Dynamical cluster-decay model for hot and rotating light-mass nuclear
  systems, applied to low-energy $^{32}$S + $^{24}$Mg $\to ^{56}$Ni reaction

abstract:
  The dynamical cluster-decay model (DCM) is developed further for the decay of
hot and rotating compound nuclei (CN) formed in light heavy-ion reactions. The
model is worked out in terms of only one parameter, namely the neck-length
parameter, which is related to the total kinetic energy TKE(T) or effective
Q-value $Q_{eff}(T)$ at temperature T of the hot CN, defined in terms of the
both the light-particles (LP), with $A \leq$ 4, Z $\leq$ 2, as well as the
complex intermediate mass fragments (IMF), with $4 < A < 20, Z > 2$, is
considered as the dynamical collective mass motion of preformed clusters
through the barrier. Within the same dynamical model treatment, the LPs are
shown to have different characteristics as compared to the IMFs. The systematic
variation of the LP emission cross section $\sigma_{LP}$, and IMF emission
cross section $\sigma_{IMF}$, calculated on the present DCM match exactly the
statistical fission model predictions. It is for the first time that a
non-statistical dynamical description is developed for the emission of
light-particles from the hot and rotating CN. The model is applied to the decay
of $^{56}$Ni formed in the $^{32}$S + $^{24}$Mg reaction at two incident
energies E$_{c.m.}$ = 51.6 and 60.5 MeV. Both the IMFs and average $\bar{TKE}$
spectra are found to compare reasonably nicely with the experimental data,
favoring asymmetric mass distributions. The LPs emission cross section is shown
to depend strongly on the type of emitted particles and their multiplicities.


title:
Spinodal decomposition, nuclear fog and two characteristic volumes in
  thermal multifragmentation

abstract:
  Thermal multifragmentation of hot nuclei is interpreted as the nuclear
liquid-fog phase transition inside the spinodal region. The experimental data
for p(8.1GeV) + Au collisions are analyzed within the framework of the
statistical multifragmentation model (SMM) for the events with emission of at
least two IMFs. It is found that the partition of hot nuclei is specified after
expansion to a volume equal to Vt = (2.6+-0.3) Vo, with Vo as the volume at
normal density. However, the freeze-out volume is found to be twice as large:
Vf = (5+-1) Vo.


title: Critical Behavior in Light Nuclear Systems: Experimental Aspects

abstract:
  An extensive experimental survey of the features of the disassembly of a
small quasi-projectile system with $A \sim$ 36, produced in the reactions of 47
MeV/nucleon $^{40}$Ar + $^{27}$Al, $^{48}$Ti and $^{58}$Ni, has been carried
out. Nuclei in the excitation energy range of 1-9 MeV/u have been investigated
employing a new method to reconstruct the quasi-projectile source. At an
excitation energy $\sim$ 5.6 MeV/nucleon many observables indicate the presence
of maximal fluctuations in the de-excitation processes. The fragment
topological structure shows that the rank sorted fragments obey Zipf's law at
the point of largest fluctuations providing another indication of a liquid gas
phase transition. The caloric curve for this system shows a monotonic increase
of temperature with excitation energy and no apparent plateau. The temperature
at the point of maximal fluctuations is $8.3 \pm 0.5$ MeV. Taking this
temperature as the critical temperature and employing the caloric curve
information we have extracted the critical exponents $\beta$, $\gamma$ and
$\sigma$ from the data. Their values are also consistent with the values of the
universality class of the liquid gas phase transition. Taken together, this
body of evidence strongly suggests a phase change in an equilibrated mesoscopic
system at, or extremely close to, the critical point.


title: Radioactive Ion Beam Physics and Nuclear Astrophysics in China

abstract:
  Based on the intermediate energy radioactive Ion Beam Line in Lanzhou (RIBLL)
of Heavy Ion Research Facility in Lanzhou (HIRFL) and Low Energy Radioactive
Ion Beam Line (GIRAFFE) of Beijing National Tandem Accelerator Lab (HI13), the
radioactive ion beam physics and nuclear astrophysics will be researched in
detail. The key scientific problems are: the nuclear structure and reaction for
nuclear far from $\beta$-stability line; the synthesize of new nuclides near
drip lines and new super heavy nuclides; the properties of asymmetric nuclear
matter with extra large isospin and some nuclear astro- reactions.


title:
Quark Gluon Plasma an Color Glass Condensate at RHIC? The perspective
  from the BRAHMS experiment

abstract:
  We review the main results obtained by the BRAHMS collaboration on the
properties of hot and dense hadronic and partonic matter produced in
ultrarelativistic heavy ion collisions at RHIC. A particular focus of this
paper is to discuss to what extent the results collected so far by BRAHMS, and
by the other three experiments at RHIC, can be taken as evidence for the
formation of a state of deconfined partonic matter, the so called
quark-gluon-plasma (QGP). We also discuss evidence for a possible precursor
state to the QGP, i.e. the proposed Color Glass Condensate.

YAG:Nd crystals as possible detector to search for double beta and alpha
  decay of neodymium

abstract:
  Energy resolution, alpha/beta ratio, pulse-shape discrimination for gamma
rays and alpha particles, radioactive contamination were studied with neodymium
doped yttrium-aluminum garnet (YAG:Nd). Applicability of YAG:Nd scintillators
to search for double beta decay and alpha activity of natural neodymium
isotopes are discussed.


title: The PHOBOS Perspective on Discoveries at RHIC

abstract:
  This paper describes the conclusions that can be drawn from the data taken
thus far with the PHOBOS detector at RHIC. In the most central Au+Au collisions
at the highest beam energy, evidence is found for the formation of a very high
energy density system whose description in terms of simple hadronic degrees of
freedom is inappropriate. Furthermore, the constituents of this novel system
are found to undergo a significant level of interaction. The properties of
particle production at RHIC energies are shown to follow a number of simple
scaling behaviors, some of which continue trends found at lower energies or in
simpler systems. As a function of centrality, the total number of charged
particles scales with the number of participating nucleons. When comparing
Au+Au at different centralities, the dependence of the yield on the number of
participants at higher pT (~4 GeV/c) is very similar to that at low transverse
momentum. The measured values of charged particle pseudorapidity density and
elliptic flow were found to be independent of energy over a broad range of
pseudorapidities when effectively viewed in the rest frame of one of the
colliding nuclei, a property we describe as "extended longitudinal scaling''.
Finally, the centrality and energy dependences of several observables were
found to factorize to a surprising degree.


title:
Observation of the lowest energy gamma-ray in any superdeformed nucleus
  : 196Bi

abstract:
  New results on the superdeformed $^{196}$Bi nucleus a re reported. We have
observed with the EUROBALL IV $\gamma$-ray spectrometer array a superdeformed
trans ition of 124 keV which is the lowest observed energy $\gamma$-ray in any
superdeformed nucleus. We have de velopped microscopic cranked
Hartree-Fock-Bogoliubov calculations using the SLy4 effective force and a
realistic surface p airing which strongly support the
$K^\pi=2^-$($\pi$[651]1/2$\otimes \nu$[752]5/2) assignment of this su
perdeformed band.


title: The nuclear liquid gas phase transition and phase coexistence: A review

abstract:
  In this talk we will review the different signals of liquid gas phase
transition in nuclei. From the theoretical side we will first discuss the
foundations of the concept of equilibrium, phase transition and critical
behaviors in infinite and finite systems. From the experimental point of view
we will first recall the evidences for some strong modification of the behavior
of hot nuclei. Then we will review quantitative detailed analysis aiming to
evidence phase transition, to define its order and phase diagram. Finally, we
will present a critical discussion of the present status of phase transitions
in nuclei and we will draw some lines for future development of this field.


title:
Design Constraints for a WIMP Dark Matter and pp Solar Neutrino Liquid
  Neon Scintillation Detector

abstract:
  Detailed Monte-Carlo simulations were used to evaluate the performance of a
liquid neon scintillation detector for dark matter and low-energy solar
neutrino interactions. A maximum-likelihood event vertex fitter including PMT
time information was developed, which significantly improves position
resolution over spatial-only algorithms, and substantially decreases the
required detector size and achievable analysis energy threshold. The ultimate
sensitivity to WIMP dark matter and the pp flux uncertainty are evaluated as a
function of detector size. The dependence on the neon scintillation and PMT
properties are evaluated. A 300 cm radius detector would allow a ~13 keV
threshold, a pp flux uncertainty of ~1%, and limits on the spin-independent
WIMP-nucleon cross-section of ~10^{-46} cm^2 for a 100 GeV WIMP, using
commercially available PMTs. Detector response calibration and background
requirements for a precision pp measurement are defined. Internal radioactivity
requirements for uranium, thorium, and krypton are specified, and it is shown
that the PMT data could be used for an in-situ calibration of the troublesome
krypton-85. A set of measurements of neon scintillation properties and PMT
characteristics are outlined which will be needed in order to evaluate
feasibility and fully optimize the design of a neon-based detector.

Measurement of the Electric Form Factor of the Neutron at Q^2 = 0.3-0.8
  (GeV/c)^2

abstract:
  The electric form factor of the neutron, G_En, has been measured at the Mainz
Microtron by recoil polarimetry in the quasielastic D(e_pol,e'n_pol)p reaction.
Three data points have been extracted at squared four-momentum transfers Q^2 =
0.3, 0.6 and 0.8 (GeV/c)^2. Corrections for nuclear binding effects have been
applied.


title:
Measurement of R = sigma_L / sigma_T and the Separated Longitudinal and
  Transverse Structure Functions in the Nucleon Resonance Region

abstract:
  We report on a detailed study of longitudinal strength in the nucleon
resonance region, presenting new results from inclusive electron-proton cross
sections measured at Jefferson Lab Hall C in the four-momentum transfer range
0.2 < Q^2 < 5.5 GeV^2. The data have been used to accurately perform 167
Rosenbluth-type longitudinal / transverse separations. The precision R =
sigma_L / sigma_T data are presented here, along with the first separate values
of the inelastic structure functions F_1 and F_L in this regime. The resonance
longitudinal component is found to be significant, both in magnitude and in the
existence of defined mass peaks. Additionally, quark-hadron duality is here
observed above Q^2 = 1 GeV^2 in the separated structure functions
independently.


title: Q^2 Evolution of Generalized Baldin Sum Rule for the Proton

abstract:
  The generalized Baldin sum rule for virtual photon scattering, the
unpolarized analogy of the generalized Gerasimov-Drell-Hearn integral, provides
an important way to investigate the transition between perturbative QCD and
hadronic descriptions of nucleon structure. This sum rule requires integration
of the nucleon structure function F_1, which until recently had not been
measured at low Q^2 and large x, i.e. in the nucleon resonance region. This
work uses new data from inclusive electron-proton scattering in the resonance
region obtained at Jefferson Lab, in combination with SLAC deep inelastic
scattering data, to present first precision measurements of the generalized
Baldin integral for the proton in the Q^2 range of 0.3 to 4.0 GeV^2.


title: Recent advances in neutrinoless double beta decay search

abstract:
  Even after the discovery of neutrino flavour oscillations, based on data from
atmospheric, solar, reactor, and accelerator experiments, many characteristics
of the neutrino remain unknown. Only the neutrino square-mass differences and
the mixing angle values have been estimated, while the value of each mass
eigenstate still hasn't. Its nature (massive Majorana or Dirac particle) is
still escaping. Neutrinoless double beta decay ($0\nu$-DBD) experimental
discovery could be the ultimate answer to some delicate questions of elementary
particle and nuclear physics. The Majorana description of neutrinos allows the
$0\nu$-DBD process, and consequently either a mass value could be measured or
the existence of physics beyond the standard should be confirmed without any
doubt. As expected, the $0\nu$-DBD measurement is a very difficult field of
application for experimentalists. In this paper, after a short summary of the
latest results in neutrino physics, the experimental status, the R&D projects,
and perspectives in $0\nu$-DBD sector are reviewed.


title: Directed and elliptic flow in Au + Au at intermediate energies

abstract:
  Directed and elliptic flow for the Au + Au system at incident energies
between 40 and 150 MeV per nucleon has been measured using the INDRA 4 pi
multi-detector. For semi-central collisions, the elliptic flow of Z <= 2
particles switches from in-plane to out-of-plane enhancement at around 100 MeV
per nucleon, in good agreement with the result reported by the FOPI
Collaboration. The directed flow changes sign at a bombarding energy between 50
and 60 MeV per nucleon and remains negative at lower energies. The conditions
for the appearance and possible origins of negative flow are discussed.


title: Do We Accurately Know the Formation of Solar 8B?

abstract:
  A detailed examination of current data on S_17 (as opposed to an examination
of S_17(0) only) excludes quoting S_17(0) with sufficiently small uncertainty.
In contrast to suggestions that S_17(0) is now known with the accuracy of \pm
3%, the exact value of S_17(0) is dependent on the choice of the data and the
choice of theory used for extrapolation. In addition recent high precision
results (including the Seattle data) on S_17 which are in good agreement, still
differ on the measured slopes, as do theoretical models that predict different
d-wave contribution, precluding an accurate extrapolation to zero energy of the
consistent data. Using a common extrapolation of only the consistent high
precision data, suggests a value of S_17(0) = 21.2 \pm 0.5 eV-b, but a value
equal to or smaller than 19.0 eV-b can not be excluded due to the uncertainty
in the extrapolation, leading to an additional error of +0.0 -3.0 eV-b. This
(unacceptable) situation must be cleared by future experiments.


title:
Inclusive pi0 spectra at high transverse momentum in d-Au collisions at
  RHIC

abstract:
  Preliminary results on inclusive neutral pion production in d-Au collisions
at sqrt(s_NN) = 200 GeV in the pseudo-rapidity range 0<eta<1 are presented. The
measurement is performed using the STAR Barrel Electromagnetic calorimeter
(BEMC). In this paper, the analysis of the first BEMC hadron measurement is
described and the results are compared with earlier RHIC findings. The pi0
invariant differential cross sections show good agreement with next-to-leading
order (NLO) perturbative QCD calculations.


title: High pT hadron spectra at RHIC: an overview

abstract:
  Recent results on high transverse momentum (pT) hadron production in p+p,
d+Au and Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) are
reviewed. Comparison of the nuclear modification factors, $R_{dAu}(pT)$ and
$R_{AA}(pT)$, demonstrates that the large suppression in central Au+Au
collisions is due to strong final-state effects. Theoretical models which
incorporate jet quenching via gluon Bremsstrahlung in the dense partonic medium
that is expected in central Au+Au collisions at ultra-relativistic energies are
shown to reproduce the shape and magnitude of the observed suppression over the
range of collision energies so far studied at RHIC.


title:
Strange particle production in 158 and 40 $A$ GeV/$c$ Pb-Pb and p-Be
  collisions

abstract:
  Results on strange particle production in Pb-Pb collisions at 158 and 40 $A$
GeV/$c$ beam momentum from the NA57 experiment at CERN SPS are presented.
Particle yields and ratios are compared with those measured at RHIC.
Strangeness enhancements with respect to p-Be reactions at the same beam
momenta have been also measured: results about their dependence on centrality
and collision energy are reported and discussed.


title:
Structure and Fine Structure in Multiparticle Production Data at High
  Energies

abstract:
  A summary is given of data on the longitudinal rapidity and pseudorapidity
distributions observed in $e^+e^-$, pp, pA and AA collisions at high energies.
The remarkable simplicity and universality observed in the data and its
relevance to the study of the high energy density system produced in heavy ion
collisions is discussed.


title: Branching ratio measurements of the 7.12-MeV state in 16O

abstract:
  Knowledge of the gamma-ray branching ratios of the 7.12-MeV state of 16O is
important for the extrapolation of the 12C(a,g)16O cross section to
astrophysical energies. Ground state transitions provide most of the
12C(a,g)16O total cross section while cascade transitions have contributions of
the order of 10-20%. Determining the 7.12-MeV branching ratio will result in a
better extrapolation of the cascade and E2 ground state cross section to low
energies. We report here on measurements on the branching ratio of the 7.12-MeV
level in 16O.


title: 49Cr: Towards full spectroscopy up to 4 MeV

abstract:
  The nucleus 49Cr has been studied analysing gamma-gamma coincidences in the
reaction 46Ti(alpha,n)49Cr at the bombarding energy of 12 MeV. The level scheme
has been greatly extended at low excitation energy and several new lifetimes
have been determined by means of the Doppler Shift Attenuation Method.
  Shell model calculations in the full pf configuration space reproduce well
negative-parity levels. Satisfactory agreement is obtained for positive parity
levels by extending the configuration space to include a nucleon-hole either in
the 1d3/2 or in the 2s1/2 orbitals.
  A nearly one-to-one correspondence is found between experimental and
theoretical levels up to an excitation energy of 4 MeV.
  Experimental data and shell model calculations are interpreted in terms of
the Nilsson diagram and the particle-rotor model, showing the strongly coupled
nature of the bands in this prolate nucleus. Nine values of K(pi) are proposed
for the levels observed in this experiment.
  As a by-result it is shown that the values of the experimental magnetic
moments in 1f7/2 nuclei are well reproduced without quenching the nucleon
g-factors.


title: Open Charm Production at STAR

abstract:
  We present the open charm spectra at mid-rapidity from direct reconstruction
of D0, D* and D+/- in d+Au collisions at sqrt(sNN)=200 GeV using the STAR
detector at RHIC. The indirect electron/positron measurements via charm
semileptonic decays in p+p and d+Au collisions are also reported. The total
c\bar(c) cross section per nucleon-nucleon collision is extracted from both
direct and indirect measurements and are consistent with each other. By
combining the D0 and semileptonic measurements together, the cross section of
1.4+/-0.2+/-0.4 mb is higher than expectations from PYTHIA and other pQCD
calculations. The open charm pT distribution from direct measurements covers
the pT range up to ~10 GeV/c and follows a power-law distribution.


title: Sigma(1385) Results and Status of the Theta^{+} in STAR

abstract:
  The Sigma(1385) analysis and the current status of pentaquark search with the
STAR detector are reported. The corrected p_{T} spectra and the yields of the
Sigma ^{\pm}(1385) and their antiparticles in the most central Au+Au as well as
elementary p+p collisions are presented. A comparison of the <p_{T}> of
observed particles suggests a similar behavior for particles with mass greater
than 1.2 GeV in p+p and Au+Au collision environments. Acceptance and efficiency
studies with simulations show that the (anti)pentaquarks should be found at the
3% level.


title: Reeconstructing Sigma0 decays in STAR

abstract:
  Typical comparisons of data from nuclear collisions to particle production
models require a caveat for (anti)Lambda yields from experimental inability to
separate the contributions of those yields from Sigma state decays. Recent
analysis in STAR is leading toward resolving the contribution from excited
Sigma states, but the bulk contribution comes from electromagnetic decays of
the (anti)Sigma0.
  In the STAR detector, photon conversions into e+e- pairs in the detector
material have been used to identify photons from pi0 decays. A similar
technique has been used here to identify photons from (anti)Sigma0 decays in
conjunction with STAR's excellent PID capabilities for finding the associated
(anti)Lambda daughters. We report here on progress toward measuring the
(anti)Sigma0 yields in various nuclear collisions at RHIC.


title: Indications for the onset of deconfinement in nucleus nucleus collisions

abstract:
  The hadronic final state of central Pb+Pb collisions at 20, 30, 40, 80, and
158 AGeV has been measured by the CERN NA49 collaboration. The mean transverse
mass of pions and kaons at midrapidity stays nearly constant in this energy
range, whereas at lower energies, at the AGS, a steep increase with beam energy
was measured. Compared to p+p collisions as well as to model calculations,
anomalies in the energy dependence of pion and kaon production at lower SPS
energies are observed. These findings can be explained, assuming that the
energy density reached in central A+A collisions at lower SPS energies is
sufficient to transform the hot and dense nuclear matter into a deconfined
phase.


title: Precision muon lifetime and capture experiments at PSI

abstract:
  The muLan experiment at the Paul Scherrer Institute will measure the lifetime
of the positive muon with a precision of 1 ppm, giving a value for the Fermi
coupling constant G_F at the level of 0.5 ppm. Meanwhile, by measuring the
observed lifetime of the negative muon in pure hydrogen, the muCap experiment
will determine the rate of muon capture, giving the proton's pseudoscalar
coupling g_p to 7%. This coupling can be calculated precisely from heavy baryon
chiral perturbation theory and therefore permits a test of QCD's chiral
symmetry.


title:
Tensor analyzing power Ayy in deuteron inclusive breakup at large Pt and
  spin structure of deuteron at short internucleonic distances

abstract:
  The Ayy data for deuteron inclusive breakup off hydrogen and carbon at a
deuteron momentum of 9.0 GeV/c and large Pt of emitted protons are presented.
The large values of Ayy independent of the target mass reflect the sensitivity
of the data to the deuteron spin structure. The data obtained at fixed $x$ and
plotted versus Pt clearly demonstrate the dependence of the deuteron spin
structure at short internucleonic distances on two variables. The data are
compared with the calculations using Paris, CD-Bonn and Karmanov's deuteron
wave functions.


title: Mass and Isospin Effects in Multifragmentation

abstract:
  A systematic study of isospin effects in the breakup of projectile spectators
at relativistic energies has been performed with the ALADiN spectrometer at the
GSI laboratory (Darmstadt). Four different projectiles 197Au, 124La, 124Sn and
107Sn, all with an incident energy of 600 AMeV, have been used, thus allowing a
study of various combinations of masses and N/Z ratios in the entrance channel.
The measurement of the momentum vector and of the charge of all projectile
fragments with Z>1 entering the acceptance of the ALADiN magnet has been
performed with the high efficiency and resolution achieved with the TP-MUSIC IV
detector. The Rise and Fall behavior of the mean multiplicity of IMFs as a
function of Zbound and its dependence on the isotopic composition has been
determined for the studied systems. Other observables investigated so far
include mean N/Z values of the emitted light fragments and neutron
multiplicities. Qualitative agreement has been obtained between the observed
gross properties and the predictions of the Statistical Multifragmentation
Model.


title:
Centrality and Transverse Momentum Dependence of Collective Flow in 158
  A GeV Pb+Pb Collisions Measured via Inclusive Photons

abstract:
  Directed and elliptic flow of inclusive photons near mid-rapidity in $158 $A
GeV Pb+Pb collisions has been studied. The data have been obtained with the
photon spectrometer LEDA of the WA98 experiment at the CERN SPS.
  The flow strength has been measured for various centralities as a function of
$p_T$ and rapidity over $0.18 < p_T < 1.5 \mathrm{GeV}/c$ and $2.3 < y < 2.9$.
The angular anisotropy has been studied relative to an event plane obtained in
the target fragmentation region that shows the elliptic flow to be in-plane.
The elliptic flow has also been studied using two-particle correlations and
shown to give similar results. A small directed flow component is observed.
Both the directed and elliptic flow strengths increase with $p_T$. The photon
flow results are used to estimate the corresponding neutral pion flow.


title: Charged Pion Spectra in Au+Au Collisions at \srt=62.4 GeV

abstract:
  The combination of the ionization energy loss (dE/dx) from Time Projection
Chamber (TPC) at $\simeq8$% resolution and multi-gap resistive plate chamber
time-of-flight (TOF) at 85$ps$ provides powerful particle identification. We
present spectra of identified charged pions from transverse momentum
$p_T\simeq0.2$ GeV/c to ~7-8 GeV/c in Au+Au collisions at
$\sqrt{s_{_{NN}}}=62.4$ GeV. Physics implications will be discussed.


title:
How does breakup influence near-barrier fusion of weakly bound light
  nuclei ?

abstract:
  The influence on the fusion process of coupling to collective degrees of
freedom has been explored. The significant enhancement of he fusion cross
setion at sub-barrier energies was understood in terms of the dynamical
processes arising from strong couplings to collective inelastic excitations of
the target and projectile. However, in the case of reactions where breakup
becomes an important process, conflicing model predictions and experimental
results have been reported in the literature. Excitation functions for sub- and
near-barrier total (complete + incomplete) fusion cross sections have been
measured for the $^{6,7}$Li + $^{59}$Co at the Vivitron facility and at the 8UD
Pelletron tandem facility using standard $\gamma$-ray techniques. The data
extend to medium-mass systems previous works exploring the coupling effects in
fusion reactions of both lighter and heavier systems. Results of
continuum-discretized coupled channel (CDCC) calculations indicate a small
enhancement of total fusion for the more weakly bound $^{6}$Li at sub-barrier
energies, with similar cross sections for both reactions at and above the
barrier. A systematic study of $^{4,6}$He induced fusion reactions with the
CDCC method is in progress. The understanding of the reaction dynamics
involving couplings to the breakup channels requires th explicit measurement of
precise elastic scattering data as well as yields leading to the breakup
itself. Recent coincidence experiments for $^{6,7}$Li + $^{59}$Co are
addressing this issue. The particle identification of the breakup products have
been achieved by measuring the three-body final-state correlations.


title:
Minijet deformation and charge-independent angular correlations on
  momentum subspace $(\eta,\phi)$ in Au-Au collisions at $\sqrt{s_{NN}}$ = 130
  GeV

abstract:
  First measurements of charge-independent correlations on angular difference
variables $\eta_1 - \eta_2$ (pseudorapidity) and $\phi_1 - \phi_2$ (azimuth)
are presented for primary charged hadrons with transverse momentum $0.15 \leq
p_t \leq 2$ GeV/$c$ and $|\eta| \leq 1.3$ from Au-Au collisions at
$\sqrt{s_{NN}} = 130$ GeV. Strong charge-independent angular correlations are
observed associated with jet-like structures and elliptic flow. The width of
the jet-like peak on $\eta_1 - \eta_2$ increases by a factor 2.3 from
peripheral to central collisions, suggesting strong coupling of semi-hard
scattered partons to a longitudinally-expanding medium. New methods of jet
analysis introduced here provide evidence for nonperturbative QCD medium
effects in heavy ion collisions.


title:
Two-Phase Emission Detector for Measuring Coherent Neutrino-Nucleus
  Scattering

abstract:
  Coherent scattering is a flavor-blind, high-rate, as yet undetected neutrino
interaction predicted by the Standard Model. We propose to use a compact
(kg-scale), two-phase (liquid-gas) argon ionization detector to measure
coherent neutrino scattering off nuclei. In our approach, neutrino-induced
nuclear recoils in the liquid produce a weak ionization signal, which is
transported into a gas under the influence of an electric field, amplified via
electroluminescence, and detected by phototubes or avalanche diodes. This paper
describes the features of the detector, and estimates signal and background
rates for a reactor neutrino source. Relatively compact detectors of this type,
capable of detecting coherent scattering, offer a new approach to flavor-blind
detection of man-made and astronomical neutrinos, and may allow development of
compact neutrino detectors capable of non-intrusive real-time monitoring of
fissile material in reactors.


title: Towards the critical behavior for the light nuclei by NIMROD detector

abstract:
  The critical behavior for the light nuclei with A$\sim 36$ has been
investigated experimentally by the NIMROD multi-detectors. The wide variety of
observables indicate the critical point has been reached in the disassembly of
hot nuclei at an excitation energy of 5.6$\pm$0.5 MeV/u.


title: Parallel momentum distribution of the $^{28}$Si fragments from $^{29}$P

abstract:
  Distribution of the parallel momentum of $^{28}$Si fragments from the breakup
of 30.7 MeV/nucleon $^{29}$P has been measured on C targets. The distribution
has the FWHM with the value of 110.5 $\pm$ 23.5 MeV/c which is consistent
quantitatively with Galuber model calculation assuming by a valence proton in
$^{29}$P. The density distribution is also predicted by Skyrme-Hartree-Fock
calculation. Results show that there might exist the proton-skin structure in
$^{29}$P.


title: Single Electron Elliptic Flow Measurements in Au+Au Collisions from STAR

abstract:
  Recent measurements of elliptic flow (v_2) and the nuclear modification
factor (R_{CP}) of strange mesons and baryons in the intermediate p_T domain in
Au+Au collisions demonstrate a scaling with the number of constituent-quarks.
This suggests hadron production via quark coalescence from a thermalized parton
system. Measuring the elliptic flow of charmed hadrons, which are believed to
originate rather from fragmentation than from coalescence processes, might
therefore change our view of hadron production in heavy ion collisions.
  While direct v_2 measurements of charmed hadrons are currently not available,
single electron v_2 at sufficiently high transverse momenta can serve as a
substitute. At transverse momenta above 2 GeV/c, the production of single
electrons from non-photonic sources is expected to be dominated by the decay of
charmed hadrons. Simulations show a strong correlation between the flow of the
charmed hadrons and the flow of their decay electrons for p_T > 2 GeV/c.
  We will present preliminary STAR results from our single electron v_2
measurements from Au+Au collisions at RHIC energies.


title:
Possible Indication of Narrow Baryonic Resonances Produced in the
  1720-1790 MeV Mass Region

abstract:
  Signals of two narrow structures at M=1747 MeV and 1772 MeV were observed in
the invariant masses M_{pX} and M_{\pi^{+}X} of the pp->ppX and pp->p\pi^{+}X
reactions respectively. Many tests were made to see if these structures could
have been produced by experimental artefacts. Their small widths and the
stability of the extracted masses lead us to conclude that these structures are
genuine and may correspond to new exotic baryons. Several attempts to identify
them, including the possible "missing baryons" approach, are discussed.


title: Surface and volume effects in the photoabsorption of nuclei

abstract:
  Recent experimental results for meson photoproduction from nuclei obtained
with TAPS at MAMI are analyzed in view of the suppression of the second nucleon
resonance region in total photoabsorption. The cross sections can be split into
a component from the low density surface region of nuclei and a component which
scales more like the nuclear volume. The energy dependence of the surface
component is similar to the deuteron cross section, it shows a clear signal for
the second resonance peak assigned to the excitation of the P11(1440),
D13(1520), and S11(1535). The volume component behaves differently, it is
lacking the second resonance peak and shows an enhancement at intermediate
photon energies.


title: Hadron Production at Intermediate $p_T$ at RHIC

abstract:
  Large proton and antiproton enhancement with respect to pions has been
observed at intermediate transverse momentum $p_T \approx$ 2-5 GeV/$c$ in Au+Au
collisions at RHIC. To investigate the possible source of this anomaly, the
production of $\phi$ mesons and two particle angular correlations triggered by
mid-$p_T$ baryons or mesons are studied. We also present the first measurement
of proton and antiproton production at $\sqrt{s_{NN}} = 62.4$ GeV in Au+Au
collisions, which aims to study the energy dependence of the observed baryon
enhancement.

Determination of the Gamow-Teller Quenching Factor from Charge Exchange
  Reactions on 90Zr

abstract:
  Double differential cross sections between 0-12 degrees were measured for the
90Zr(n,p) reaction at 293 MeV over a wide excitation energy range of 0-70 MeV.
A multipole decomposition technique was applied to the present data as well as
the previously obtained 90Zr(p,n) data to extract the Gamow-Teller (GT)
component from the continuum. The GT quenching factor Q was derived by using
the obtained total GT strengths. The result is Q=0.88+/-0.06 not including an
overall normalization uncertainty in the GT unit cross section of 16%.


title: Studies of multiplicity in relativistic heavy-ion collisions

abstract:
  In this talk I'll review the present status of charged particle multiplicity
measurements from heavy-ion collisions. The characteristic features of
multiplicity distributions obtained in Au+Au collisions will be discussed in
terms of collision centrality and energy and compared to those of p+p
collisions. Multiplicity measurements of d+Au collisions at 200 GeV
nucleon-nucleon center-of-mass energy will also be discussed. The results will
be compared to various theoretical models and simple scaling properties of the
data will be identified.


title:
High Resolution Search for Exotic Pentaquark $\Theta^{++}$, and
  $\Theta^+$ at Jefferson Lab

abstract:
  Recent evidence for the existence of pentaquark $\Theta^+$ particle from
several experiments at several different laboratories around the world has
caused great excitement and raised many unanswered questions. We discuss a new
proposal on a high resolution experiment searching for pentaquark states in
Hall C at Jefferson Lab using an untagged bremsstrahlung photon beam employing
both the hydrogen and the deuterium targets by studying the following
processes: $\gamma p \to \Theta^{++} K^-$, and $\gamma n \to \Theta^+ K^-$.
This new experiment will significantly improve our current knowledge of the
mass, the width of the $\Theta^+$ particle if it is confirmed and provide
unambiguous evidence for the existence or non-existence of the $\Theta^{++}$
particle from the \gamma p \to \Theta^{++} K^-$ process.


title: Pion photoproduction on the nucleon

abstract:
  The $\gamma n \to \pi^- p$ and $\gamma p \to \pi^+ n$ reactions are essential
probes of the transition from meson-nucleon degrees of freedom to quark-gluon
degrees of freedom in exclusive processes. The cross sections of these
processes are also advantageous, for the investigation of oscillatory behavior
around the quark counting prediction, since they decrease relatively slower
with energy compared with other photon-induced processes. In this talk, we
discuss recent results on the $\gamma p \to \pi^+ n$ and $\gamma n \to
\pi^{-}p$ processes from Jefferson Lab experiment E94-104. We also discuss a
new experiment in which singles $\gamma p \to \pi^+ n$ measurement from
hydrogen, and coincidence $\gamma n \to \pi^{-} p$ measurements at the
quasifree kinematics from deuterium for center-of-mass energies between 2.3 GeV
to 3.4 GeV in fine steps at a center-of-mass angle of $90^\circ$ are planned.
The proposed measurement will allow a detailed investigation of the oscillatory
scaling behavior in photopion production processes.


title: Neutron Electromagnetic Form Factors

abstract:
  The nucleon electromagnetic form factors have been studied in the past
extensively from unpolarized electron scattering experiments. With the
development in polarized beam, recoil polarimetry, and polarized target
technologies, polarization experiments have provided more precise data on these
quantities. In this talk, I review recent experimental progress on this
subject.


title:
phi photo-production from Li, C, Al, and Cu nuclei at Egamma=1.5 - 2.4
  GeV

abstract:
  The photo-production of $\phi$ mesons from Li, C, Al, and Cu at forward
angles has been measured at $E_gamma$=1.5--2.4 GeV. The number of events for
incoherent phi photo-production is found to have a target mass number
dependence of $A^{0.72\pm 0.07}$ in the kinematical region of $|t|\le 0.6$
${\rm GeV}^2/c^2$. The total cross section of the $\phi$-nucleon interaction,
$\sigma_{\phi N}$, has been estimated as $35^{+17}_{-11}$ mb using the
$A$-dependence of the $\phi$ photo-production yield and a Glauber-type multiple
scattering theory. This value is much larger than $\sigma_{\phi N}$ in free
space, suggesting that the $\phi$ properties might change in the nuclear
medium.


title:
Response to the IUPAC/IUPAP Joint Working Party Second Report 'On the
  Discovery of Elements 110-118'

abstract:
  Back in 1971 fission fragments were observed by us in Hg sources separated
from two CERN W targets that were irradiated with 24 GeV protons. The masses of
the fissioning species were measured and heavy masses like 272, 308 and 317-318
were found and interpreted as due to the superheavy element 112 with 160-161
neutrons and various molecules of it. Based on the measured mass of the
produced superheavy nucleus cold fusion reactions like 88Sr + 184W -> 272(112)
and 86Sr + 186W -> 272(112) were deduced. The ordinary heavy ion reaction 88Sr
+ 184W has been studied and characteristic X-rays of element 112 and a very
high-energy alpha particle in coincidence with a fission fragment have been
observed. The data have been studied by the TWG and they were concerned about
the question of the reaction mechanism since very large fusion cross sections,
in the region of a few mb, have been deduced in the secondary reaction
experiments. This question can now be answered in view of our recent discovery
of long-lived super- and hyperdeformed isomeric states. The JWP did not accept
our arguments and this response answers their queries.


title:
Nucleon-nucleon coincidence measurement in the non-mesonic weak decay of
  5_Lambda-He and 12_Lambda-C hypernuclei

abstract:
  We have measured both yields of neutron-proton and neutron-neutron pairs
emitted from the non-mesonic weak decay process of 5_Lambda-He and 12_Lambda-C
hypernuclei produced via the (pi^+,K^+) reaction for the first time. We
observed clean back-to-back correlation of the np- and nn-pairs in the
coincidence spectra for both hypernuclei. The ratio of those back-to-back pair
yields, Nnn / Nnp, must be close to the ratio of neutron- and proton-induced
decay widths of the decay, Gn(Lambda n -> nn)/Gp(Lambda p -> np). The obtained
ratios for each hypernuclei support recent calculations based on short-range
interactions.


title:
Analyzing Powers and Spin Correlation Coefficients for p+d Elastic
  Scattering at 135 and 200 MeV

abstract:
  The proton and deuteron analyzing powers and 10 of the possible 12 spin
correlation coefficients have been measured for p+d elastic scattering at
proton bombarding energies of 135 and 200 MeV. The results are compared with
Faddeev calculations using two different NN potentials. The qualitative
features of the extensive data set on the spin dependence in p+d elastic
scattering over a wide range of angles presented here are remarkably well
explained by two-nucleon force predictions without inclusion of a three-nucleon
force. The remaining discrepancies are, in general, not alleviated when
theoretical three-nucleon forces are included in the calculations.


title:
Investigation of the Angular Dependence of the Tensor Analyzing Power of
  9 Gev/C Deuteron Breakup

abstract:
  An angular dependence of the tensor analyzing power of the breakup of
polarized deuterons at 9 GeV/$c$ has been investigated. The measurements have
been made on hydrogen and carbon targets at angles in the range from 85 to 160
mr. The data obtained are analyzed within the framework of the light-front
dynamics using the deuteron wave functions for Paris and Bonn CD potentials,
and the relativistic deuteron wave function by Karmanov et al. The experimental
data are in rough agreement with calculations with the use of Karmanov's
deuteron wave function.


title:
Observation of different azimuthal emission patterns for K+ and of K-
  mesons in Heavy Ion Collisions at 1-2 AGeV

abstract:
  Azimuthal distributions of pi+, K+ and K- mesons have been measured in Au+Au
reactions at 1.5 AGeV and Ni+Ni reactions at 1.93 AGeV. In semi-central
collisions at midrapidity, pi+ and K+ mesons are emitted preferentially
perpendicular to the reaction plane in both collision systems. In contrast for
K- mesons in Ni+Ni reactions an in-plane elliptic flow was observed for the
first time at these incident energies.


title: A Current Mode Detector Array for Gamma-Ray Asymmetry Measurements

abstract:
  We have built a CsI(Tl) gamma-ray detector array for the NPDGamma experiment
to search for a small parity-violating directional asymmetry in the angular
distribution of 2.2 MeV gamma-rays from the capture of polarized cold neutrons
by protons with a sensitivity of several ppb. The weak pion-nucleon coupling
constant can be determined from this asymmetry. The small size of the asymmetry
requires a high cold neutron flux, control of systematic errors at the ppb
level, and the use of current mode gamma-ray detection with vacuum photo diodes
and low-noise solid-state preamplifiers. The average detector photoelectron
yield was determined to be 1300 photoelectrons per MeV. The RMS width seen in
the measurement is therefore dominated by the fluctuations in the number of
gamma rays absorbed in the detector (counting statistics) rather than the
intrinsic detector noise. The detectors were tested for noise performance,
sensitivity to magnetic fields, pedestal stability and cosmic background. False
asymmetries due to gain changes and electronic pickup in the detector system
were measured to be consistent with zero to an accuracy of $10^{-9}$ in a few
hours. We report on the design, operating criteria, and the results of
measurements performed to test the detector array.


title:
Multifragmentation and the liquid-gas phase transition: an experimental
  overview

abstract:
  Two roads are presently being followed in order to establish the existence of
a liquid-gas phase transition in finite nuclear systems from nuclear reactions
at high energy. The clean experiment of observing the thermodynamic properties
of a finite number of nucleons in a container is presently only possible with
the computer. Performed with advanced nuclear transport models, it has revealed
the first-order character of the transition and allowed the extraction of the
pertinent thermodynamic parameters. The validity of the applied theory is being
confirmed by comparing its predictions for heavy-ion reactions with exclusive
experiments.
  The second approach is experimentally more direct. Signals of the transition
are searched for by analysing reaction data within the framework of
thermodynamics of small systems. A variety of potential signals has been
investigated and found to be qualitatively consistent with the expectations for
the phase transition. Many of them are well reproduced with percolation models
which places the nuclear fragmentation into the more general context of
partitioning phenomena in finite systems.
  A wealth of new data on this subject has been obtained in recent experiments,
some of them with a new generation of multi-detector devices aiming at higher
resolutions, isotopic identification of the fragments, and the coincident
detection of neutrons. Isotopic effects in multifragmentation were addressed
quite intensively, with particular attention being given to their relation to
the symmetry energy and its dependence on density.


title:
Excitation function of elliptic flow in Au+Au collisions and the nuclear
  matter equation of state

abstract:
  We present measurements of the excitation function of elliptic flow at
midrapidity in Au+Au collisions at beam energies from 0.09 to 1.49 GeV per
nucleon. For the integral flow, we discuss the interplay between collective
expansion and spectator shadowing for three centrality classes. A complete
excitation function of transverse momentum dependence of elliptic flow is
presented for the first time in this energy range, revealing a rapid change
with incident energy below 0.4 AGeV, followed by an almost perfect scaling at
the higher energies. The equation of state of compressed nuclear matter is
addressed through comparisons to microscopic transport model calculations.


title:
Eta photoproduction on the neutron at GRAAL: Measurement of the
  differential cross section

abstract:
  In this contribution, we will present our first preliminary measurement of
the differential cross section for the reaction gamma+n->eta+n. Comparison of
the reactions gamma+p->eta+p for free and bound proton (D2 target) will also be
discussed.


title: Beta-decay properties of $^{25}$Si and $^{26}$P

abstract:
  The $\beta$-decay properties of the neutron-deficient nuclei $^{25}$Si and
$^{26}$P have been investigated at the GANIL/LISE3 facility by means of
charged-particle and $\gamma$-ray spectroscopy. The decay schemes obtained and
the Gamow-Teller strength distributions are compared to shell-model
calculations based on the USD interaction. B(GT) values derived from the
absolute measurement of the $\beta$-decay branching ratios give rise to a
quenching factor of the Gamow-Teller strength of 0.6. A precise half-life of
43.7 (6) ms was determined for $^{26}$P, the $\beta$- (2)p decay mode of which
is described.


title: Heavy Ion Physics and Quark-Gluon Plasma

abstract:
  These proceedings represent a brief overview of the exciting physics coming
out from the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National
Laboratory. The experimental results from BRAHMS, PHOBOS, PHENIX and STAR
indicate a strongly-coupled state of matter that can only be described on the
partonic level. Here we review some of the latest experimental results as
presented at the meeting of the Division of Particles and Fields of the
American Physical Society in Riverside, CA in August 2004.


title: Gamma-Ray Spectroscopy in Lambda Hypernuclei

abstract:
  The present status of hypernuclear gamma-ray spectroscopy with Hyperball is
summarized. We observed two gamma transitions of 16-Lambda-O(1- -> 1-,0-) and
obtained the strength of the Lambda-N tensor force. In 10B(K-,pi- gamma) data,
we did not observe the spin-flip M1 transition of 10-Lambda-B(2- -> 1-), but
gamma rays from hyperfragments such as 7-Lambda-Li(7/2+ -> 5/2+) and
9-Lambda-Be(3/2+ ->1/2+) were observed. In 11B(pi+,K+ gamma) data, we observed
six gamma transitions of 11_Lambda-B. We also attempted an inclusive gamma-ray
measurement with stopped K- beam.


title: Precision measurement of the half-life and the decay branches of 62Ga

abstract:
  In an experiment performed at the Accelerator Laboratory of the University of
Jyvaskyla, the beta-decay half-life of 62Ga has been studied with high
precision using the IGISOL technique. A half-life of T1/2 = 116.09(17)ms was
measured. Using beta-gamma coincidences, the gamma intensity of the 954keV
transition and an upper limit of the beta-decay feeding of the 0+_2 state have
been extracted. The present experimental results are compared to previous
measurements and their impact on our understanding of the weak interaction is
discussed.


title: Highlights of Crystal Ball Physics

abstract:
  Differential and total cross sections are presented for pi- - and K- -induced
reactions on a proton target leading to all-neutral final states. Also shown
are rates for rare and upper limits for forbidden eta-meson decays to test
Chiral Perturbation Theory, the pi0-pi0 interactions and C and CP invariance.


title: 29Na: Defining the edge of the Island of Inversion for Z=11

abstract:
  The low-energy level structure of the exotic Na isotopes 28,29Na has been
investigated through beta-delayed gamma spectroscopy. The N=20 isotones for
Z=10-12 are considered to belong to the ``island of inversion'' where intruder
configurations dominate the ground state wave function. However, it is an open
question as to where and how the transition from normal to intruder-dominated
configurations happens in an isotopic chain. The present work, which presents
the first detailed spectroscopy of 28,29Na, clearly demonstrates that such a
transition in the Na isotopes occurs between 28Na (N=17) and 29Na (N=18),
supporting the smaller N=20 shell gap in neutron rich sd shell nuclei. The
evidence for inverted shell structure is found in intruder dominated
spectroscopy of low-lying states, beta-decay branching ratios and shell model
analysis.


title:
Study of the ground and excited states of Lambda and Sigma hyperon
  production at COSY

abstract:
  COSY with a maximum beam momentum of ~3.65 GeV/c allows the production of
ground state (Lambda and Sigma) and excited hyperons (Lambda(1405), Sigma(1385)
and Lambda(1520)) in elementary NN interactions. The existing data base in this
field is rather poor. A systematic study of the hyperon production at COSY will
result in an improvement of our understanding concerning topics like
hyperon-nucleon interaction, kaon-nucleon interaction, nucleon resonances,
strangeness production mechanism and structure of the Lambda(1405). Precise
data on Lambda and Sigma production have been produced at the COSY-11 and TOF
installation. With the WASA detector at COSY these studies can be continued and
extended to channels including photons in the final state.


title: Photoproduction of mesons from nuclei - In-medium properties of hadrons

abstract:
  Recent experimental results for the in-medium properties of hadrons obtained
with photoproduction of mesons from nuclei are discussed. The experiments were
done with the TAPS detector at the tagged photon beam of the MAMI accelerator
in Mainz. Measured were the final states $\pi^o X$, $\eta X$, $2\pi^oX$, and
$\pi^o\pi^{\pm}X$ for $^{12}$C, $^{40}$Ca, $^{93}$Nb, and $^{208}$Pb up to the
second resonance region. The results were used for an investigation of the
in-medium properties of the P$_{33}$(1232), the P$_{11}$(1440), the
D$_{13}$(1520), and the S$_{11}$(1535) resonances. It was found that the cross
sections can be spilt into a component which originates from the low density
surface region of the nuclei and a component which scales like the nuclear
volume. The energy dependence of the surface component is strikingly similar to
the deuteron, it shows a clear signal for the second resonance peak. The volume
component is lacking this peak and shows an enhancement at intermediate
energies. Furthermore the measurement of coherent $\eta$-photoproduction and
the final state $p\pi^o$ from $^3$He is discussed in the context of the search
for $\eta$-mesic nuclei.


title:
Probing bulk properties and partonic collectivity via multi-strange
  baryons in Au+Au collisions at top RHIC energy

abstract:
  The study of the multi-strange production in the final state of
ultra-relativistic Au+Au collisions at top RHIC energy gives information on the
freeze-out conditions and probably on earlier stages of the collision. The
chemical freeze-out temperature as well as the strangeness phase space
occupancy factor gamma_s extracted from statistical models are studied as a
function of the collision centrality. Within the framework of a
hydrodynamically-inspired model the transverse collectivity of the collision is
investigated. In this view, multi-strange particles seem to develop significant
radial transverse flow. Furthermore, they present an elliptic flow as stronger
as previously measured baryons supporting the idea that a fraction of the final
collective motion has been developed at an early partonic stage of the
collision.


title:
Pion, Kaon, and (Anti-) Proton Production in Au+Au Collisions at \srt =
  62.4 GeV

abstract:
  We report on preliminary results of pion, kaon, and (anti-) proton transverse
momentum spectra (-0.5 < y < 0) in Au+Au collisions at $\sqrt{s_{_{NN}}}=62.4$
GeV using the STAR detector at RHIC. The particle identification (PID) is
achieved by a combination of the STAR TPC and the new TOF detectors, which
allow a PID coverage in transverse momentum ($p_T$) up to 7 GeV/c for pions, 3
GeV/c for kaons, and 5 GeV/c for (anti-) protons.


title:
Pion interferometry in Au+Au collisions at
  $\sqrt{\mathrm{s}_{_{\mathrm{NN}}}}$ = 200 GeV

abstract:
  We present a systematic analysis of two-pion interferometry in Au+Au
collisions at $\sqrt{s_{NN}}$ = 200 GeV using the STAR detector at RHIC. We
extract the HBT radii and study their multiplicity, transverse momentum, and
azimuthal angle dependence. The Gaussianess of the correlation function is
studied. Estimates of the geometrical and dynamical structure of the freeze-out
source are extracted by fits with blast wave parameterizations. The expansion
of the source and its relation with the initial energy density distribution is
studied.


title: Production and Flow of Identified Hadrons at RHIC

abstract:
  We review the production and flow of identified hadrons at RHIC with a main
emphasis on the intermediate transverse momentum region ($2< p_{T} <5$
GeV/$c$). The goal is to unravel the dynamics of baryon production and resolve
the anomalously large baryon yields and elliptic flow observed in the
experiments.


title:
Proposal for the Wide Angle Shower Apparatus (WASA) at COSY-Juelich -
  "WASA at COSY"

abstract:
  This document describes the physics case, the key experiments proposed and
the technical solution for the project "WASA at COSY", which concerns the
transfer of the WASA pellet-target and detection system from CELSIUS (TSL,
Uppsala, Sweden) to COSY (FZJ, Juelich, Germany).


title: Review of Results from the NA49 Collaboration

abstract:
  New results of the NA49 collaboration on strange particle production are
presented. Rapidity and transverse mass spectra as well as total multiplicities
are discussed. The study of their evolution from AGS over SPS to the highest
RHIC energy reveals a couple of interesting features. These include a sudden
change in the energy dependence of the mt-spectra and of the yields of strange
hadrons around 30 AGeV. Both are found to be difficult to be reproduced in a
hadronic scenario, but might be an indication for a phase transition to a quark
gluon plasma.


title:
Saturation of azimuthal anisotropy in Au + Au collisions at sqrt(s_NN) =
  62 - 200 GeV

abstract:
  New measurements are presented for charged hadron azimuthal correlations at
mid-rapidity in Au+Au collisions at sqrt(s_NN) = 62.4 and 200 GeV. They are
compared to earlier measurements obtained at sqrt(s_NN) = 130 GeV and in Pb+Pb
collisions at sqrt(s_NN) = 17.2 GeV. Sizeable anisotropies are observed with
centrality and transverse momentum (p_T) dependence characteristic of elliptic
flow (v_2). For a broad range of centralities, the observed magnitudes and
trends of the differential anisotropy, v_2(p_T), change very little over the
collision energy range sqrt(s_NN) = 62-200 GeV, indicating saturation of the
excitation function for v_2 at these energies. Such a saturation may be
indicative of the dominance of a very soft equation of state for sqrt(s_NN) =
62-200 GeV.


title:
Measurement of the Neutron Lifetime by Counting Trapped Protons in a
  Cold Neutron Beam

abstract:
  A measurement of the neutron lifetime $\tau_{n}$ performed by the absolute
counting of in-beam neutrons and their decay protons has been completed.
Protons confined in a quasi-Penning trap were accelerated onto a silicon
detector held at a high potential and counted with nearly unit efficiency. The
neutrons were counted by a device with an efficiency inversely proportional to
neutron velocity, which cancels the dwell time of the neutron beam in the trap.
The result is $\tau_{n} = (886.6\pm1.2{\rm [stat]}\pm3.2{\rm [sys]})$ s, which
is the most precise measurement of the lifetime using an in-beam method. The
systematic uncertainty is dominated by neutron counting, in particular the mass
of the deposit and the $^{6}$Li({\it{n,t}}) cross section. The measurement
technique and apparatus, data analysis, and investigation of systematic
uncertainties are discussed in detail.


title: Determination of the low Q2 evolution of the Bjorken integral

abstract:
  We report on an experimental determination of the Q2-dependence of the
Bjorken sum using data from Jefferson Lab Hall A and Hall B in the range 0.16 <
Q2 < 1.1 GeV2. A twist analysis is performed. Overall, the higher twist
corrections are found to be small due to a cancellation between the twist 4 and
6 terms.


title: Physics at COSY

abstract:
  The COSY accelerator in J\'ulich is presented together with its internal and
external detectors. The physics programme performed recently is discussed with
emphasis on strangeness physics.


title:
Further Evidence of Narrow Baryonic Structures with Hadronic as Well as
  Leptonic Probes

abstract:
  Although extracted from several experiments using hadronic probes
\cite{bor1}, narrow baryonic structures have been sometimes met with disbelief.
New signatures are presented, which appear from already published data,
obtained with hadronic probes as well as with leptonic probes. The authors of
these results did not take into account the possibility to associate the
discontinuities of their spectra with the topic of narrow baryonic low mass
structures. The stability of the observed narrow structure masses, represents a
confirmation of their genuine existence.


title: Review of the results of the KaoS Collaboration

abstract:
  The production of K+ and of K- mesons in heavy-ion collisions at beam
energies of 1 to 2 AGeV has systematically been investigated with the Kaon
Spectrometer KaoS. The ratio of the K+ production excitation function for Au+Au
and for C+C reactions increases with decreasing beam energy, which is expected
for a soft nuclear equation-of-state. A comprehensive study of the K+ and of
the K- emission as a function of the size of the collision system, of the
collision centrality, of the kaon energy, and of the polar emission angle has
been performed. The K-/K+ ratio is found to be nearly constant as a function of
the collision centrality and can be explained by the dominance of strangeness
exchange. On the other hand the spectral slopes and the polar emission patterns
are different for K- and for K+. Furthermore the azimuthal distribution of the
particle emission has been investigated. K+ mesons and pions are emitted
preferentially perpendicular to the reaction plane as well in Au+Au as in Ni+Ni
collisions. In contrast for K- mesons in Ni+Ni reactions an in-plane flow was
observed for the first time at these incident enegies.


title: Track detector DEVIS for the double beta decay investigation

abstract:
  Detector DEVIS is TPC in the magnetic field. It is dedicated to the
investigation of the double-beta decay of Xe. Setup sensitivity was estimated
in the series of measurements with Xe with natural isotopes composition.
Detector allows measuring two-neutrino double-beta decay of $^{136}$Xe with
half-life less than $3 \cdot 10^{20}$ years.


title: Induced Quantum Entanglement of Nuclear Metastable States of 115In

abstract:
  Experiments conducted in our laboratory conclusively demonstrated that at
least 20% of 115In metastable states become quantum entangled (QE) during gamma
photo-excitation processes where a significant fraction of the photo-excitation
gamma (E > 1.02 MeV) are QE. In addition, it was found that the half-life of
115mIn populations in identical photo-excited indium foils varied as much as
70% depending on whether the 99.999% purity indium foils were photo-excited
with a High Intensity 60Co Source (HICS) or a Varian CLINAC (Compact Linear
Accelerator) with average energy 2 MeV and maximum energy 6 MeV Bremsstrahlung
photo-excitation quanta. Decay kinetics of 115mIn populations in indium foils
demonstrate that these metastable states are primarily QE in pairs when
photo-excited in the HICS apparatus and at higher orders of entanglement of
triplets and possibly quadruplets when photo-excited with the CLINAC. It
appears that QE gamma photons can transfer quantum entangled properties to
radioactive metastable states.


title: Compton Scattering by the Nucleon

abstract:
  The status of Compton scattering by the nucleon at energies of the first and
second resonance is summarized. In addition to a general test of dispersion
theories and a precise determination of polarizabilities, the validities of
four fundamental sum rules are explored. {\it Recommended} averages of
experimental values for the electromagnetic polarizabilities and
spin-polarizabilities of the nucleon are determined: $\alpha_p=12.0\pm 0.6$,
$\beta_p=1.9\mp 0.6$, $\alpha_n= 12.5 \pm 1.7$, $\beta_n= 2.7 \mp 1.8$ (unit
$10^{-4}$fm$^3$), $\gamma^{(p)}_\pi= -38.7 \pm 1.8$, $\gamma^{(n)}_\pi = 58.6
\pm 4.0$ (unit $10^{-4}$fm$^4$).


title:
Relevance of baseline hard proton-proton spectra for high-energy
  nucleus-nucleus physics

abstract:
  We discuss three different cases of hard inclusive spectra in proton-proton
collisions: high $p_T$ single hadron production at $\sqrt{s}\approx$ 20 GeV and
at $\sqrt{s}$ = 62.4 GeV, and direct photon production at $\sqrt{s}$ = 200 GeV;
with regard to their relevance for the search of Quark Gluon Plasma signals in
A+A collisions at SPS and RHIC energies.


title:
Remote Stimulated Triggering of Quantum Entangled Nuclear Metastable
  States of 115mIn

abstract:
  We report experiments in which two indium foils were quantum entangled via
photoexcitation of stable 115In to radioactive 115mIn by utilizing
Bremsstrahlung gamma photons produced by a Varian Compact Linear Accelerator
(CLINAC). After photo-excitation, remote triggering of the "master" foil with
low energy gamma photons, yielded stimulated emissions of 336 keV gamma photons
from quantum entangled 115mIn in the "slave" foil located up to 1600 m away
from the "master" foil. These experiments strongly demonstrate that useful
quantum information can be transferred through quantum channels via modulation
of quantum noise (accelerated radioactive decay of 115mIn metastable nuclei).
Thus, this modality of QE transmission is fundamentally different from optical
QE information transfer via quantum entangled space "q-bits" as developed by
information theorists for quantum channel information transfer. Additionally,
there is no obvious potential for signal degradation with increasing distance
nor the problems associated with misalignment of optical information transfer
systems.


title: Radiative strength functions in 93-98Mo

abstract:
  Radiative strength functions (RSFs) in 93-98Mo have been extracted using the
(3He,alpha gamma) and (3He,3He' gamma) reactions. The RSFs are U-shaped as
function of gamma energy with a minimum at around E_gamma=3 MeV. The minimum
values increase with neutron number due to the increase in the low-energy tail
of the giant electric dipole resonance with nuclear deformation. The unexpected
strong increase in strength below E_gamma=3 MeV, here called soft pole, is
established for all 93-98Mo isotopes. The soft pole is present at all initial
excitation energies in the 5-8 MeV region.


title: The First 3 Years at RHIC- an Overview

abstract:
  This is an overview of the results from the first 3 years of RHIC
experiments. RHIC is a collider built to accelerate nuclei to center of mass
energies of 200 GeV per nucleon for the study of QCD in bulk systems. The most
important result so far is the observation of the suppression of high p$_T$
hadrons in central Au-Au collisions followed by the subsequent null experiment
where the same suppression was not seen in deuteron-Au collisions. The observed
suppression is a final state effect in which a large amount of energy is lost
by the fast parton as it penetrates the medium. This observation, together with
measurements of the elliptic flow, leads to the conclusion that the energy
density reached is at least 10 times that of a normal nucleon. The simplest and
most economical explanation of these phenomenon is that the system is a dense,
locally thermalized system of unscreened color charges.


title: Relativistic Nuclear Collisions and the QCD Phase Boundary

abstract:
  In nucleus-nucleus collisions at ultra-relativistic energies matter is formed
with initial energy density significantly exceeding the critical energy density
for the transition from hadronic to partonic matter. We will review the
experimental evidence for this new form of matter - the Quark-Gluon Plasma -
from recent experiments at the SPS and RHIC with emphasis on collective
behavior, thermalization, and its opacity for fast partons. We will further
show that one can determine from the data a fundamental QCD parameter, the
critical temperature for the QCD phase transition.


title:
Nuclear Modification Factors for Hadrons At Forward and Backward
  Rapidities in Deuteron-Gold Collisions at sqrt(s_NN) = 200 GeV

abstract:
  We report on charged hadron production in deuteron-gold reactions at
sqrt(s_NN) = 200 GeV. Our measurements in the deuteron-direction cover 1.4 <
eta < 2.2, referred to as forward rapidity, and in the gold-direction -2.0 <
eta < -1.4, referred to as backward rapidity, and a transverse momentum range
p_T = 0.5-4.0 GeV/c. We compare the relative yields for different deuteron-gold
collision centrality classes. We observe a suppression relative to binary
collision scaling at forward rapidity, sensitive to low momentum fraction (x)
partons in the gold nucleus, and an enhancement at backward rapidity, sensitive
to high momentum fraction partons in the gold nucleus.


title: Unified Analysis of Spin Isospin Responses of Nuclei

abstract:
  We investigated the Gamow-Teller (GT) strength distribution, especially the
quenching with respect to the GT sum rule, and the enhancement of the pionic
responses in the quasielasic scattering region, in the same theoretical
framework. That is the continuum random phase approximation with the pi+rho+g'
model interaction, incorporated with distorted wave impulse approximation and
two-step calculations. From this analysis we searched the Landau-Migdal
parameters, g'NN and g'ND, through the comparison with the experimental data of
the GT strength distribution obtained at 300 MeV and the spin-longitudinal
(pionic) cross sections IDq of (p,n) at 350 and 500 MeV. This comprehensive and
sophisticated study gave a common set of g'NN=0.6-0.7 and g'ND=0.2-0.4, for
both low and high momentum transfers.


title: Measurement of the Q2-evolution of the Bjorken integral at low Q2

abstract:
  We report on the extraction of the Q2-dependence of the Bjorken sum between
0.16 < Q2 < 1.1 GeV2. A twist analysis performed on these data shows that the
higher twist corrections are small due to a cancellation between the twist-4
and 6 terms. The extraction of an effective strong coupling constant is
discussed.


title: Scaling of anisotropic flow in the picture of quark coalescence

abstract:
  Measurements of anisotropic flow at low (p_T < 1.5 GeV/c) and intermediate
(1.5 < p_T < 5 GeV/c) transverse momentum from the STAR collaboration are
reviewed. While at low p_T an ordering of elliptic flow strength with particle
mass is observed, the measured signals appear to follow number-of-constituent
quark scaling at intermediate p_T. The observations of higher harmonics support
this picture qualitatively, and are sensitive to specific model assumptions.


title:
Detailed comparison of the pp -> \pi^+pn and pp -> \pi^+d reactions at
  951 MeV

abstract:
  The positively charged pions produced in proton-proton collisions at a beam
momentum of 1640 MeV/c were measured in the forward direction with a high
resolution magnetic spectrograph. The missing mass distribution shows the bound
state (deuteron) clearly separated from the $pn$ continuum. Despite the very
good resolution, there is no evidence for any significant production of the
$pn$ system in the spin-singlet state. However, the $\sigma(pp\to
\pi^+pn)/\sigma(pp\to \pi^+d)$ cross section ratio is about twice as large as
that predicted from $S$-wave final-state-interaction theory and it is suggested
that this is due to $D$-state effects in the $pn$ system.


title:
Observation of modified hadronization in relativistic Au+Au collisions:
  a promising signature for deconfined quark-gluon matter

abstract:
  Measurements of identified particles from Au+Au collisions at
$\sqrt{s_{_{NN}}}=200$ GeV are reviewed. Emphasis is placed on nuclear
modification, baryon-to-meson ratios, and elliptic flow at intermediate
transverse momentum ($1.5 < p_T < 5$ GeV/c). Possible connections between (1)
these measurements, (2) the running coupling for static quark anti-quark pairs
at finite temperature, and (3) the creation of a deconfined quark-gluon phase
are presented. Modifications to hadronization in Au+Au collisions are proposed
as a likely signature for the creation of deconfined colored matter.


title:
From Bjorken Scaling to pQCD--Experimental techniques from p-p
  collisions of the 1970's with application to Au+Au collisions at RHIC

abstract:
  Hard scattering in p-p collisions was discovered at the CERN ISR in 1972, by
the method of leading particles, which proved that the partons of Deeply
Inelastic Scattering strongly interacted with each other. Further ISR
measurements utilizing inclusive single or pairs of hadrons established that
high pT particles are produced from states with two roughly back-to-back jets
which are the result of scattering of constituents of the nucleons as described
by Quantum Chromodynamics. These techniques, which are the only practical
method to study hard-scattering and jet phenomena in Au+Au collisions at RHIC,
will be reviewed.


title: Evidence for Neutrino Oscillations I: Solar and Reactor Neutrinos

abstract:
  This paper discusses evidence for neutrino oscillations obtained from
measurements with solar neutrinos and reactor neutrinos.


title: In-medium properties of nucleon resonances

abstract:
  Recent experimental results for the in-medium properties of nucleon
resonances are discussed. The experiments were done with the TAPS detector at
the tagged photon beam of the MAMI accelerator in Mainz. Measured was the
photoproduction of mesons (final states $\pi^o X$, $\eta X$, $2\pi^oX$ and
$\pi^o\pi^{\pm}X$) from the nuclei $^{12}$C, $^{40}$Ca, $^{93}$Nb, and
$^{208}$Pb up to the second resonance region. The results were analyzed in view
of the in-medium properties of the P$_{33}$(1232), the D$_{13}$(1520), and the
S$_{11}$(1535) resonances.


title:
Correlations between signals of the liquid-gas phase transition in
  nuclei

abstract:
  Finite systems such as atomic nuclei present at phase transition specific
features different from those observed at the thermodynamic limit. Several
characteristic signals were found in samples of events resulting from heavy ion
collisions at and above the Fermi energy. The concomitant observation of
different signatures of a liquid-gas phase transition in nuclei on a given
sample strongly supports the occurrence of this transition.


title: Thoughts on Heavy Quark Production

abstract:
  Various aspects of heavy flavor production in heavy ion collisions in the
context of elementary collisions are reviewed. The interplay between theory in
experiment in $\epem$ and $\pbarp$ data is been found to be non-trivial, even
with new NLO calculations. Quarkonium suppression in p+A and A+A show puzzling
features, apparently connected to features of inclusive particle production.
Open charm is found to scale as expected for a hard process, but strangeness is
also found to share these features. These features contribute to heavy flavor
as a interesting probe of strong interactions.


title: Bulk Dynamics in Heavy Ion Collisions

abstract:
  The features of heavy ion collisions that suggest the relevance of collective
dynamics, as opposed to mere superpositions of nucleon-nucleon or even
parton-parton collisions, are reviewed. The surprise of these studies is that
bulk observables are far simpler than typical dynamical models of
nucleus-nucleus collisions would imply. These features are shown to have a
natural interpretation in terms of statistical-hydrodynamical models. The
relevance of hydrodynamics to heavy ion collisions, coupled with the various
similarities of the heavy ion data with that of more elementary collisions,
raises very basic questions about its relevance to smaller systems.


title:
The Chemical Separation of Eka-Hg from CERN W Targets in view of Recent
  Relativistic Calculations

abstract:
  In 1971 evidence for the production of element 112 via secondary reactions in
CERN W targets was obtained. The evidence was mainly based on the observation
of fission fragments in Hg sources separated from the W targets, on the
measured masses of the fissioning nuclei and on the assumption that element 112
(Eka-Hg) actually behaves like Hg in the chemical separation process. This
assumption is analyzed in view of recent relativistic calculations of the
electronic structure of element 112. It is shown that in the superheavy element
region only the chemistry of element 112 is similar to that of Hg.


title: Strangelet search at RHIC

abstract:
  Two position sensitive Shower Maximum Detector (SMDs) for Zero-Degree
Calorimeters (ZDCs) were installed by STAR before run 2004 at both upstream and
downstream from the interaction point along the beam axis where particles with
small rigidity are swept away by strong magnetic field. The ZDC-SMDs provides
information about neutral energy deposition as a function of transverse
position in ZDCs. We report the preliminary results of strangelet search from a
triggered data-set sampling 100 million Au+Au collisions at top RHIC energy.


title: Spin Physics with STAR at RHIC

abstract:
  STAR collected data in proton-proton collisions at sqrt(s)=200 GeV with
transverse and longitudinal beam polarizations during the initial running
periods in 2002--2004 at the Relativistic Heavy Ion Collider at Brookhaven
National Laboratory. Results on the single transverse spin asymmetries in the
production of high energy forward neutral pions and of forward charged hadrons
will be presented. Data have been obtained for double longitudinal asymmetries
in inclusive jet production in 2003 and 2004. These data provide sensitivity to
the polarization of gluons in the proton. In the future, we aim to determine
the gluon polarization over a wide kinematic range using coincidences of direct
photons and jets. Furthermore, we aim to determine the polarizations of the u,
bar(u), d and bar(d) quarks in the proton by measuring single longitudinal spin
asymmetries in the production of weak bosons at sqrt(s) = 500$ GeV.


title: Energy dependence of strangeness production

abstract:
  We present a summary of strange particle yields measured by the experiment
NA49 in central Pb+Pb collisions in the beam energy range 20-158 AGeV. The
comparison with thermal hadron model results shows that above 30 AGeV, a
strangeness undersaturation parameter gamma_S must be employed to describe the
data. This suggests a change in the strangeness production mechanism at this
energy. We find that the UrQMD transport model in all cases underpredicts the
observed particle yields.


title:
Excitation functions of spin correlation parameters A_{NN}, A_{SS}, and
  A_{SL} in elastic pp scattering between 0.45 and 2.5 GeV

abstract:
  Excitation functions of the spin correlation coefficients
A_{NN}(p_{lab},theta_{c.m.}), A_{SS}(p_{lab},theta_{c.m.}), and
A_{SL}(p_{lab},theta_{c.m.}) have been measured with the polarized proton beam
of the Cooler Synchrotron COSY and an internal polarized atomic beam target.
Data were taken continuously during the acceleration for proton momenta p_{lab}
ranging from 1000 to 3300 MeV/c (kinetic energies T_{lab} 450 - 2500 MeV) as
well as for discrete momenta of 1430 MeV/c and above 2000 MeV/c covering angles
theta_{c.m.} between 30 deg and 90 deg. The data are of high internal
consistency. Whereas A_{SL}(p_{lab,}theta_{c.m.}) is small and without
structures in the whole range, A_{NN} and even more A_{SS} show a pronounced
energy dependence. The angular distributions for A_{SS} are at variance with
predictions of existing phase shift analyses at energies beyond 800 MeV. The
impact of our results on phase shift solutions is discussed. The direct
reconstruction of the scattering amplitudes from all available pp elastic
scattering data considerably reduces the ambiguities of solutions.


title: Volume Effects on Strangeness Production

abstract:
  A study of the yields of strange particles produced in heavy-ion and
elementary collisions is presented using preliminary results from the STAR
experiment at RHIC. The strange particle production rates, relative to those of
p+p, have been proposed as a means of determining an enhancement of strangeness
production in heavy-ion collisions. Analysis of results from STAR show that
this enhancement measure is reduced, or comparable, when contrasted to that at
top CERN SPS energies. A smaller suppression in the p+p yields at RHIC energies
due to finite volume effects could be the cause of such a result. By studying
the yields as a function of centrality we hope to establish how these effects
vary with the volume of the source created.


title:
What's Interesting About Strangeness Production? - An Overview of Recent
  Results

abstract:
  In this paper I highlight a few selected topics on strange particle
production in heavy-ion collisions. By studying the yield and spectra of
strange particles we hope to gain understanding of the conditions reached in,
and the ensuing dynamics of, the systems produced when ultra-relativistic
heavy-ions are collided.


title:
Comments on the question of the discovery of element 112 as early as
  1971

abstract:
  There are two independent claims for the discovery of element 112: The claim
by Hofmann et al. from 1996 and the older claim from 1971 by Marinov et al.
This Comment will not challenge the experimental results of Hofmann et al., but
it will discuss one aspect of the claimed discovery of element 112 by Marinov
et al., as their experiment has never been reproduced in exactly the form in
which the original experiment has been carried out. The reasons for this
deficiency may not be found in the field of science, but possibly in
radioprotection restrictions for researchers who want to carry out such an
experiment. However, such is not a sufficient reason to exclude the original
claim from all considerations of the responsible international authorities, who
have to settle such priority questions. It may be in agreement with scientific
traditions, that when the responsible international committees do not feel to
be able to come to a positive decision on the "1971" claim, they could keep the
priority problem unsettled for the time being.


title: Indications for the onset of deconfinement in nucleus nucleus collisions

abstract:
  The hadronic final state of central Pb+Pb collisions at 20, 30, 40, 80, and
158 AGeV has been measured by the CERN NA49 collaboration. The mean transverse
mass of pions and kaons at midrapidity stays nearly constant in this energy
range, whereas at lower energies, at the AGS, a steep increase with beam energy
was measured. Compared to p+p collisions as well as to model calculations,
anomalies in the energy dependence of pion and kaon production at lower SPS
energies are observed. These findings can be explained, assuming that the
energy density reached in central A+A collisions at lower SPS energies is
sufficient to force the hot and dense nuclear matter into a deconfined phase.


title:
K(892)* Resonance Production in Au+Au and p+p Collisions at sqrt(sNN) =
  200 GeV at RHIC

abstract:
  The short-lived $K(892)^{*}$ resonance provides an efficient tool to probe
properties of the hot and dense medium produced in relativistic heavy-ion
collisions. We report measurements of $K^{*}$ in $\sqrt{s_{_{NN}}}$ = 200 GeV
Au+Au and $p+p$ collisions reconstructed via its hadronic decay channels
$K(892)^{*0} \to K\pi$ and $K(892)^{*\pm} \to K_S^0\pi^{\pm}$ using the STAR
detector at RHIC. The $K^{*0}$ mass has been studied as a function of $p_T$ in
minimum bias $p+p$ and central Au+Au collisions. The $K^{*}$ $p_T$ spectra for
minimum bias $p+p$ interactions and for Au+Au collisions in different
centralities are presented. The $K^{*}/K$ yield ratios for all centralities in
Au+Au collisions are found to be significantly lower than the ratio in minimum
bias $p+p$ collisions, indicating the importance of hadronic interactions
between chemical and kinetic freeze-outs. A significant non-zero $K^{*0}$
elliptic flow ($v_2$) is observed in Au+Au collisions and compared to the
$K_S^0$ and $\Lambda$ $v_2$. The nuclear modification factor of $K^{*}$ at
intermediate $p_{T}$ is similar to that of $K_{S}^{0}$, but different from
$\Lambda$. This establishes a baryon-meson effect over a mass effect in the
particle production at intermediate $p_T$ ($2 < p_T \leq 4$ GeV/$c$).


title:
Tensor Ayy and Vector Ay Analyzing Powers of the (d,p) and (d,d)
  Reactions at 5 Gev/c and 178 MR

abstract:
  New data on the tensor analyzing power Ayy of the ^9Be(d,p)X reaction at an
initial deuteron momentum of 5 GeV/c and secondary particles (protons and
deuterons) detection angle of 178 mr have been obtained at the JINR
Synchrophasotron.
  The proton data obtained are analyzed within the framework of an approach
based on the light-front dynamics using Karmanov's relativistic deuteron wave
function. Contrary to the calculations with standard non-relativistic deuteron
wave functions, we have managed to explain the new data within the framework of
our approach without invoking degrees of freedom additional to nucleon ones.
  The ^9Be(d,d)X data are obtained in the vicinity of the excitation of
baryonic resonances with masses up to 1.8 GeV/c^2. The Ayy data are in a good
agreement with the previous data obtained at 4.5 and 5.5 GeV/c when they are
plotted versus $t$. The results of the experiment are compared with the
predictions of the plane wave impulse approximation and \omega-meson exchange
models.


title:
Application of PbWO4 crystal scintillators in experiment to search for
  double beta decay of 116Cd

abstract:
  PbWO4 crystal scintillators are discussed as an active shield and
light-guides in 116Cd double beta decay experiment with CdWO4 scintillators.
Scintillation properties and radioactive contamination of PbWO4 scintillators
were investigated. Energy resolution of CdWO4 detector, coupled to PbWO4
crystal as a light-guide, was tested. Efficiency of PbWO4-based active shield
to suppress background from the internal contamination of PbWO4 crystals was
calculated. Using of lead tungstate crystal scintillators as high efficiency
4-pi active shield could allow to build sensitive double beta experiment with
116CdWO4 crystal scintillators.


title:
Multi-strange baryon correlations in p+p and d+Au collisions at
  $\sqrt{s}=200$ GeV

abstract:
  Multi-strange baryon correlations with charged hadrons have been measured in
the p+p and d+Au reference systems at s^(0.5) = 200 GeV per nucleon pair, for
future comparison with correlations in Au+Au collisions. Weak correlation peaks
are observed on both the same side as the high pT (pT > 2 GeV/c) Xi (the
trigger particle), and on the away side (pi radians away in azimuth) in the p+p
data. A quantitative analysis requires better statistics than is presently
available. Distinct peaks are also seen in PYTHIA simulations of p+p
collisions, but spectra comparison between PYTHIA and data shows that PYTHIA
does not reproduce the data. A clear correlation is also present in d+Au data,
establishing a reference foundation for a future Au+Au study.


title:
Overview of Hard processes at RHIC: high-pt light hadron and charm
  production

abstract:
  An overview of the experimental results on high-pt light hadron production
and open charm production is presented. Data on particle production in
elementary collisions are compared to next-to-leading order perturbative QCD
calculations. Particle production in Au+Au collisions is then compared to this
baseline.


title:
The reaction 2H(p,pp)n in three kinematical configurations at E_p = 16
  MeV

abstract:
  We measured the cross sections of the $^2$H(p,pp)n breakup reaction at
E$_p$=16 MeV in three kinematical configurations: the np final-state
interaction (FSI), the co-planar star (CST), and an intermediate-star (IST)
geometry. The cross sections are compared with theoretical predictions based on
the CD Bonn potential alone and combined with the updated 2$\pi$-exchange
Tucson-Melbourne three-nucleon force (TM99'), calculated without inclusion of
the Coulomb interaction. The resulting excellent agreement between data and
pure CD Bonn predictions in the FSI testifies to the smallness of three-nucleon
force (3NF) effects as well as the insignificance of the Coulomb force for this
particular configuration and energy. The CST also agrees well whereas the IST
results show small deviations between measurements and theory seen before in
the pd breakup space-star geometries which point to possible Coulomb effects.
An additional comparison with EFT predictions (without 3NF) up to order N$^3$LO
shows excellent agreement in the FSI case and a rather similar agreement as for
CD Bonn in the CST and IST situations.


title:
Quasi-free production of the eta and eta-prime mesons in nucleon-nucleon
  collisions

abstract:
  Some aspects of the quasi-free production of mesons in the near threshold
region are discussed. A method of data analysis used by WASA/PROMICE
Collaboration to extract the excitation function for eta production on neutron
target is briefly presented. Feasibility of similar study with WASA at COSY is
discussed.


title:
Measurement of the Absolute np Scattering Differential Cross Section at
  194 MeV

abstract:
  We describe a double-scattering experiment with a novel tagged neutron beam
to measure differential cross sections for np back-scattering to better than 2%
absolute precision. The measurement focuses on angles and energies where the
cross section magnitude and angle-dependence constrain the charged pion-nucleon
coupling constant, but existing data show serious discrepancies among
themselves and with energy-dependent partial wave analyses (PWA). The present
results are in good accord with the PWA, but deviate systematically from other
recent measurements.


title:
Angular Distributions for 3,4 Lambda H Bound States in the 3,4
  He(e,e'K+) reaction

abstract:
  The 3Lambda H and 4Lambda H hypernuclear bound states have been observed for
the first time in kaon electroproduction on 3,4He targets. The production cross
sections have been determined at Q**2= 0.35 GeV**2 and W= 1.91 GeV. For either
hypernucleus the nuclear form factor is determined by comparing the angular
distribution of the 3,4He(e,e'K+)3,4Lambda H processes to the elementary cross
section 1H(e,e'K+) Lambda on the free proton, measured during the same
experiment.


title:
$p$-$sd$ shell gap reduction in neutron-rich systems and cross-shell
  excitations in $^{20}$O

abstract:
  Excited states in $^{20}$O were populated in the reaction
$^{10}$Be($^{14}$C,$\alpha$) at Florida State University. Charged particles
were detected with a particle telescope consisting of 4 annularly segmented Si
surface barrier detectors and $\gamma$ radiation was detected with the FSU
$\gamma$ detector array. Five new states were observed below 6 MeV from the
$\alpha$-$\gamma$ and $\alpha$-$\gamma$-$\gamma$ coincidence data. Shell model
calculations suggest that most of the newly observed states are core-excited
1p-1h excitations across the $N = Z = 8$ shell gap. Comparisons between
experimental data and calculations for the neutron-rich O and F isotopes imply
a steady reduction of the $p$-$sd$ shell gap as neutrons are added.


title:
Level densities and $\gamma$-ray strength functions in
  $^{170,171,172}$Yb

abstract:
  Level densities and radiative strength functions in $^{171}$Yb and $^{170}$Yb
nuclei have been measured using the
$^{171}$Yb($^3$He,$^3$He$^\prime\gamma$)$^{171}$Yb and
$^{171}$Yb($^3$He,$\alpha\gamma$)$^{170}$Yb reactions. New data on $^{171}$Yb
are compared to a previous measurement for $^{171}$Yb from the
$^{172}$Yb($^3$He,$\alpha\gamma$)$^{171}$Yb reaction. Systematics of level
densities and radiative strength functions in $^{170,171,172}$Yb are
established. The entropy excess in $^{171}$Yb relative to the even-even nuclei
$^{170,172}$Yb due to the unpaired neutron quasiparticle is found to be
approximately 2$k_B$. Results for the radiative strength function from the two
reactions lead to consistent parameters characterizing the ``pygmy''
resonances. Pygmy resonances in the $^{170,172}$Yb populated by the
($^3$He,$\alpha$) reaction appear to be split into two components for both of
which a complete set of resonance parameters are obtained.


title:
Evidence for Strange Quark Contributions to the Nucleon's Form Factors
  at $Q^2$ = 0.108 (GeV/c)$^2$

abstract:
  We report on a measurement of the parity violating asymmetry in the elastic
scattering of polarized electrons off unpolarized protons with the A4 apparatus
at MAMI in Mainz at a four momentum transfer value of $Q^2$ = \Qsquare
(GeV/c)$^2$ and at a forward electron scattering angle of 30$^\circ < \theta_e
< 40^\circ$. The measured asymmetry is $A_{LR}(\vec{e}p)$ = (\Aphys $\pm$
\Deltastat$_{stat}$ $\pm$ \Deltasyst$_{syst}$) $\times$ 10$^{-6}$. The
expectation from the Standard Model assuming no strangeness contribution to the
vector current is A$_0$ = (\Azero $\pm$ \DeltaAzero) $\times$ 10$^{-6}$. We
have improved the statistical accuracy by a factor of 3 as compared to our
previous measurements at a higher $Q^2$. We have extracted the strangeness
contribution to the electromagnetic form factors from our data to be $G_E^s$ +
\FakGMs $G_M^s$ = \GEsGMs $\pm $ \DeltaGEsGMs at $Q^2$ = \Qsquare (GeV/c)$^2$.
As in our previous measurement at higher momentum transfer for $G_E^s$ + 0.230
$G_M^s$, we again find the value for $G_E^s$ + \FakGMs $G_M^s$ to be positive,
this time at an improved significance level of 2 $\sigma$.


title:
Lambda Production at Forward and Backward Rapidity in d+Au Collisions at
  sqrt(s_NN) = 200 GeV

abstract:
  Using the forward time projection chambers of the STAR experiment at the
Brookhaven Relativistic Heavy Ion Collider we measure the centrality dependent
Lambda and Anti-Lambda yields and inverse slope parameters in d+Au collisions
at forward and backward rapidities y = +- 2.75. The contributions of different
processes to stopping and baryon transport are probed exploiting the inherent
asymmetry of the d+Au system. Comparisons to model calculations show that the
baryon transport on the deuteron side is due to multiple collisions of the
deuteron nucleons with gold participants. On the gold side, the inclusion of
inital state nuclear effects or hadronic rescattering is necessary to describe
the data.


title:
Scalar interaction limits from the beta-neutrino correlation of trapped
  radioactive atoms

abstract:
  We have set limits on contributions of scalar interactions to nuclear beta
decay. A magneto-optical trap (MOT) provides a localized source of atoms
suspended in space, so the low-energy recoiling nuclei can freely escape and be
detected in coincidence with the beta. This allows reconstruction of the
neutrino momentum, and the measurement of the beta-neutrino correlation, in a
more direct fashion than previously possible. The beta-neutrino correlation
parameter of the 0+ to 0+ pure Fermi decay of 38mK is
$\tilde{a}$=0.9981+-0.0030+-0.0037, consistent with the standard model
prediction a=1.


title: Highlights of Recent Results with Clas

abstract:
  Recent results on the study of the electromagnetic structure of nucleon
resonances, the spin structure of proton and neutrons at small and intermediate
photon virtualities, and the search for exotic pentaquark baryons are
presented.


title: Reconstructing Sigma0 decays in STAR

abstract:
  Typical experimental measurements do not separate the contributions of Sigma
state decays from (anti)Lambda yields. An ongoing analysis in STAR is resolving
the contribution from excited Sigma states, but the primary contribution comes
from electromagnetic decays of the (anti)Sigma0.
  Photon conversions into e+e- pairs in detector material have been used by
STAR to identify photons from pi0 decays. A similar technique has been used
here to identify photons from (anti)Sigma0 decays in conjunction with STAR's
excellent PID capabilities for finding the associated (anti)Lambda daughters.
We report here on progress toward measuring the (anti)Sigma0 yields in various
nuclear collisions at RHIC.


title: Electroproduction of K* mesons at CLAS

abstract:
  The electroproduction of K$^{*0}$ mesons using the CLAS detector is
described. Data for two electron beam energies, 4.056 and 4.247 GeV, were
measured and the normalized yields are compared.


title:
Search for and study of eta-mesic nuclei in pA-collisions at the JINR
  LHE nuclotron

abstract:
  An approved experiment at the internal proton beam of the JINR nuclotron on a
search for eta-mesic nuclei in the reaction pA --> np + eta(A-1) --> np + pi-p
+ X is briefly presented.


title: "Safe" Coulomb Excitation of 30Mg

abstract:
  We report on the first radioactive beam experiment performed at the recently
commissioned REX-ISOLDE facility at CERN in conjunction with the highly
efficient gamma spectrometer MINIBALL. Using 30Mg ions accelerated to an energy
of 2.25 MeV/u together with a thin nat-Ni target, Coulomb excitation of the
first excited 2+ states of the projectile and target nuclei well below the
Coulomb barrier was observed. From the measured relative de-excitation gamma
ray yields the B(E2; 0+ -> 2+) value of 30Mg was determined to be 241(31)
e2fm4. Our result is lower than values obtained at projectile fragmentation
facilities using the intermediate-energy Coulomb excitation method, and
confirms the theoretical conjecture that the neutron-rich magnesium isotope
30Mg lies still outside the ``island of inversion''.


title:
Correlation functions and emission time sequence of light charged
  particles from projectile-like fragment source in E/A = 44 and 77 MeV 40Ar +
  27Al collisions

abstract:
  Two-particle correlation functions, involving protons, deuterons, tritons,
and alpha-particles, have been measured at very forward angles (0.7 deg <
theta_lab < 7 deg), in order to study projectile-like fragment (PLF) emission
in E/A = 44 and 77 MeV 40Ar + 27Al collisions. Peaks, originating from
resonance decays, are larger at E/A = 44 than at 77 MeV. This reflects the
larger relative importance of independently emitted light particles, as
compared to two-particle decay from unstable fragments, at the higher beam
energy. The time sequence of the light charged particles, emitted from the PLF,
has been deduced from particle-velocity-gated correlation functions (discarding
the contribution from resonance decays). Alpha-particles are found to have an
average emission time shorter than protons but longer than tritons and
deuterons.

Recoil spectrometers for heavy-ion identification and secondary-beam
  production: pushing the low-energy limit

abstract:
  The feasibility of low-energy fragmentation experiments using a magnetic
spectrometer is discussed. The main challenge is the multiplicity of the ionic
charge states, which can hamper the identification in both Z and A of the
fragments. Three topics are covered. First, a specific set-up for ionization
chambers, based on a very large gas thickness, is presented. Its satisfactory
performances are discussed in light of the observations during a 500A MeV Pb+p
experiment performed at the FRS (GSI). As a second topic, the possibility to
use a thick layer of matter (a degrader) as a passive measurement device to
identify the nuclear charge and the ionic charge state of fragments is
discussed. This method, successfully used for Z identification in experiments
such as Pb+p at 1A GeV, fails to measure the charge states at 500A MeV for the
same system. It is shown that surface defects of the degrader are probably
responsible for this failure. The third topic is the description of new
analysis techniques developed in order to account for and subtract the
contribution of polluting charge states in the spectrometer, thus making
possible a clean estimation of the production cross sections of all fragments.
The combination of those new experimental and analysis techniques made the 500A
MeV spallation experiment a success.
