic Nuclear Cluster K^-pnn in the
  ground state

abstract:
  A phenomenological model, proposed for the Kaonic Nuclear Cluster
  (KNC) K^-pp, is applied to the theoretical analysis of the KNC K^-pnn (or
S^0). The theoretical values of the binding energy and the width are equal to
epsilon_(S^0) = - 197 MeV and Gamma_(S^0) = 16 MeV. They agree well with the
experimental data epsilon^(exp)_(S^0) = - 194.0(+ 1.5/- 4.4) MeV and
Gamma^(exp)_(S^0) < 21 MeV} (PLB 597, 263 (2004)) and the theoretical values
epsilon_(S^0) = - 191 MeV and Gamma_(S^0) = 13 MeV, obtained by Akaishi and
Yamazaki within the potential model approach.


title: Isospin-dependent clusterization of Neutron-Star Matter

abstract:
  Because of the presence of a liquid-gas phase transition in nuclear matter,
compact-star matter can present a region of instability against the formation
of clusters. We investigate this phase separation in a matter composed of
neutrons, protons and electrons, within a Skyrme-Lyon mean-field approach.
Matter instability and phase properties are characterized through the study of
the free-energy curvature. The effect of beta-equilibrium is also analyzed in
detail, and we show that the opacity to neutrinos has an influence on the
presence of clusterized matter in finite-temperature proto-neutron stars.


title: Nucleon sum rules in symmetric and asymmetric nuclear matter

abstract:
  We calculate the nucleon parameters in isospin symmetric and asymmetric
nuclear matter using the QCD sum rules. The higher moments of the nucleon
structure functions are included. The complete set of the nucleon expectation
values of the four-quark operators is employed. We analyze the role of the
lowest order radiative corrections beyond the logarithmic approximation.


title: Quasielastic Charged Current Neutrino-nucleus Scattering

abstract:
  We provide integrated cross sections for quasielastic charged-current
neutrino-nucleus scattering. Results evaluated using the phenomenological
scaling function extracted from the analysis of experimental $(e,e')$ data are
compared with those obtained within the framework of the relativistic impulse
approximation. We show that very reasonable agreement is reached when a
description of final-state interactions based on the relativistic mean field is
included. This is consistent with previous studies of differential cross
sections which are in accord with the universality property of the superscaling
function.


title: Nuclear Superfluidity in Exotic Nuclei and Neutron Stars

abstract:
  Nuclear superfludity in exotic nuclei close to the drip lines and in the
inner crust matter of neutron stars have common features which can be treated
with the same theoretical tools. In the first part of my lecture I discuss how
two such tools, namely the HFB approach and the linear response theory can be
used to describe the pairing correlations in weakly bound nuclei, in which the
unbound part of the energy spectrum becomes important. Then, using the same
models, I shall discuss how the nuclear superfluidity can affect the thermal
properties of the inner crust of neutron stars.


title: Threshold meson production and cosmic ray transport

abstract:
  An interesting accident of nature is that the peak of the cosmic ray
spectrum, for both protons and heavier nuclei, occurs near the pion production
threshold. The Boltzmann transport equation contains a term which is the cosmic
ray flux multiplied by the cross section. Therefore when considering pion and
kaon production from proton-proton reactions, small cross sections at low
energy can be as important as larger cross sections at higher energy. This is
also true for subthreshold kaon production in nuclear collisions, but not for
subthreshold pion production.


title:
Charmonium dynamics in nucleus-nucleus collisions at SPS and FAIR
  energies

abstract:
  Charmonium production and suppression in In+In and Pb+Pb reactions at SPS
energies is investigated with the HSD transport approach within the 'hadronic
comover model' as well as the 'QGP threshold scenario'. The results of the
transport calculations for J/Psi suppression and the Psi prime to J/Psi ratio
are compared with the recent data of the NA50 and NA60 Collaborations. We find
that the comover absorption model - with a single parameter |M_0|^2 for the
matrix element squared for charmonium-meson dissociation - performs best with
respect to all data sets. The 'threshold scenario' - within different
assumptions for the melting energy densities - yields a reasonable suppression
for J/Psi but fails in reproducing the Psi prime to J/Psi ratio for Pb+Pb at
158 A GeV. Predictions for Au+Au reactions are presented for a bombarding
energy of 25 A GeV in the different scenarios which will allow for a clear
distinction between the models from the experimental side at the future FAIR
facility.


title:
Baryonic Effect on chi_cJ Suppression in Au+Au Collisions at RHIC
  Energies

abstract:
  We predict that initially produced chi_cJ mesons at low transverse momentum
in the central rapidity region are almost dissociated by nucleons and
antinucleons in hadronic matter produced in central Au+Au collisions at RHIC
energies sqrt {s_{NN}}= 130 and 200 GeV. In calculations the nucleon and
antinucleon distributions in hadronic matter are results of evolution from
their freeze-out distributions which well fit the experimental p_T spectra of
proton and antiproton. Any measured chi_cJ mesons at low p_T are generated from
deconfined matter and give an explicit proof of regeneration mechanism
(recombination mechanism).


title: The nucleon-nucleon potential beyond the static approximation

abstract:
  We point out that, due to the use of static nucleon propagators in Heavy
Baryon Chiral Perturbation Theory, the current calculations of the
nucleon-nucleon potential miss certain contributions starting at two loops.
These contributions give rise to contact interactions, which are both
parametrically and numerically more important than the so called NNLO
potentials. They show a peculiar dependence on the light quark masses, which
should be taken into account when performing chiral extrapolations of lattice
data. However, they do not appear to have an impact on phenomenology since they
can be absorbed into redefinitions of unknown parameters which are usually
fitted to data.


title: Non-identical particle femtoscopy in models with single freeze-out

abstract:
  We present femtoscopic results from hydrodynamics-inspired thermal models
with single freeze-out. Non-identical particle femtoscopy is studied and
compared to results of identical particle correlations. Special emphasis is put
on shifts between average space-time emission points of non-identical particles
of different masses. They are found to be sensitive to both the spatial shift
coming from radial flow, as well as average emission time difference coming
from the resonance decays. The Therminator Monte-Carlo program was chosen for
this study because it realistically models both of these effects. In order to
analyze the results we present and test the methodology of non-identical
particle correlations.


title: Covariant calculation of nonstrange decays of strange baryon resonances

abstract:
  We report on a study of pi and eta decays of strange baryon resonances within
relativistic constituent-quark models based on one-gluon-exchange and
Goldstone-boson-exchange dynamics. The investigations are performed in the
point form of Poincare-invariant relativistic quantum mechanics with a
spectator-model decay operator. The covariant predictions of the
constituent-quark models underestimate the experimental data in most cases.
These findings are congruent with an earlier study of nonstrange baryon decays
in the light-flavor sector. We also consider a nonrelativistic reduction of the
point-form spectator model, which leads to the decay operator of the elementary
emission model. For some decays the nonrelativistic results differ
substantially from the relativistic ones and they exhibit no uniform behavior
as they scatter above and below the experimental decay widths.


title: Pair production from nuclear collisions and cosmic ray transport

abstract:
  Modern cosmic ray transport codes, that are capable of use for a variety of
applications, need to include all significant atomic, nuclear and particle
reactions at a variety of energies. Lepton pair production from nucleus-nucleus
collisions has not been included in transport codes to date. Using the methods
of Baur, Bertulani and Baron, the present paper provides estimates of
electron-positron pair production cross sections for nuclei and energies
relevant to cosmic ray transport. It is shown that the cross sections are large
compared to other typical processes such as single neutron removal due to
strong or electromagnetic interactions. Therefore lepton pair production may
need to be included in some transport code applications involving MeV
electrons.


title:
Properties of stellar matter in supernova explosions and nuclear
  multifragmentation

abstract:
  During the collapse of massive stars, and the supernova type-II explosions,
stellar matter reaches densities and temperatures which are similar to the ones
obtained in intermediate-energy nucleus-nucleus collisions. The nuclear
multifragmentation reactions can be used for determination of properties of
nuclear matter at subnuclear densities, in the region of the nuclear liquid-gas
phase transition. It is demonstrated that the modified properties of hot nuclei
(in particular, their symmetry energy) extracted from the multifragmentation
data can essentially influence nuclear composition of stellar matter. The
effects on weak processes, and on the nucleosynthesis are also discussed.


title:
Final-state interactions and superscaling in the semi-relativistic
  approach to quasielastic electron and neutrino scattering

abstract:
  The semi-relativistic approach to electron and neutrino quasielastic
scattering from nuclei is extended to include final-state interactions.
Starting with the usual non-relativistic continuum shell model, the problem is
relativized by using the semi-relativistic expansion of the current in powers
of the initial nucleon momentum and relativistic kinematics. Two different
approaches are considered for the final-state interactions: the Smith-Wambach
2p-2h damping model and the Dirac-equation-based potential extracted from a
relativistic mean-field plus the Darwin factor. Using the latter the scaling
properties of $(e,e')$ and $(\nu_\mu,\mu^-)$ cross sections for intermediate
momentum transfers are investigated.


title:
Extended Optical Model Analyses of Elastic Scattering and Fusion Cross
  Sections for 6Li + 208Pb System at Near-Coulomb-Barrier Energies by using
  Folding Potential

abstract:
  Based on the extended optical model approach in which the polarization
potential is decomposed into direct reaction (DR) and fusion parts,
simultaneous $\chi^{2}$ analyses are performed for elastic scattering and
fusion cross section data for the $^{6}$Li+$^{208}$Pb system at
near-Coulomb-barrier energies. A folding potential is used as the bare
potential. It is found that the real part of the resultant DR part of the
polarization potential is repulsive, which is consistent with the results from
the Continuum Discretized Coupled Channel (CDCC) calculations and the
normalization factors needed for the folding potentials. Further, it is found
that both DR and fusion parts of the polarization potential satisfy separately
the dispersion relation.


title:
Equation of State for Hot and Dense Matter: $\sigma$-$\omega$-$\rho $
  Model with Scaled Hadron Masses and Couplings

abstract:
  The proposed earlier relativistic mean-field model with hadron masses and
coupling constants depending on the $\sigma$-meson field is generalized to
finite temperatures. Within this approach we simulate the in-medium behavior of
the hadron masses motivated by the Brown-Rho scaling. The high-lying baryon
resonances and boson excitations as well as excitations of the $\sigma$,
$\omega$ and $\rho$ fields interacting via mean fields are incorporated into
this scheme. Thermodynamic properties of hot and dense hadronic matter are
elaborated with the constructed equation of state. Even at zero baryon density,
effective masses of $\sigma$-$\omega$-$\rho$-$N$ excitations abruptly drop down
for $T\gsim 170$ MeV and reach zero at a critical temperature
$T=T_{c\sigma}\sim 210$ MeV. Below $T_{c\sigma}$ (at $T\sim 190$ MeV) the
specific heat gets a peak like at crossover. We demonstrate that our EoS can be
matched with that computed on the lattice for high temperatures provided the
baryon resonance couplings with nucleon are partially suppressed. In this case
the quark liquid would masquerade as the hadron one. The model is applied to
description of heavy ion collisions in a broad collision energy range. It might
be especially helpful for studying phase diagram in the region near possible
phase transitions.


title: Mass and width of strange baryon resonances in QCD sum rules

abstract:
  The mass spectra of strange baryons in the octet family are investigated in a
finite-energy QCD sum rule approach based on the Gauss-Weierstrass transform.
The phenomenological form of the spectral function is saturated by the ground
state and two of the lowest excited states, considered as having opposite
parities. Treating the ground state parameters as known, the masses, widths and
couplings to the interpolating fields are determined and compared to
experiment.


title: Quantised orbital alignment and Identical High-K Bands in A=180 region

abstract:
  The origin of the identical gamma-ray energies (IB) observed in the
K=33/2$^+$ and K=16$^+$ bands in $^{177}$Lu and $^{178}$Hf respectively is
investigated using deformed Hartree-Fock and Angular Momentum Projection
technique. We find that quantised orbital (rather than spin) alignment of
protons in the m=1/2$^+$ inert orbit leads to identical energy spectra. A
K=16$^+$ band with identical spectrum is predicted in $^{176}$Yb at 4.48 Mev of
excitation.


title:
pT distribution of hyperons in 200A GeV Au-Au by smoothed particle
  hydrodynamics

abstract:
  The transverse momentum distributions for hadrons in 200GeV Au-Au collision
at RHIC is calculated using a smoothed particle hydrodynamics code SPheRIO, and
are compared with the data from STAR and PHOBOS Collaborations. By employing
the equation of state which explicitly incorporate the strangeness conservation
and introducing strangeness chemical potential into the code, the transverse
spectrums give a reasonable description for the experimental data.


title:
On the resonance spectra of particle-unstable light nuclei with a
  Sturmian approach that preserves the Pauli principle

abstract:
  The fundamental ingredients of the MCAS (multi-channel algebraic scattering)
method are discussed. The main feature, namely the application of the sturmian
theory for nucleon-nucleus scattering, allows solution of the scattering
problem given the phenomenological ingredients necessary for the description of
weakly-bound (or particle-unstable) light nuclear systems. Currently, to
describe these systems, we use a macroscopic, collective model. Analyses show
that the couplings to low-energy collective-core excitations are fundamental
but they are physically meaningful only if the constraints introduced by the
Pauli principle are taken into account. For this we introduce in the
nucleon-nucleus system the Orthogonalizing Pseudo-Potential formalism, extended
to collective excitations of the core. The formalism leads one to discuss a new
concept, Pauli hindrance, which appears to be important especially to
understand the structure of weakly-bound and unbound systems.


title: Baryon-Baryon Interactions from the Lattice

abstract:
  I discuss the latest progress in calculating baryon-baryon interactions with
lattice QCD. The latest results from the NPLQCD collaboration for
nucleon-nucleon scattering along with preliminary calculations of
hyperon-nucleon scattering are presented.


title:
Extended Theory of Finite Fermi Systems: Application to the collective
  and non-collective E1 strength in $^{208}$Pb

abstract:
  The Extended Theory of Finite Fermi Systems is based on the conventional
Landau-Migdal theory and includes the coupling to the low-lying phonons in a
consistent way. The phonons give rise to a fragmentation of the single-particle
strength and to a compression of the single-particle spectrum. Both effects are
crucial for a quantitative understanding of nuclear structure properties. We
demonstrate the effects on the electric dipole states in $^{208}$Pb (which
possesses 50% more neutrons then protons) where we calculated the low-lying
non-collective spectrum as well as the high-lying collective resonances. Below
8 MeV, where one expects the so called isovector pygmy resonances, we also find
a strong admixture of isoscalar strength that comes from the coupling to the
high-lying isoscalar electric dipole resonance, which we obtain at about 22
MeV. The transition density of this resonance is very similar to the breathing
mode, which we also calculated. We shall show that the extended theory is the
correct approach for self-consistent calculations, where one starts with
effective Lagrangians and effective Hamiltonians, respectively, if one wishes
to describe simultaneously collective and non-collective properties of the
nuclear spectrum. In all cases for which experimental data exist the agreement
with the present theory results is good.


title: Nuclear polarizability of helium isotopes in atomic transitions

abstract:
  We estimate the nuclear polarizability correction to atomic transition
frequencies in various helium isotopes. This effect is non-negligible for high
precision tests of quantum electrodynamics or accurate determination of the
nuclear charge radius from spectroscopic measurements in helium atoms and ions.
In particular, it amounts to $28(3)$ kHz for 1S-2S transition in 4He+.


title:
Dirac-Brueckner-Hartree-Fock calculations for isospin asymmetric nuclear
  matter based on improved approximation schemes

abstract:
  We present Dirac-Brueckner-Hartree-Fock calculations for isospin asymmetric
nuclear matter which are based on improved approximations schemes. The
potential matrix elements have been adapted for isospin asymmetric nuclear
matter in order to account for the proton-neutron mass splitting in a more
consistent way. The proton properties are particularly sensitive to this
adaption and its consequences, whereas the neutron properties remains almost
unaffected in neutron rich matter. Although at present full Brueckner
calculations are still too complex to apply to finite nuclei, these
relativistic Brueckner results can be used as a guidance to construct a density
dependent relativistic mean field theory, which can be applied to finite
nuclei. It is found that an accurate reproduction of the
Dirac-Brueckner-Hartree-Fock equation of state requires a renormalization of
these coupling functions.


title:
Annihilation Mechanisms of Lepton Pair Production in Relativistic
  Nuclear Collisions

abstract:
  The pion and quark annihilation mechanisms of dilepton production during
relativistic nuclear collisions are studied. We focus on the modifications
caused by the specific features of in-medium pion and quark states rather than
by medium modification of the $\rho $-meson spectral density. The main
ingredient emerging in our approach is a form-factor of the multi-pion
(multi-quark) system. Replacing the usual delta-function the form-factor plays
the role of distribution which, in some sense, "connects" the total 4-momenta
of the annihilating and outgoing particles. The difference between the c.m.s.
velocities attributed to annihilating and outgoing particles is a particular
consequence of this replacement and results in the appearance of a new factor
in the formula for the lepton pair production rate. We obtained that the
form-factor of the multi-pion (multi-quark) system causes broadening of the
rate which is most pronounced for small invariant masses, in particular, we
obtain a growth of the rate for the invariant masses below two masses of the
annihilating particles.


title:
How does transverse (hydrodynamic) flow affect jet-broadening and
  jet-quenching ?

abstract:
  We give the modification of formulas for $p_{\perp}$-broadening and energy
loss which are necessary to calculate parton interactions in a medium with
flow. Arguments are presented leading to the conclusion that for large
$p_{\perp}$-spectra observed in heavy ion collisions at RHIC, the influence of
transverse flow on the determination of the "quenching power" of the produced
medium is small. This leaves open the question of the interpretation of data in
a consistent perturbative framework.


title: Vector meson form factors and their quark-mass dependence

abstract:
  The electromagnetic form factors of vector mesons are calculated in an
explicitly Poincar\'e covariant formulation, based on the Dyson--Schwinger
equations of QCD, that respects electromagnetic current conservation, and
unambiguously incorporates effects from vector meson poles in the quark-photon
vertex. This method incorporates a 2-parameter effective interaction, where the
parameters are constrained by the experimental values of chiral condensate and
$f_{\pi}$. This approach has successfully described a large amount of
light-quark meson experimental data, e.g. ground state pseudoscalar masses and
their electromagnetic form factors; ground state vector meson masses and strong
and electroweak decays. Here we apply it to predict the electromagnetic
properties of vector mesons. The results for the static properties of the
$\rho$-meson are: charge radius $<r_\rho^2 > = 0.54 {\rm fm}^2$, magnetic
moment $\mu = 2.01$, and quadrupole moment ${\cal Q} = -0.41$. We investigate
the quark mass dependence of these static properties and find that our results
at the charm quark mass are in agreement with recent lattice simulations. The
charge radius decreases with increasing quark mass, but the magnetic moment is
almost independent of the quark mass.


title:
Microscopic Restoration of Proton-Neutron Mixed Symmetry in Weakly
  Collective Nuclei

abstract:
  Starting from the microscopic low-momentum nucleon-nucleon interaction V{low
k}, we present the first systematic shell model study of magnetic moments and
magnetic dipole transition strengths of the basic low-energy one-quadrupole
phonon excitations in nearly-spherical nuclei. Studying in particular the
even-even N=52 isotones from 92Zr to 100Cd, we find the predicted evolution of
the predominantly proton-neutron non-symmetric state reveals a restoration of
collective proton-neutron mixed-symmetry structure near mid-shell. This
provides the first explanation for the existence of pronounced collective
mixed-symmetry structures in weakly-collective nuclei.


title:
The relativistic impulse approximation for the exclusive
  electrodisintegration of the deuteron

abstract:
  The electrodisintegration of the deuteron in the frame of the Bethe-Salpeter
approach with a separable kernel of the nucleon-nucleon interaction is
considered. This conception keeps the covariance of a description of the
process. A comparison of relativistic and nonrelativistic calculations is
presented. The factorization of the cross section of the reaction in the
impulse approximation is obtained by analytical calculations. It is shown that
the photon-neutron interaction plays an important role.


title: Testing superscaling predictions in electroweak excitations of nuclei

abstract:
  Superscaling analysis of electroweak nuclear response functions is done for
momentum transfer values from 300 to 700 MeV/c. Some effects, absent in the
Relativistic Fermi Gas model, where the superscaling holds by construction, are
considered. From the responses calculated for the 12C, 16O and 40Ca nuclei, we
have extracted a theoretical universal superscaling function similar to that
obtained from the experimental responses. Theoretical and empirical universal
scaling functions have been used to calculate electron and neutrino cross
sections. These cross sections have been compared with those obtained with a
complete calculation and, for the electron scattering case, with the
experimental data.


title: Microscopic Cluster Model for Exotic Nuclei

abstract:
  For a better understanding of the dynamics of exotic nuclei it is of crucial
importance to develop a practical microscopic theory easy to be applied to a
wide range of masses. Theoretically the basic task consists in formulating an
easy solvable theory able to reproduce structures and transitions of known
nuclei which should be then used to calculate the sparely known properties of
proton- or neutron-rich nuclei. In this paper we start by calculating energies
and distributions of A\leq4 nuclei withing a unitary correlation model
restricted to include only two-body correlations. The structure of complex
nuclei is then calculated extending the model to include correlation effects of
higher order.


title:
Pairing interactions and the vanishing pairing correlations in hot
  nuclei

abstract:
  Finite temperature Hartree-Fock-Bogoliubov calculations are performed in Sn
isotopes using Skyrme and zero-range, density-dependent pairing interactions.
For both stable and very neutron-rich nuclei the critical temperature at which
pairing correlations vanish is independent of the volume/surface nature of the
pairing interaction. The value of the critical temperature follows
approximatively the empirical rule T$_c$ $\simeq$ 0.5 $\Delta_{T=0}$ for all
the calculated isotopes, showing that the critical temperature could be deduced
from the pairing gap at zero temperature. On the other hand, the pairing gap at
temperatures just below T$_c$ is strongly sensitive to the volume/surface
nature of the pairing interaction.


title: 11Li beta decay into 9Li and deuteron within a three-body model

abstract:
  The beta decay process of the 11Li halo nucleus into 9Li and d is studied in
a three-body model. The 11Li nucleus is described as a 9Li+n+n system in
hyperspherical coordinates on a Lagrange mesh. Various 9Li+d potentials are
compared involving a forbidden state, a physical bound state, and a resonance
near 0.25 MeV in the s-wave. With an added surface absorption, they are
compatible with elastic scattering data. The transition probability per time
unit is quite sensitive to the location of the resonance. For a fixed resonance
location, it does not depend much on the potential choice at variance with the
6He delayed deuteron decay. The calculated transition probability per time unit
is larger than the experimental value but the difference can be explained by a
slightly higher resonance location and/or by absorption from the 9Li+d final
channel.


title:
Analyzing Correlation Functions with Tesseral and Cartesian Spherical
  Harmonics

abstract:
  The dependence of inter-particle correlations on the orientation of particle
relative-momentum can yield unique information on the space-time features of
emission in reactions with multiparticle final states. In the present paper,
the benefits of a representation and analysis of the three-dimensional
correlation information in terms of surface spherical harmonics is presented.
The harmonics include the standard complex tesseral harmonics and the real
cartesian harmonics. Mathematical properties of the lesser-known cartesian
harmonics are illuminated. The physical content of different angular harmonic
components in a correlation is described. The resolving power of different
final-state effects with regarding to determining angular features of emission
regions is investigated. The considered final-state effects include identity
interference and strong and Coulomb interactions. The correlation analysis in
terms of spherical harmonics is illustrated with the cases of gaussian and
blast-wave sources for proton-charged meson and baryon-baryon pairs.


title: In-medium properties of D-mesons at FAIR

abstract:
  We obtain the D-meson spectral density at finite temperature for the
conditions of density and temperature expected at FAIR. We perform a
self-consistent coupled-channel calculation taking, as a bare interaction, a
separable potential model. The $\Lambda_c$ (2593) resonance is generated
dynamically. We observe that the D-meson spectral density develops a sizeable
width while the quasiparticle peak stays close to the free position. The
consequences for the D-meson production at FAIR are discussed.


title: Correlations in hypernuclear matter

abstract:
  We investigate short range correlations in nuclear and hypernuclear matter.
Self-energies due to short range correlations and their influence on the
nucleon and $\Lambda$-hyperon spectral functions are described in an approach
accounting for a realistic treatment of mean-field dynamics and a
self-consistently derived quasi-particle interaction. Landau-Migdal theory is
used to derived the short range interaction from a phenomenological Skyrme
energy density functional, subtracting the long range pionic contributions to
the nucleonic spectral functions. We discuss our results for different
hyperon-baryon ratios to show the influence of strangeness on the correlations
in hypernuclear matter.


title:
Precise determination of low-Q nucleon electromagnetic form factors and
  their impact on parity-violating e-p elastic scattering

abstract:
  The extraction of the strangeness form factors from parity violating elastic
electron-proton scattering is sensitive to the electromagnetic form factors at
low Q^2. We provide parameterizations for the form factors and uncertainties,
including the effects of two-photon exchange corrections to the extracted EM
form factors. We study effect of the correlations between different form
factors, in particular as they impact the parity violating asymmetry and the
extraction of the strangeness form factors. We provide a prescription to
extract the strangeness form factors from the asymmetry that provides an
excellent approximation of the full two-photon correction. The corrected form
factors are also appropriate as input for other low-Q analyses, although the
effects of correlations and two-photon exchange corrections may be different.


title: Global Conservation Laws and Femtoscopy of Small Systems

abstract:
  It is increasingly important to understand, in detail, two-pion correlations
measured in p+p and d+A collisions. In particular, one wishes to understand the
femtoscopic correlations, in order to compare to similar measurements in heavy
ion collisions. However, in the low-multiplicity final states of these systems,
global conservation laws generate significant N-body correlations which project
onto the two-pion space in non-trivial ways and complicate the femtoscopic
analysis. We discuss a model-independent formalism to calculate and account for
these correlations in measurements.


title:
Parameterized total cross sections for pion production in nuclear
  collisions

abstract:
  Total inclusive cross sections for neutral and charged pion production in
proton-nucleus and nucleus-nucleus reactions have been calculated and compared
to experiment. Nucleon-nucleon theoretical cross sections have been scaled up
to nuclear collisions using a scaling factor similar to $(A_PA_T)^{2/3}$, where
$A_P$ and $A_T$ are the nucleon numbers of the projectile and target nuclei.
Variations in the power of this scaling factor have been studied and a good fit
to experiment is obtained with a small modification of the power. Theoretical
cross sections are written in a form that is very suitable for immediate input
into transport codes.


title: Differential Cross Sections for Electromagnetic Dissociation

abstract:
  Differential cross sections for electromagnetic dissociation in
nucleus-nucleus collisions are calculated. The kinetic energy distribution is
parameterized with a Boltzmann distribution and the angular distribution is
assumed isotropic in the projectile frame. In order to be useful for
three-dimensional transport codes, these cross sections are available in both
the projectile and lab frames. Comparison between theory and experiment is
good. The formalism applies to single and multiple nucleon removal, alpha
particle removal, and fission in electromagnetic reactions of nuclei.


title: Isovector deformation and its link to the neutron shell closure

abstract:
  DWBA analysis of the inelastic $^{30-40}$S$(p,p')$ and $^{18-22}$O$(p,p')$
scattering data measured in the inverse kinematics has been performed to
determine the isoscalar ($\delta_0$) and isovector ($\delta_1$) deformation
lengths of the 2$^+_1$ excitations in the Sulfur and Oxygen isotopes using a
compact folding approach. A systematic $N$-dependence of $\delta_0$ and
$\delta_1$ has been established which shows a link between $\delta_1$ and the
neutron-shell closure. Strong isovector deformations were found in several
cases, e.g., the 2$^+_1$ state in $^{20}$O where $\delta_1$ is nearly three
times larger than $\delta_0$. These results confirm the relation
$\delta_1>\delta_0$ anticipated from the core polarization by the valence
neutrons in the open-shell (neutron rich) nuclei. The effect of neutron shell
closure at N=14 or 16 has been discussed based on the folding model analysis of
the inelastic $^{22}$O+$p$ scattering data at 46.6 MeV/u measured recently at
GANIL.


title: Correlated EoM and Distributions for A=6 Nuclei

abstract:
  Energy spectra and electromagnetic transitions of nuclei are strongly
depending from the correlations of the bound nucleons. Two particle
correlations are responsible for the scattering of model particles either to
low momentum- or to high momentum-states. The low momentum states form the
model space while the high momentum states are used to calculate the G-matrix.
The three and higher order particle correlations do not play a role in the
latter calculation especially if the correlations induced by the scattering
operator are of sufficient short range. They modify however, via the long tail
of the nuclear potential, the Slater determinant of the A particles by
generating excited Slater's determinants. In this work the influence of the
correlations on the level structure and ground state distributions of even open
shell nuclei is analyzed via the boson dynamic correlation model BDCM. The
model is based on the unitary operator $e^S$ ({\it S} is the correlation
operator) formalism which in this paper is presented within a non perturbative
approximation. The low lying spectrum calculated for $^6$Li reproduce very well
the experimental spectrum while for $^6$He a charge radius slightly larger than
that obtained within the isotopic-shift (IS) theory has been calculated. Good
agreement between theoretical and experimental results has been obtained
without the introduction of a genuine three body force.
