Using Jet Asymmetries to access the Gluon Helicity Distribution of the
  Proton at STAR

abstract:
  We present the first inclusive jet longitudinal double spin asymmetry A_LL
and differential cross-section measurement from STAR. This analysis reflects ~1
pb^-1 of polarized pp data taken at sqrt{s}=200 GeV with beam polarizations of
30-45% in years 2003 and 2004. Agreement between the measured differential
cross-section and next-to-leading order (NLO) calculations validate the
interpretation of the asymmetry results within the framework of perturbative
Quantum Chromodynamics (pQCD). A_LL is compared to NLO pQCD calculations, which
incorporate several possible gluon helicity distributions, and is shown to
disfavor the maximum gluon scenario.

Neutral Pion Double Longitudinal Spin Asymmetry in Proton-Proton
  Collisions at sqrt(s)=200 GeV Using the PHENIX Detector

abstract:
  New results from polarized p-p collisions at sqrt(s)=200 GeV of double
longitudinal spin asymmetry in pi0 production using the PHENIX detector in the
2005 RHIC run are presented. Both positive and negative maximal gluon
polarization scenarios are inconsistent with the data. The data is consistent
with small |\Delta g|, including \Delta g=0.


title: Progress on Quarkonium Studies in STAR

abstract:
  We review recent progress on the study of quarkonium production with the STAR
detector. We discuss the results of a J/psi -> e+e- test trigger for p+p
collisions during Run V at RHIC. For the Au+Au data from Run IV, we discuss the
implementation of a test trigger for Upsilon -> e+e-. We obtain an upper limit
on Upsilon production from the test trigger data. The prospects for future runs
with upgraded detectors are outlined.


title: Heavy flavor physics at STAR

abstract:
  In these proceedings, heavy flavor production as measured by STAR is
disscussed. This can be done directly by reconstruction of the hadronic decays
or indirectly by the measurement of electrons from semileptonic decays of heavy
quark mesons. The extracted charm production total cross-section per
nucleon-nucleon collision in d+Au and Au+Au collisions shows binary scaling,
supporting the idea that charm quarks are produced in hard scattering in the
initial phase of the collision. The preliminary non-photonic electron spectra
from $p+p$, $d+Au$ and $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV at
mid-rapidity are presented. The momentum range of reconstructed non-photonic
electrons is $1.5 < p_{T}< 10$ GeV/c. The dominant contribution to the
non-photonic electron spectrum is the semi-leptonic decay of D and B mesons.
The electron nuclear modification factor ($R_{AA}$) shows a large suppression
in central Au+Au collisions, indicating an unexpectedly large energy loss for
heavy quarks in the hot and dense matter created at RHIC. Theoretical models
tend to overpredict the data if the contributions from both charm and beauty
decays are taken into account.


title: The Radioactive Beam Program at Argonne

abstract:
  In this talk I will present selected topics of the ongoing radioactive beam
program at Argonne and discuss the capabilities of the CARIBU radioactive ion
production facility as well as plans for construction of a novel
superconducting solenoid spectrometer.


title: Fusion-Fission of 16O+197Au at Sub-Barrier Energies

abstract:
  The recent discovery of heavy-ion fusion hindrance at far sub-barrier
energies has focused much attention on both experimental and theoretical
studies of this phenomenon. Most of the experimental evidence comes from
medium-heavy systems such as Ni+Ni to Zr+Zr, for which the compound system
decays primarily by charged-particle evaporation. In order to study heavier
systems, it is, however, necessary to measure also the fraction of the decay
that goes into fission fragments. In the present work we have, therefore,
measured the fission cross section of 16O+197Au down to unprecedented far
sub-barrier energies using a large position sensitive PPAC placed at backward
angles. The preliminary cross sections will be discussed and compared to
earlier studies at near-barrier energies. No conclusive evidence for
sub-barrier hindrance was found, probably because the measurements were not
extended to sufficiently low energies.


title:
Systematic Study of Particle Production at High p_T with the PHENIX
  Experiment

abstract:
  A systematic study of particle production at large transverse momentum with
the PHENIX experiment at RHIC is shown. We demonstrate that the suppression of
the yield of high p_T hadrons in central Au+Au collisions compared to the
scaled p+p reference persists up to highest p_T for neutral pions and eta
mesons. A similar suppression pattern is also observed in Cu+Cu collisions at
the same energy. In addition we present the first RHIC results on high-p_T
particle production close to SPS energies.


title:
Scaling Properties of Hyperon Production in Au+Au Collisions at
  sqrt(s_NN) = 200 GeV

abstract:
  We present the scaling properties of Lambda, Xi, Omega and their
anti-particles produced at mid-rapidity in Au+Au collisions at RHIC at
sqrt(s_NN) = 200 GeV. The yield of multi-strange baryons per participant
nucleon increases from peripheral to central collisions more rapidly than the
Lambda yield, which appears to correspond to an increasing strange quark
density of matter produced. The value of the strange phase space occupancy
factor gamma_s, obtained from a thermal model fit to the data, approaches unity
for the most central collisions. We also show that the nuclear modification
factors, R_CP, of Lambda and Xi are consistent with each other and with that of
protons in the transverse momentum range 2.0 < p_T < 5.0 GeV/c. This scaling
behaviour is consistent with a scenario of hadron formation from constituent
quark degrees of freedom through quark recombination or coalescence.


title: Proton G_E/G_M from beam-target asymmetry

abstract:
  The ratio of the proton's electric to magnetic form factor, G_E/G_M, can be
extracted in elastic electron-proton scattering by measuring either cross
sections, beam-target asymmetry or recoil polarization. Separate determinations
of G_E/G_M by cross sections and recoil polarization observables disagree for
Q^2 > 1 (GeV/c)^2. Measurement by a third technique might uncover an unknown
systematic error in either of the previous measurements. The beam-target
asymmetry has been measured for elastic electron-proton scattering at Q^2 =
1.51 (GeV/c)^2 for target spin orientation aligned perpendicular to the beam
momentum direction. This is the largest Q^2 at which G_E/G_M has been
determined by a beam-target asymmetry experiment. The result, \muG_E/G_M =
0.884 +/- 0.027 +/- 0.029, is compared to previous world data.


title: Vertex reconstruction algorithms in the PHOBOS experiment at RHIC

abstract:
  The PHOBOS experiment at the Relativistic Heavy Ion Collider (RHIC) at
Brookhaven National Laboratory is studying interactions of heavy nuclei at the
largest energies available in the laboratory. The high multiplicity of
particles created in heavy ion collisions makes precise vertex reconstruction
possible using information from a spectrometer and a specialized vertex
detector with relatively small acceptances. For lower multiplicity events, a
large acceptance, single layer multiplicity detector is used and special
algorithms are developed to reconstruct the vertex, resulting in high
efficiency at the expense of poorer resolution. The algorithms used in the
PHOBOS experiment and their performance are presented.


title:
Measurements of J/$\psi$ yields at forward and mid-rapidity in d+Au,
  Cu+Cu and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV by PHENIX at RHIC

abstract:
  The J/$\psi$ yields in heavy ion collisions are expected to be a promising
probe of deconfined matter, since theoretical models predict that the J/$\psi$
production could be strongly suppressed due to color screening effect in a
Quark Gluon Plasma. In addition, one of the interesting predictions that has
emerged recently is the J/$\psi$ enhancement at RHIC energy via competing
mechanisms such as recombination. The PHENIX collaboration has measured
J/$\psi$ production via its decay into lepton pairs in Au+Au and Cu+Cu
collisions at $\sqrt{s_{NN}}$ = 200 GeV. The nuclear modification factor
$R_{\rm AA}$ for the ${\rm J}/\psi$ is obtained by comparing Au+Au or Cu+Cu
collisions to p+p collisions. The $R_{\rm AA}$ dependences on centrality,
transverse momentum and rapidity are presented both at forward rapidity
($1.2<|y|<2.2$) using ${\rm J}/\psi\to\mu^+\mu^-$ and at mid rapidity
($|y|<0.35$) using ${\rm J}/\psi\to e^+e^-$. These preliminary results are
compared to cold nuclear matter expectations derived from PHENIX d+Au
measurements, to results obtained by NA50 experiment and to various theoretical
models.


title:
Long-Range Multiplicity Correlations in Au+Au at $\sqrt{s_{NN}}$ = 200
  GeV

abstract:
  We present data on long-range multiplicity correlations in ultra-relativistic
heavy ion collisions at the top RHIC energy ($\sqrt{s_{NN}}$ = 200 GeV) from
the STAR experiment. The data shows a long-range multiplicity correlation
extending across a gap of 1.6 units in pseudorapidity. The data is over
predicted by a multiparticle production model with hadronization of independent
strings, or fusion of two color strings. This can be interpreted in terms of
additional dynamical reduction in the number of particle sources.


title:
Transverse Momentum Distributions and String Percolation Study in p+p,
  d+Au and Au+Au at $\sqrt{s_{NN}}$ = 200 GeV

abstract:
  Multiparticle production at high energies is described in terms of color
strings stretched between the projectile and target. As string density
increases, overlap among the strings leads to cluster formation. At some
critical density a macroscopic cluster appears, spanning the entire system.
This marks the percolation phase transition. Data from p+p, d+Au and Au+Au
collisions at 200 GeV has been analyzed using the STAR detector to obtain the
percolation density parameter, $\eta$. For 200 GeV Au+Au collisions, the value
of $\eta$ is found to lie above the critical percolation threshold, while for
200 GeV d+Au collisions it is below the critical value. This supports the idea
of string percolation, which at high enough string density is a possible
mechanism to explore the hadronic phase transition to a quark-gluon plasma.


title: Strange Particle Production and Elliptic Flow from CERES

abstract:
  Elliptic flow measurements as a function of p_T of charged (pi^+- and low-p_T
protons) and strange (Lambda and K^0_S) particles from Pb+Au collisions at 158
AGeV/c are presented, together with measurements of phi and K^0_S meson
production. A mass ordering effect was observed. Scaling to the number of
constituent quarks and transverse rapidity y^fs_T scaling are presented. The
results are compared with results from the NA49 and STAR experiments and with
hydrodynamical calculations. For the first time in heavy-ion collisions, phi
mesons were reconstructed in the same experiment both in the K^+K^- and in the
e^+e^- decay channels. The obtained transverse mass distributions of phi mesons
are compared with results from the NA49 and NA50 experiments. The yield and the
inverse slope parameter of the K^0_S mesons were reconstructed from two
independent analyses. Our results are compared with those from the NA49 and
NA57 experiments.


title:
A study of the proton spectra following the capture of $K^-$ in $^6$Li
  and $^{12}$C with FINUDA

abstract:
  Momenta spectra of protons emitted following the capture of $K^-$ in $^6$Li
and $^{12}$C have been measured with 1% resolution. The $^{12}$C spectrum is
smooth whereas for $^6$Li a well defined peak appears at about 500 MeV/$c$. The
first observation of a structure in this region was identified as a strange
tribaryon or, possibly, a $\bar K$-nuclear state. The peak is correlated with a
$\pi^-$ coming from $\Sigma^-$ decay in flight, selected by setting momenta
larger than 275 MeV/$c$. The $\Sigma^-$ could be produced, together with a 500
MeV/$c$ proton, by the capture of a $K^-$ in a deuteron-cluster substructure of
the $^6$Li nucleus. The capture rate for such a reaction is $(1.62\pm
0.23_{stat} ^{+0.71}_{-0.44}(sys))%/K^-_{stop}$, in agreement with the existing
observations on $^4$He targets and with the hypothesis that the $^6$Li nucleus
can be interpreted as a $(d+\alpha)$ cluster.


title: Performance of HPGe Detectors in High Magnetic Fields

abstract:
  A new generation of high-resolution hypernuclear gamma$-spectroscopy
experiments with high-purity germanium detectors (HPGe) are presently designed
at the FINUDA spectrometer at DAPhiNE, the Frascati phi-factory, and at PANDA,
the antiproton proton hadron spectrometer at the future FAIR facility. Both,
the FINUDA and PANDA spectrometers are built around the target region covering
a large solid angle. To maximise the detection efficiency the HPGe detectors
have to be located near the target, and therefore they have to be operated in
strong magnetic fields B ~ 1 T. The performance of HPGe detectors in such an
environment has not been well investigated so far. In the present work VEGA and
EUROBALL Cluster HPGe detectors were tested in the field provided by the ALADiN
magnet at GSI. No significant degradation of the energy resolution was found,
and a change in the rise time distribution of the pulses from preamplifiers was
observed. A correlation between rise time and pulse height was observed and is
used to correct the measured energy, recovering the energy resolution almost
completely. Moreover, no problems in the electronics due to the magnetic field
were observed.


title: Low Mass Dimuon Production in Indium-Indium Collisions at the CERN SPS

abstract:
  NA60 is a fixed-target experiment at the CERN SPS which measured dimuon
production in nucleus-nucleus and proton-nucleus collisions. In this paper we
report on a precision measurement of low-mass muon pairs in 158 AGeV
indium-indium collisions. A significant excess of pairs is observed above the
yield expected from neutral meson decays. The excess can be isolated by
subtraction of expected sources, thanks to the excellent mass resolution and
large sample size.


title:
Computational studies of light acceptance and propagation in straight
  and curved multimodal active fibres

abstract:
  A Monte Carlo simulation has been performed to track light rays in
cylindrical multimode fibres by ray optics. The trapping efficiencies for skew
and meridional rays in active fibres and distributions of characteristic
quantities for all trapped light rays have been calculated. The simulation
provides new results for curved fibres, where the analytical expressions are
too complex to be solved. The light losses due to sharp bending of fibres are
presented as a function of the ratio of curvature to fibre radius and bending
angle. It is shown that a radius of curvature to fibre radius ratio of greater
than 65 results in a light loss of less than 10% with the loss occurring in a
transition region at bending angles of pi/8 rad.


title:
Azimuthal di-hadron correlations in Au+Au collisions at
  $\sqrt{s_{NN}}=200$ GeV from STAR

abstract:
  We present the centrality dependence of the azimuthal angle correlation
shapes between a trigger and associated charged hadrons in Au+Au collisions at
$\sqrt{s_{NN}}=200$ GeV from the STAR experiment. The away-side structure is
significantly modified in central collisions and is characterised in terms of a
doubly-peaked yield. A minimum in the <$p_T$> of hadrons opposite to the
trigger particle is also investigated.


title: Elliptic flow of Lambda hyperons in Pb+Pb collisions at 158A GeV

abstract:
  The elliptic flow of Lambda hyperons has been measured by the NA49
collaboration at the CERN-SPS in semi-central Pb+Pb collisions at 158A GeV. The
standard method of correlating particles with the event plane was used.
Measurements of v2 near mid-rapidity are reported as a function of rapidity,
centrality and transverse momentum. Elliptic flow of Lambda particles increases
both with the impact parameter and with the transverse momentum. It is compared
with v2 for pions and protons as well as with model calculations. The
observation of significant elliptic flow and its mass dependence suggest strong
collective behaviour of the matter produced in collisions of heavy nuclei
already at the SPS. Scaling properties of elliptic flow of different particle
species have been tested at 158A GeV. The limited pT range of the data does not
allow for a decisive test of the coalescence model.


title:
Observation of scattering and absorption centers in lead fluoride
  crystals

abstract:
  For the first time, lead fluoride is used as a fast and compact material in
electromagnetic calorimetry. Excellent optical and mechanical properties of the
pure Cherenkov crystals are necessary for the A4 collaboration to perform a
measurement of the nucleon's strange form factors. Visible scattering and
absorption centers as well as surface damages have been investigated to
characterize the quality of more than one thousand crystals. Besides,
transmittance measurements have been performed on all crystals to reveal
absorption bands produced by intrinsic or impurity related point-structure
defects. As a consequence, 89 crystals had to be replaced by the Chinese
manufacturer SICCAS.


title:
The multiplicity dependence of inclusive $p_t$ spectra from p-p
  collisions at $\sqrt{s}$ = 200 GeV

abstract:
  We report measurements of transverse momentum $p_t$ spectra for ten event
multiplicity classes of p-p collisions at $\sqrt{s} = 200$ GeV. By analyzing
the multiplicity dependence we find that the spectrum shape can be decomposed
into a part with amplitude proportional to multiplicity and described by a
L\'evy distribution on transverse mass $m_t$, and a part with amplitude
proportional to multiplicity squared and described by a gaussian distribution
on transverse rapidity $y_t$. The functional forms of the two parts are nearly
independent of event multiplicity. The two parts can be identified with the
soft and hard components of a two-component model of p-p collisions. This
analysis then provides the first isolation of the hard component of the $p_t$
spectrum as a distribution of simple form on $y_t$.


title:
Nuclear-matter modification of decay widths in the $\phi \to e^{+}e^{-}$
  and $\phi \to K^{+}K^{-}$ channels

abstract:
  The invariant mass spectra of $\phi \to K^{+}K^{-}$ are measured in 12 GeV
$p+A$ reactions in order to search for the in-medium modification of $\phi$
mesons. The observed $K^{+}K^{-}$ spectra are well reproduced by the
relativistic Breit-Wigner function with a combinatorial background shape in
three $\beta\gamma$ regions between 1.0 and 3.5. The nuclear mass-number
dependence of the yields of the $K^{+}K^{-}$ decay channel is compared to the
simultaneously measured $e^{+}e^{-}$ decay channel for carbon and copper
targets. We parameterize the production yields as $\sigma (A) = \sigma_0 \times
A^\alpha$ and obtain $\alpha_{\phi\to K^+K^-} - \alpha_{\phi\to e^+e^-}$ to be
0.14 $\pm$ 0.12. Limits are obtained for the partial decay widths of $\phi$
mesons in nuclear matter.


title: One-neutron knockout from $^{57}$Ni

abstract:
  The single-particle structure of $^{57}$Ni and level structure of $^{56}$Ni
were investigated with the \mbox{$^{9}$Be ($^{57}
$Ni,$^{56}$Ni+$\gamma$)$\it{X}$} reaction at 73 MeV/nucleon. An inclusive cross
section of 41.4(12) mb was obtained for the reaction, compared to a theoretical
prediction of 85.4 mb, hence only 48(2)% of the theoretical cross section is
exhausted. This reduction in the observed spectroscopic strength is consistent
with that found for lighter well-bound nuclei. One-neutron removal
spectroscopic factors of 0.58(11) to the ground state and 3.7(2) to all excited
states of $^{56}$Ni were deduced.


title:
Neutron to proton ratios of quasiprojectile and midrapidity emission in
  the $^{64}$Zn + $^{64}$Zn reaction at 45 MeV/nucleon

abstract:
  Simultaneous measurement of both neutrons and charged particles emitted in
the reaction $^{64}$Zn + $^{64}$Zn at 45 MeV/nucleon allows comparison of the
neutron to proton ratio at midrapidity with that at projectile rapidity. The
evolution of N/Z in both rapidity regimes with increasing centrality is
examined. For the completely re-constructed midrapidity material one finds that
the neutron-to-proton ratio is above that of the overall $^{64}$Zn + $^{64}$Zn
system. In contrast, the re-constructed ratio for the quasiprojectile is below
that of the overall system. This difference provides the most complete evidence
to date of neutron enrichment of midrapidity nuclear matter at the expense of
the quasiprojectile.


title:
Symmetry Energy, Temperature, Density and Isoscaling Parameter as a
  Function of Excitation energy in A $\sim$ 100 mass region

abstract:
  The symmetry energy, temperature, density and isoscaling parameter, in
$^{58}$Ni + $^{58}$Ni, $^{58}$Fe + $^{58}$Ni and $^{58}$Fe + $^{58}$Fe
reactions at beam energies of 30, 40 and 47 MeV/nucleon, are studied as a
function of excitation energy of the multifragmenting source. It is shown that
the decrease in the isoscaling parameter is related to the near flattening of
the temperature in the caloric curve, and the decrease in the density and the
symmetry energy with increasing excitation energy. The decrease in the symmetry
energy is mainly a consequence of decreasing density with increasing excitation
rather than the increasing temperature. The symmetry energy as a function of
density obtained from the correlation is in close agreement with the form,
E$_{sym}(\rho)$ $=$ 31.6 ($\rho/\rho_{\circ})^{0.69}$.


title: Cross-shell excitation in two-proton knockout: Structure of $^{52}$Ca

abstract:
  The two-proton knockout reaction $^9$Be($^{54}$Ti,$^{52}$Ca$ + \gamma$) has
been studied at 72 MeV/nucleon. Besides the strong feeding of the $^{52}$Ca
ground state, the only other sizeable cross section proceeds to a 3$^-$ level
at 3.9 MeV. There is no measurable direct yield to the first excited 2$^+$
state at 2.6 MeV. The results illustrate the potential of such direct reactions
for exploring cross-shell proton excitations in neutron-rich nuclei and
confirms the doubly-magic nature of $^{52}$Ca.


title: An Experimental Overview of Results Presented at SQM 2006

abstract:
  I have been asked to give an critical overview on the experimental results
shown in the conference with a emphasis of what has been learned and the
challenges that are ahead in trying to understand the physics of the strongly
interacting quark-gluon plasma. I will not try to summarize all of the results
presented, rather I will concentrate primarily on RHIC data from this
conference. Throughout this summary, I will periodically review some of the
previous results for those not familiar with the present state of the field.


title:
Q-values of the Superallowed beta-Emitters 26m-Al, 42-Sc and 46-V and
  their impact on V_ud and the Unitarity of the CKM Matrix

abstract:
  The beta-decay Q_EC-values of the superallowed beta emitters 26m-Al, 42-Sc
and 46-V have been measured with a Penning trap to a relative precision of
better than 8x10^-9. Our result for 46-V, 7052.72(31) keV, confirms a recent
measurement that differed significantly from the previously accepted
reaction-based Q_EC-value. However, our results for 26m-Al and 42-Sc,
4232.83(13) keV and 6426.13(21) keV, are consistent with previous
reaction-based values. By eliminating the possibility of a systematic
difference between the two techniques, this result demonstrates that no
significant shift in the deduced value of V_ud should be anticipated.


title:
Precision measurement of the quasi-free pn->dphi reaction close to
  threshold

abstract:
  The quasi-free pn->dphi reaction has been studied at the Cooler Synchrotron
COSY-Juelich, using the internal proton beam incident on a deuterium
cluster-jet target and detecting a fast deuteron in coincidence with the K+K-
decay of the phi-meson. The energy dependence of the total and differential
cross sections are extracted for excess energies up to 80 MeV by determining
the Fermi momentum of the target neutron on an event-by-event basis. Though
these cross sections are consistent with s-wave production, the kaon angular
distributions show the presence of p waves at quite low energy. Production on
the neutron is found to be stronger than on the proton but not by as much as
for the eta-meson.


title:
Evidence of the Coulomb force effects in the cross sections of the
  deuteron-proton breakup at 130 MeV

abstract:
  High precision cross-section data of the deuteron-proton breakup reaction at
130 MeV deuteron energy are compared with the theoretical predictions obtained
with a coupled-channel extension of the CD Bonn potential with virtual
Delta-isobar excitation, without and with inclusion of the long-range Coulomb
force. The Coulomb effect is studied on the basis of the cross-section data
set, extended in this work to about 1500 data points by including breakup
geometries characterized by small polar angles of the two protons. The
experimental data clearly prefer predictions obtained with the Coulomb
interaction included. The strongest effects are observed in regions in which
the relative energy of the two protons is the smallest.


title:
Delta- phi Delta- eta Correlations in Central Au+Au Collisions at
  sqrt{s_{NN}} = 200 Gev

abstract:
  We report charged-particle pair correlation analyses in the space of Delta
-phi (azimuth) and Delta -eta (pseudo-rapidity), for central Au + Au collisions
at sqrt{s_{NN}} = 200 GeV in the STAR detector. The analysis involves
unlike-sign charge pairs and like-sign charge pairs, which are transformed into
charge-dependent (CD) signals and charge-independent (CI) signals. We present
detailed parameterizations of the data. A model featuring dense gluonic hot
spots as first proposed by van Hove predicts that the observables under
investigation would have sensitivity to such a substructure should it occur,
and the model also motivates selection of transverse momenta in the range 0.8 <
p_t < 2.0$ GeV/c. Both CD and CI correlations of high statistical significance
are observed and possible interpretations are discussed.


title:
Transverse dynamics of Pb-Pb collisions at 40 A GeV/c viewed by strange
  hadrons

abstract:
  The transverse mass spectra of K0s, Lambda, Xi and Omega particles produced
in Pb-Pb collisions at 40 A GeV/c have been studied for a sample of events
corresponding to the most central 53% of the inelastic Pb-Pb cross-section. We
analyze the distributions in the framework of a parameterized model inspired by
hydrodynamics. The dependence of the freeze-out parameters on particle species
and event centrality is discussed and comparisons with results at higher energy
are shown.


title:
Determination of the Charged Pion Form Factor at Q2=1.60 and 2.45
  (GeV/c)2

abstract:
  The H(e,e'pi+)n cross section was measured at four-momentum transfers of
Q2=1.60 and 2.45 GeV2 at an invariant mass of the photon nucleon system of
W=2.22 GeV. The charged pion form factor (F_pi) was extracted from the data by
comparing the separated longitudinal pion electroproduction cross section to a
Regge model prediction in which F_pi is a free parameter. The results indicate
that the pion form factor deviates from the charge-radius constrained monopole
form at these values of Q2 by one sigma, but is still far from its perturbative
Quantum Chromo-Dynamics prediction.


title:
Measurement of helium-3 and deuterium stopping power ratio for negative
  muons

abstract:
  The measurement method and results measuring of the stopping power ratio of
helium-3 and deuterium atoms for muons slowed down in the D/$^3$He mixture are
presented. Measurements were performed at four values of pure $^3$He gas target
densities, $\phi_{He} = 0.0337, 0.0355, 0.0359, 0.0363$ (normalized to the
liquid hydrogen density) and at a density 0.0585 of the D/$^3$He mixture. The
experiment was carried out at PSI muon beam $\mu$E4 with the momentum P$\mu
=34.0$ MeV/c. The measured value of the mean stopping ratio $S_{^3He/D}$ is
$1.66\pm 0.04$. This value can also be interpreted as the value of mean reduced
ratio of probabilities for muon capture by helium-3 and deuterium atoms.


title: Determination of the pion charge form factor for Q^2=0.60-1.60 GeV^2

abstract:
  The data analysis for the reaction H(e,e' pi^+)n, which was used to determine
values for the charged pion form factor Fpi for values of Q^2=0.6-1.6 GeV^2,
has been repeated with careful inspection of all steps and special attention to
systematic uncertainties. Also the method used to extract Fpi from the measured
longitudinal cross section was critically reconsidered. Final values for the
separated longitudinal and transverse cross sections and the extracted values
of Fpi are presented.


title: d+Au Collisions at STAR

abstract:
  STAR has measured forward pi^0 production in p+p and d+Au collisions at
sqrt{s_{NN}}=200 GeV. The p+p yield generally agrees with NLO pQCD
calculations. The d+Au yield is strongly suppressed at <eta>=4.0, well below
shadowing expectations. Exploratory measurements of azimuthal correlations
between forward pi^0 and mid-rapidity charged hadrons show a recoil peak in p+p
that is suppressed in d+Au at low pion energy. These observations are
qualitatively consistent with a saturation picture of the low-x gluon structure
of heavy nuclei. Future measurements to elucidate the dynamics underlying these
observations are also described.


title: High-pT Particle Production with Respect to the Reaction Plane

abstract:
  The PHENIX Run4 data-set provides a powerful opportunity for exploring the
angular anisotropy of identified particle yields at high pT. Complementing
traditional v2 measurements, we present pi0 yields as a function of emission
angle with respect to the reaction plane in Au+Au collisions at sqrt(s) = 200
GeV/c. The centrality dependence of the angular anisotropy allows us to probe
the density and path-length dependence of the energy loss of hard-scattered
partons.


title: Quarkonia production at RHIC

abstract:
  Quarkonia (J/Psi, Psi', Upsilon) production provides a sensitive probe of
gluon distributions and their modification in nuclei; and is a leading probe of
the hot-dense (deconfined) matter created in high-energy collisions of heavy
ions. I will discuss our current understanding of the modification of gluon
distributions in nuclei and other cold-nuclear-matter effects in the context of
recent p-p and p(d)-A quarkonia measurements. Then I will review the latest
results for nucleus-nucleus collisions from RHIC, and together with the
baseline results from d-A and p-p collisions, discuss several alternative
explanations for the observed suppressions and future prospects for
distinguishing these different pictures.


title: Open charm production in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions

abstract:
  We report on the measurement of D meson production from the analysis of their
hadronic ($D^0\to K\pi$) and semileptonic ($D\to \mu+X$, $D\to e+X$) decays in
$\sqrt{s_{NN}}$=200 GeV Au+Au collisions. The transverse momentum ($p_T$)
spectra and the nuclear modification factors for $D^0$ and for electron/muon
from charm semileptonic decays will be presented. The differential cross
section $d\sigma/dy$ is found to be consistent with the number of binary
scaling. The blast-wave fit suggests that the charm hadron freeze out earlier
than other light flavor hadrons.


title:
Erratum: Transverse momentum and centrality dependence of high-\pt\
  non-photonic electron suppression in Au+Au collisions at \sqrtsNN\ = 200 GeV

abstract:
  The STAR collaboration at RHIC reports measurements of the inclusive yield of
non-photonic electrons, which arise dominantly from semi-leptonic decays of
heavy flavor mesons, over a broad range of transverse momenta ($1.2 < \pt < 10$
\gevc) in \pp, \dAu, and \AuAu collisions at \sqrtsNN = 200 GeV. The
non-photonic electron yield exhibits unexpectedly large suppression in central
\AuAu collisions at high \pt, suggesting substantial heavy quark energy loss at
RHIC. The centrality and \pt dependences of the suppression provide constraints
on theoretical models of suppression.

  at RHIC

abstract:
  PHENIX preliminary results on the $J/\Psi$ production in $Cu+Cu$ and $Au+Au$
collisions at $\sqrt{s_{NN}}=200$ GeV are presented. They are compared to
results from lower energy experiments NA50 and NA60 at CERN SPS and to
expectations from various theoretical models.

Results from the Analysis of Crystal Ball Meson Production Measurements
  at BNL

abstract:
  The Crystal Ball spectrometer, with its nearly complete angular coverage, is
an efficient detector of photon and neutron final states. While installed in
the C6 beamline of the Alternating Gradient Synchrotron (AGS) of Brookhaven
National Laboratory (BNL), this feature was used in a series of precise
measurements of reactions with all-neutral final states. Here we concentrate on
the analysis of data from the pion-induced reactions: pi- p --> gamma n, pi- p
--> pi0 n, pi- p --> eta n, and pi- p --> pi0 pi0 n.


title: Overview of charm production at RHIC

abstract:
  In this presentation, I discussed a) the charm total cross-section and its
comparisons to measurements at other beam energies and pQCD calculations; b)
the semileptonic decay of charmed hadrons and the sensitivity of non-photonic
leptons to charm quark collective flow and freeze-out; c) semileptonic decayed
electron spectrum at high transverse momentum, its comparison to FONLL in p+p
and d+Au collisions, and heavy-quark energy loss in Au+Au collisions.


title:
Neutron and Proton Transverse Emission Ratio Measurements and the
  Density Dependence of the Asymmetry Term of the Nuclear Equation of State

abstract:
  Recent measurements of pre-equilibrium neutron and proton transverse emission
from (112,124)Sn+(112,124)Sn reactions at 50 MeV/A have been completed at the
National Superconducting Cyclotron Laboratory. Free nucleon transverse emission
ratios are compared to those of A=3 mirror nuclei. Comparisons are made to BUU
transport calculations and conclusions concerning the density dependence of the
asymmetry term of the nuclear equation-of-state at sub-nuclear densities are
made. The double-ratio of neutron-proton ratios between two reactions is
employed as a means of reducing first-order Coulomb effects and detector
efficiency effects. Comparison to BUU model predictions indicate a density
dependence of the asymmetry energy that is closer to a form in which the
asymmety energy increases as the square root of the density for the density
region studied. A coalescent-invariant analysis is introduced as a means of
reducing suggested difficulties with cluster emission in total nucleon
emission. Future experimentation is presented.


title:
Two-neutron knockout from neutron-deficient $^{34}$Ar, $^{30}$S, and
  $^{26}$Si

abstract:
  Two-neutron knockout reactions from nuclei in the proximity of the proton
dripline have been studied using intermediate-energy beams of neutron-deficient
$^{34}$Ar, $^{30}$S, and $^{26}$Si. The inclusive cross sections, and also the
partial cross sections for the population of individual bound final states of
the $^{32}$Ar, $^{28}$S and $^{24}$Si knockout residues, have been determined
using the combination of particle and $\gamma$-ray spectroscopy. Similar to the
two-proton knockout mechanism on the neutron-rich side of the nuclear chart,
these two-neutron removal reactions from already neutron-deficient nuclei are
also shown to be consistent with a direct reaction mechanism.


title:
Pion Freeze-Out Time in Pb+Pb Collisions at 158 A GeV/c Studied via
  pi-/pi+ and K-/K+ Ratios

abstract:
  The effect of the final state Coulomb interaction on particles produced in
Pb+Pb collisions at 158 A GeV/c has been investigated in the WA98 experiment
through the study of the pi-/pi+ and K-/K+ ratios measured as a function of
transverse mass. While the ratio for kaons shows no significant transverse mass
dependence, the pi-/pi+ ratio is enhanced at small transverse mass values with
an enhancement that increases with centrality. A silicon pad detector located
near the target is used to estimate the contribution of hyperon decays to the
pi-/pi+ ratio. The comparison of results with predictions of the RQMD model in
which the Coulomb interaction has been incorporated allows to place constraints
on the time of the pion freeze-out.


title:
Production of $^{6}_{\Lambda}$H and $^{7}_{\Lambda}$H with the
  (K$^{-}_{stop}$,$\pi^+$) reaction

abstract:
  The production of neutron rich $\Lambda$-hypernuclei via the
($K^-_stop$,$\pi^+$) reaction has been studied using data collected with the
FINUDA spectrometer at the DA$\Phi$NE $\phi$-factory (LNF). The analysis of the
inclusive $\pi^+$ momentum spectra is presented and an upper limit for the
production of $^6_\Lambda$H and $^7_\Lambda$H from $^6$Li and $^7$Li, is
assessed for the first time.


title:
Linear electric field frequency shift (important for next generation
  electric dipole moment searches) induced in confined gases by a magnetic
  field gradient

abstract:
  The search for particle electric dipole moments (edm) represents a most
promising way to search for physics beyond the standard model. A number of
groups are planning a new generation of experiments using stored gases of
various kinds. In order to achieve the target sensitivities it will be
necessary to deal with the systematic error resulting from the interaction of
the well-known $\overrightarrow{v}\times \overrightarrow{E}$ field with
magnetic field gradients (often referred to as the geometric phase effect
(Commins, ED; Am. J. Phys. \QTR{bf}{59}, 1077 (1991), Pendlebury, JM
\QTR{em}{et al;} Phys. Rev. \QTR{bf}{A70}, 032102 (2004)). This interaction
produces a frequency shift linear in the electric field, mimicking an edm. In
this work we introduce an analytic form for the velocity auto-correlation
function which determines the velocity-position correlation function which in
turn determines the behavior of the frequency shift (Lamoreaux, SK and Golub,
R; Phys. Rev \QTR{bf}{A71}, 032104 (2005)) and show how it depends on the
operating conditions of the experiment. We also discuss some additional issues.


title:
Centrality Dependence of Azimuthal Anisotropy of Strange Hadrons in 200
  GeV Au+Au Collisions

abstract:
  Measurements of azimuthal anisotropy for strange and multi-strange hadrons
are presented for the first time in their centrality dependence. The high
statistics results of v2(pT) allow for a more detailed comparison to
hydrodynamical model calculations. Number-of-constituent-quark scaling was
tested for different centrality classes separately. Higher order anisotropies
like v4(pT) are measured for multi-strange hadrons. While we observe agreement
between measured data and models a deeper understanding and refinement of the
models seem to be necessary in order to fully understand the details of the
data.


title: Photo-production of neutral kaons on 12C in the threshold region

abstract:
  Kaon photo-production process on $^{12}$C has been studied by measuring
neutral kaons in a photon energy range of 0.8$-$1.1 GeV. Neutral kaons were
identified by the invariant mass constructed from two charged pions emitted in
the $K^{0}_{S}\to\pi^{+}\pi^{-}$ decay channel. The differential cross sections
as well as the integrated ones in the threshold photon energy region were
obtained. The obtained momentum spectra were compared with a Spectator model
calculation using elementary amplitudes of kaon photo-production given by
recent isobar models. Present result provides, for the first time, the
information on $n(\gamma,K^{0})\Lambda$ reaction which is expected to play an
important role to construct models for strangeness production by the
electromagnetic interaction. Experimental results show that cross section of
$^{12}{\rm C}(\gamma,K^0)$ is of the same order to that of $^{12}{\rm
C}(\gamma,K^+)$ and suggest that slightly backward $K^0$ angular distribution
is favored in the $\gamma n\to K^0\Lambda$ process.

Comment to "Observation of the neutron radiative decay" by R.U. Khafizov
  et al., published in JETP Letters 83 (2006) 5 (Pis'ma v ZhETF 83 (2006) 7)

abstract:
  The commented manuscript was submitted for publication without informing at
least four of the other authors, viz. N. Severijns, O. Zimmer, H.-F. Wirth and
D. Rich. This violates our rights as collaborators. The analysis presented and
the manuscript itself have not been discussed and have also not been approved
by the entire collaboration prior to submission. Besides this formal
incorrectness, we also criticise the content of the paper.


title:
Measurement of Neutron Background at the Pyhasalmi mine for CUPP
  Project, Finland

abstract:
  A natural neutron flux is one of significant kind of background in
high-sensitive underground experiments. Therefore, when scheduling a delicate
underground measurements one needs to measure neutron background. Deep
underground the most significant source of neutrons are the U-Th natural
radioactive chains giving a fission spectrum with the temperature of 2-3 MeV.
Another source is the U-Th alpha-reactions on light nuclei of mine rock giving
neutrons with different spectra in the 1-15 MeV energy region. Normal basalt
mine rocks contain 1 ppm g/g of U-238 and less. Deep underground those rocks
produce natural neutron fluxes of 10^{-7} - 10^{-6} cm^{-2}s^{-1} above 1 MeV.
To measure such a background one needs a special techniques. In the Institute
for Nuclear Research, Moscow, the neutron spectrometer was developed and built
which is sensitive to such a low neutron fluxes. At the end of 2001 the
collection of neutron data at the Pyhasalmi mine was started for the CUPP
project. During 2002 the background and rough energy spectra of neutron at
underground levels 410, 660, 990 and 1410 m were measured. The result of the
measurement of the neutron background at different levels of the Pyhasalmi mine
is presented and discussed. Data analysis is performed in different energy
ranges from thermal neutrons up to 25 MeV and above.


title: N=90 region: The decays of {152m,g}Eu to 152Sm

abstract:
  The decays of {152m,g}Eu to 152Sm have been studied by gamma-ray spectroscopy
using the 8pi Spectrometer, an array of 20 Compton-suppressed Ge detectors.
Very weak gamma-decay branches in 152Sm were investigated through gamma-gamma
coincidence spectroscopy. All possible E2 transitions between states below 1550
keV with transition energies > 130 keV are observed, including the previously
unobserved 2^+_3 to 0^+_2 401 keV transition. The results, combined with
existing lifetime data, provide a number of new or revised E2 transition
strengths which are critical for clarifying the collective structure of 152Sm
and the N=90 isotones.


title:
Identification of mixed-symmetry states in an odd-mass nearly-spherical
  nucleus

abstract:
  The low-spin structure of 93Nb has been studied using the (n,n' gamma)
reaction at neutron energies ranging from 1.5 to 3.0 MeV and the 94Zr(p,2n
gamma)93Nb reaction at bombarding energies from 11.5 to 19 MeV. States at
1779.7 and 1840.6 keV, respectively, are proposed as mixed-symmetry states
associated with the coupling of a proton hole in the p_1/2 orbit to the 2+_1,ms
state in 94Mo. These assignments are derived from the observed M1 and E2
transition strengths to the symmetric one-phonon states, energy systematics,
spins and parities, and comparison with shell model calculations.


title:
Observation of New Resonance Structure in the Invariant Mass Spectrum of
  Two gamma-Quanta in dC-Interactions at Momentum 2.75 GeV/c per Nucleon

abstract:
  A new resonance structure at M = 355 \pm 6 \pm 9 MeV is observed in the
invariant mass spectrum of two gamma-quanta produced in the reaction d + C =>
gamma + gamma + x at momentum 2.75 GeV/c per nucleon. Preliminary estimates of
its width and cross section are Gamma = 41 \pm 12 MeV and sigma_{gamma-gamma} =
0.6 mkb. The collected statistics is 2680 \pm 310 events of 1.5 10^6 triggered
interactions of a total number 3 10^{12} dC-interactions.


title: Tidal effects and the Proximity decay of nuclei

abstract:
  We examine the decay of the 3.03 MeV state of $^8$Be evaporated from an
excited projectile-like fragment following a peripheral heavy-ion collision.
The relative energy of the daughter $\alpha$ particles exhibits a dependence on
the decay angle of the $^8$Be$^*$, indicative of a tidal effect. Comparison of
the measured tidal effect with a purely Coulomb model suggests the influence of
a measurable nuclear proximity interaction.


title: Scaling Tests of the Cross Section for Deeply Virtual Compton Scattering

abstract:
  We present the first measurements of the \vec{e}p->epg cross section in the
deeply virtual Compton scattering (DVCS) regime and the valence quark region.
The Q^2 dependence (from 1.5 to 2.3 GeV^2) of the helicity-dependent cross
section indicates the twist-2 dominance of DVCS, proving that generalized
parton distributions (GPDs) are accessible to experiment at moderate Q^2. The
helicity-independent cross section is also measured at Q^2=2.3 GeV^2. We
present the first model-independent measurement of linear combinations of GPDs
and GPD integrals up to the twist-3 approximation.


title: critRHIC: The RHIC Low Energy Program

abstract:
  Recent experimental and theoretical developments have motivated interest in a
more detailed exploration of heavy ion collisions in the range sqrt(sNN)=5-15
GeV. In contrast to interactions at the full RHIC energy of sqrt(sNN)=200 GeV,
such collisions result in systems characterized by much higher baryon chemical
potential, muB. Extensions of lattice QCD calculations to non-zero values of
muB suggest that a critical point may exist in this region of the QCD phase
diagram. Discovery of the critical point or, equivalently, determining the
location where the phase transition from partonic to hadronic matter switches
from a smooth crossover to 1st order would establish a major landmark in the
phase diagram. Initial studies of Pb+Pb collisions in this energy range have
revealed several unexpected features in the data. In response to these results,
it has been suggested that the existing RHIC accelerator and experiments can be
used to further the investigation of this important physics topic. This
proceeding briefly summarizes the theoretical and experimental situation with
particular emphasis on the conclusions from a RIKEN BNL workshop held in March
of 2006.


title: Heavy Flavor Production at STAR

abstract:
  e present measurements on $D^0$ meson production via direct reconstruction of
its hadronic decay channel $D^0\to K\pi$ in minimum bias $d$+Au and Au+Au
collisions at $\sqrt{s_{NN}}$=200 GeV with $p_T$ up to $\sim$3 GeV/$c$.
Non-photonic electron spectra from the charm semi-leptonic decays are analyzed
from the same data set as well as in $p$+$p$ collision at $\sqrt{s}$=200 GeV
using the STAR Time-of-Flight (TOF) and Barrel EMC (BEMC) detectors,
respectively. Results of the charm-decayed single muon (prompt muon) spectra
are also presented at low $p_T$ in Au+Au collisions measured by the TOF
detector. The charm production total cross-section per nucleon-nucleon
collision is measured to be 1.26$\pm$0.09(stat.)$\pm$0.23(sys.) mb in minimum
bias Au+Au collisions, which is consistent with the $N_{bin}$ scaling compared
to 1.4$\pm0.2\pm$0.4 mb in minimum bias $d$+Au collisions, and supports the
idea that charm quarks should be produced mostly via parton fusion at early
stage in relativistic heavy-ion collisions. A Blast-Wave model fit to the low
$p_T$ ($<2$ GeV/c) non-photonic electrons, prompt muons and $D^0$ spectra shows
that charm hadrons may kinetically freeze-out earlier than light hadrons with a
smaller collective velocity. The nuclear modification factors ($R_{AA}$) of the
non-photonic electrons in central Au+Au collisions are significantly below
unity at $p_T>\sim$2 GeV/$c$, which indicates a significant amount of energy
loss for heavy quarks in Au+Au collisions. The charm transverse momentum
distribution must have been modified by the hot and dense matter created in
central Au+Au collisions at RHIC.


title: Radiation shielding for underground low-background experiments

abstract:
  The design task of creating an efficient radiation shield for the new COBRA
double-beta decay experiment led to a comprehensive study of commercially
available shielding materials. The aim was to find the most efficient
combination of materials under the constraints of an extreme low-background
experiment operating in a typical underground laboratory. All existing shield
configurations for this type of experiment have been found to perform
sub-optimally in comparison to the class of multilayered configurations
proposed in this study. The method used here to create a specific shield
configuration should yield a close to optimal result when applied to any
experiment utilising a radiation shield. In particular, the survey of single
material response to a given radiation source turns out to give a guideline for
the construction of efficient multilayer shields.


title:
Measurements of Strange Particle Production in $p+p$ Collisions at
  $\sqrt{s}$= 200 GeV

abstract:
  We present strange particle spectra and yields measured at mid-rapidity in
$\sqrt{\text{s}}=200$ GeV proton-proton ($p+p$) collisions at RHIC. We find
that the previously observed universal transverse mass
($\mathrm{m_{T}}\equiv\sqrt{\mathrm{p_{T}}^{2}+\mathrm{m}^{2}}$) scaling of
hadron production in $p+p$ collisions seems to break down at higher \mt and
that there is a difference in the shape of the \mt spectrum between baryons and
mesons. We observe mid-rapidity anti-baryon to baryon ratios near unity for
$\Lambda$ and $\Xi$ baryons and no dependence of the ratio on transverse
momentum, indicating that our data do not yet reach the quark-jet dominated
region. We show the dependence of the mean transverse momentum (\mpt) on
measured charged particle multiplicity and on particle mass and infer that
these trends are consistent with gluon-jet dominated particle production. The
data are compared to previous measurements from CERN-SPS, ISR and FNAL
experiments and to Leading Order (LO) and Next to Leading order (NLO) string
fragmentation model predictions. We infer from these comparisons that the
spectral shapes and particle yields from $p+p$ collisions at RHIC energies have
large contributions from gluon jets rather than quark jets.


title: Threshold hyperon production in proton-proton collisions at COSY-11

abstract:
  Sigma+ hyperon production was measured at the COSY-11 spectrometer via the p
p --> n K+ Sigma+ reaction at excess energies of Q = 13 MeV and Q = 60 MeV.
These measurements continue systematic hyperon production studies via the p p
--> p K+ Lambda/Sigma0 reactions where a strong decrease of the cross section
ratio close-to-threshold was observed. In order to verify models developed for
the description of the Lambda and Sigma0 production we have performed the
measurement on the Sigma+ hyperon and found unexpectedly that the total cross
section is by more than one order of magnitude larger than predicted by all
anticipated models.
  After the reconstruction of the kaon and neutron four momenta, the Sigma+ is
identified via the missing mass technique. Details of the method and the
measurement will be given and discussed in view of theoretical models.


title: The beta-decay of 22Al

abstract:
  In an experiment performed at the LISE3 facility of GANIL, we studied the
decay of 22Al produced by the fragmentation of a 36Ar primary beam. A
beta-decay half-life of 91.1 +- 0.5 ms was measured. The beta-delayed one- and
two-proton emission as well as beta-alpha and beta-delayed gamma decays were
measured and allowed us to establish a partial decay scheme for this nucleus.
New levels were determined in the daughter nucleus 22Mg. The comparison with
model calculations strongly favours a spin-parity of 4+ for the ground state of
22Al.


title: Methods for Jet Studies with Three-Particle Correlations

abstract:
  We present a method based on three-particle azimuthal correlation cumulants
for studying jet interactions with the medium produced in heavy ion collisions
(at RHIC) where jets cannot be reconstructed on an event-by-event basis with
conventional jet-finding algorithms. The method is specifically designed to
distinguish a range of jet interaction mechanisms such as Mach cone emission,
gluon Cerenkov emission, jet scattering, and jet broadening. We describe how
anisotropic flow contributions of second order (e.g. v22) are suppressed in
three-particle azimuthal correlation cumulants, and discuss specific model
representations of di-jets, away-side scattering, and Mach cone emission.


title: Proton Spin Structure in the Resonance Region

abstract:
  We have examined the spin structure of the proton in the region of the
nucleon resonances (1.085 GeV < W < 1.910 GeV) at an average four momentum
transfer of Q^2 = 1.3 GeV^2. Using the Jefferson Lab polarized electron beam, a
spectrometer, and a polarized solid target, we measured the asymmetries
A_parallel and A_perp to high precision, and extracted the asymmetries A_1 and
A_2, and the spin structure functions g_1 and g_2. We found a notably non-zero
A_perp, significant contributions from higher-twist effects, and only weak
support for polarized quark--hadron duality.


title:
Further study of CdWO4 crystal scintillators as detectors for high
  sensitivity double beta experiments: scintillation properties and pulse-shape
  discrimination

abstract:
  Energy resolution, light yield, non-proportionality in the scintillation
response, alpha/beta ratio, pulse shape for gamma rays and alpha particles were
studied with CdWO4 crystal scintillators. Some indication for a difference in
the emission spectra for gamma rays and alpha particles was observed. No
dependence of CdWO4 pulse shape on emission spectrum wavelengths under laser,
alpha particles and gamma ray excitation was observed. Dependence of
scintillation pulse shape for gamma quanta and alpha particles and pulse-shape
discrimination ability on temperature was measured in the range of 0-24
degrees.


title:
ALICE perspectives for the study of charm and beauty energy loss at the
  LHC

abstract:
  At LHC energy, heavy quarks will be abundantly produced and the design of the
ALICE detector will allow us to study their production using several channels.
The expected heavy-quark in-medium energy loss in nucleus-nucleus collisions at
the LHC is calculated within a model, that is compared to the available
heavy-quark quenching measurements at RHIC. The nuclear modification factors
and heavy-to-light ratios of charm and beauty mesons are considered. The
capability of the ALICE experiment for addressing this phenomenology is
discussed.


title:
Upper Bounds on Parity Violating Gamma-Ray Asymmetries in Compound
  Nuclei from Polarized Cold Neutron Capture

abstract:
  Parity-odd asymmetries in the electromagnetic decays of compound nuclei can
sometimes be amplified above values expected from simple dimensional estimates
by the complexity of compound nuclear states. In this work we use a statistical
approach to estimate the root mean square (RMS) of the distribution of expected
parity-odd correlations $\vec{s_{n}} \cdot \vec{k_{\gamma}}$, where $\vec
{s_{n}}$ is the neutron spin and $\vec{k_{\gamma}}$ is the momentum of the
gamma, in the integrated gamma spectrum from the capture of cold polarized
neutrons on Al, Cu, and In and we present measurements of the asymmetries in
these and other nuclei. Based on our calculations, large enhancements of
asymmetries were not predicted for the studied nuclei and the statistical
estimates are consistent with our measured upper bounds on the asymmetries.


title: The Giant Monopole Resonance in the Sn Isotopes: Why is Tin so "Fluffy"?

abstract:
  The isoscalar giant monopole resonance (GMR) has been investigated in a
series of Sn isotopes (A=112--124) using inelstic scattering of 400-MeV alpha
particles at extremely forward angles (including 0deg). The primary aim of the
investigation has been to explore the role of the "symmetry-energy" term in the
expression for nuclear incompressibility. It is found that the energies of the
GMR in the Sn isotopes are significantly lower than those expected from the
nuclear incompressibility previously extracted from the available data on the
compressional-mode giant resonances.


title: Strange hadrons as dense matter probes

abstract:
  The spectra of strange hadrons have been measured in detail as a function of
centrality for a variety of collision systems and energies at RHIC. Recent
results are presented and compared to those measured at the SPS. The effects of
the system size on strange particle production and kinematics are examined. I
place specific emphasis on comparing A-A to pp production and discuss how
strangeness can be used to probe the dense matter produced in heavy-ion
collisions.


title:
Measurement of photons via conversion pairs in \sqrt{s_{NN}} = 200 GeV
  Au+Au collisions with the PHENIX experiment at RHIC

abstract:
  Thermal photons can provide information on the temperature of the new state
of matter created at RHIC. In the p_T region of 1--3 GeV/c thermal photons are
expected to be the dominant direct photon source. Therefore, a possible excess
compared to a pure decay photon signal due to a thermal photon contribution
should be seen in the double ratio
(\gamma/\gamma(\pi^{0}))_{Measured}/(\gamma/\gamma(\pi^{0}))_{Simulated}, if
sufficient accuracy can be reached. We present a method to reconstruct direct
photons by measuring e^{+}e^{-}--pairs from external photon conversions.


title:
Measurement of low mass dielectron continuum in sqrt(s_{NN}) = 200 GeV
  Au+Au collisions in the PHENIX Experiment at RHIC

abstract:
  The first measurement of the dielectron continuum at RHIC energies was
performed by the PHENIX experiment for Au+Au collisions at sqrt(s_{NN}) = 200
GeV. Mass spectra for different centralities are presented and compared with
the expectations from hadron decays.


title:
Deformation Effects in Hot Rotating 46Ti Probed by the Charged Particle
  Emission and GDR gamma-Decay

abstract:
  The 46Ti* compound nucleus, as populated by the fusion-evaporation reaction
27Al+19F at the bombarding energy of E_lab=144 MeV, has been investigated by
charged particle spectroscopy using the multidetector array ICARE at the
VIVITRON tandem facility of the IReS (Strasbourg). The light charged particles
and high-energy gamma-rays from the GDR decay have been measured in coincidence
with selected evaporation residues. The CACARIZO code, a Monte Carlo
implementation of the statistical-model code CASCADE, has been used to
calculate the spectral shapes of evaporated alpha-particles which are compared
with the experimental coincident spectra. This comparison indicates the
signature of large deformations (possibly superdeformed and hyperdeformed
shapes) present in the compound nucleus decay. The occurrence of the Jacobi
shape transition is also discussed in the framework of a newly developed
rotating liquid drop model.


title: Neutral Kaon Interferometry in Au+Au collisions at sqrt(s_NN) = 200 GeV

abstract:
  We present the first statistically meaningful results from two-K0s
interferometry in heavy-ion collisions. A model that takes the effect of the
strong interaction into account has been used to fit the measured correlation
function. The effects of single and coupled channel were explored. At the mean
transverse mass m_T = 1.07 GeV, we obtain the values R = 4.09 +/- 0.46 (stat.)
+/- 0.31 (sys) fm and lambda = 0.92 +/- 0.23 (stat) +/- 0.13 (sys), where R and
lambda are the invariant radius and chaoticity parameters respectively. The
results are qualitatively consistent with m_T systematics established with
pions in a scenario characterized by a strong collective flow.


title: Inclusive Electron Scattering From Nuclei at x>1 and High Q^2

abstract:
  CEBAF experiment e89-008 measured inclusive electron scattering from nuclei
in a Q^2 range between 0.8 and 7.3 (GeV/c)^2 for x_{Bjorken} \gtorder 1. The
cross sections for scattering from D, C, Fe, and Au were measured. The C, Fe,
and Au data have been analyzed in terms of F(y) to examine $y$-scaling of the
quasielastic scattering, and to study the momentum distribution of the nucleons
in the nucleus. The data have also been analyzed in terms of the structure
function \nu W_2 to examine scaling of the inelastic scattering in x and \xi,
and to study the momentum distribution of the quarks. In the regions where
quasielastic scattering dominates the cross section (low Q^2 or large negative
values of y), the data are shown to exhibit y-scaling. However, the y-scaling
breaks down once the inelastic contributions become large. The data do not
exhibit x-scaling, except at the lowest values of x, while the structure
function does appear to scale in the Nachtmann variable, \xi.


title:
Evolution of the $E(1/2^+_1)-E(3/2^+_1)$ energy spacing in odd-mass K,
  Cl and P isotopes for $N=20-28$

abstract:
  The energy of the first excited state in the neutron-rich N=28 nucleus 45Cl
has been established via in-beam gamma-ray spectroscopy following proton
removal. This energy value completes the systematics of the
E(1/2^+_1)-E(3/2^+_1) level spacing in odd-mass K, Cl and P isotopes for
N=20-28. The results are discussed in the framework of shell-model calculations
in the sd-fp model space. The contribution of the central, spin-orbit and
tensor components is discussed from a calculation based on a proton single-hole
spectrum from G-matrix and pi + rho meson exchange potentials. A composite
model for the proton 0d_{3/2}-1s_{1/2} single-particle energy shift is
presented.


title: Systematics of Stopping and Flow in Au+Au Collisions

abstract:
  Excitation functions of flow and stopping observables for the Au+Au system at
energies from 40 to 1500 MeV per nucleon are presented. The systematics were
obtained by merging the results of the INDRA and FOPI experiments, both
performed at the GSI facility. The connection to the nuclear equation of state
is discussed.


title: Production of Radioactive Nuclides in Inverse Reaction Kinematics

abstract:
  Efficient production of short-lived radioactive isotopes in inverse reaction
kinematics is an important technique for various applications. It is
particularly interesting when the isotope of interest is only a few nucleons
away from a stable isotope. In this article production via charge exchange and
stripping reactions in combination with a magnetic separator is explored. The
relation between the separator transmission efficiency, the production yield,
and the choice of beam energy is discussed. The results of some exploratory
experiments will be presented.


title: Recent Results on Strangeness Production at RHIC

abstract:
  Due to its large acceptance, the STAR experiment has acquired a wealth of
data on strangeness production for a variety of collisions systems and
energies, from p+p to Au+Au. By using the yields and spectra, we address the
evolution of the bulk system, including strangeness enhancement and the flavour
dependence of radial and elliptic flow. Utilising the fact that we can identify
strange baryons and mesons, we investigate different hadronization mechanisms
in the intermediate and high p$_{T}$ regions. The ratios of the particle
yields, measured to high p$_{T}$, are used to further investigate the range and
applicability of the previously reported anomalous baryon production. We also
study two-particle azimuthal correlations of identified particles in order to
investigate any flavour dependence of jet fragmentation in the available
p$_{T}$ range. Data was presented for a number of different collision systems
and energies.


title:
Target structure independent $^7\vec{Li}$ elastic scattering at low
  momentum transfers

abstract:
  Analyzing powers and cross sections for the elastic scattering of polarized
7Li by targets of 6Li, 7Li and 12C are shown to depend only on the properties
of the projectile for momentum transfers of less than 1.0 fm-1. The result of a
detailed analysis of the experimental data within the framework of the coupled
channels model with ground state reorientation and transitions to the excited
states of the projectile and targets included in the coupling schemes are
presented. This work suggests that nuclear properties of weakly-bound nuclei
can be tested by elastic scattering experiments, independent of the target
used, if data are acquired for momentum transfers less than ~1.0 fm-1.


title: Phi-meson Production in Heavy-Ion Collisions at RHIC

abstract:
  We present the first elliptic flow, $v_{2}$, measurement for the $\phi$-meson
in Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV. At low $p_{T}$ (<2 GeV/c), the
$v_{2}$ is consistent with mass ordering expected from hydrodynamics, while at
higher $p_{T}$ (>4 GeV/c), it follows the same trend as the $K^{0}_{S}$ $v_{2}$
and a parameterization for number of quarks = 2. The nuclear modification
factor, $R_{CP}$, has also been measured and it follows the same trend as the
$K^{0}_{S}$ rather than the $\Lambda$ which confirms the baryon/meson-type
dependence of $R_{CP}$ at RHIC. A model based on the recombination of thermal
s-quarks describes the central $\phi$-meson $p_{T}$ spectrum as well as the
baryon/meson ratio of $\Omega/\phi$ up to $p_{T}$ ~4 GeV/c.


title: Search for the onset of baryon anomaly at RHIC-PHENIX

abstract:
  The baryon production mechanism at the intermediate $p_T$ (2 - 5 GeV/$c$) at
RHIC is still not well understood. The beam energy scan data in Cu+Cu and Au+Au
systems at RHIC may provide us a further insight on the origin of the baryon
anomaly and its evolution as a function of $\sqrt{s_{NN}}$. In 2005 RHIC
physics program, the PHENIX experiment accumulated the first intensive low beam
energy data in Cu+Cu collisions. We present the preliminary results of
identified charged hadron spectra in Cu+Cu at $\sqrt{s_{NN}}$ = 22.5 and 62.4
GeV using the PHENIX detector. The centrality and beam energy dependences of
(anti)proton to pion ratios and the nuclear modification factors for charged
pions and (anti)protons are presented.


title: Event-by-event fluctuations and the QGP phase transition

abstract:
  Fluctuations of thermodynamic quantities are fundamental to the study of QGP
phase transition. Event-by-event fluctuations of many quantities have been
studied by dedicated heavy-ion experiments. A brief review of recent
experimental results is presented. The prospect for future study of
fluctuations is discussed.


title: Yield scalings of clusters with fewer than 100 nucleons

abstract:
  This document gives a historical review of the scaling of particles yields
emitted from excited nuclei. The focus will be on what scaling is, what can be
learned from scaling, the underlying theory of why one might expect particle
yields to scale, how experimental particle yields have been observed to scale,
model systems where particle (cluster) yields do scale and finally scaling
observed in the particle yields of various low and medium energy nuclear
reaction experiments. The document begins with a basic introduction to scaling
in the study of critical phenomena and then reviews Fisher's theory which has
all the aspects of scaling and can be directly applied to the counting of
clusters, the most reliable measurement accessible to the experimental study of
nuclear reactions. Also this document gives a history of the various scalings
observed in nuclear reaction experiments and culminates with an estimate of the
nuclear liquid-vapor phase boundary based upon measured particle yields.


title:
Shell structure at N=28 near the dripline: spectroscopy of $^{42}$Si,
  $^{43}$P and $^{44}$S

abstract:
  Measurements of the N=28 isotones 42Si, 43P and 44S using one- and two-proton
knockout reactions from the radioactive beam nuclei 44S and 46Ar are reported.
The knockout reaction cross sections for populating 42Si and 43P and a 184 keV
gamma-ray observed in 43P establish that the d_{3/2} and s_{1/2} proton orbits
are nearly degenerate in these nuclei and that there is a substantial Z=14
subshell closure separating these two orbits from the d_{5/2} orbit. The
increase in the inclusive two-proton knockout cross section from 42Si to 44S
demonstrates the importance of the availability of valence protons for
determining the cross section. New calculations of the two-proton knockout
reactions that include diffractive effects are presented. In addition, it is
proposed that a search for the d_{5/2} proton strength in 43P via a higher
statistics one-proton knockout experiment could help determine the size of the
Z=14 closure.


title: Proton-$^{3}$He elastic scattering at low energies

abstract:
  We present new accurate measurements of the differential cross section
$\sigma(\theta)$ and the proton analyzing power $A_{y}$ for proton-$^{3}$He
elastic scattering at various energies. A supersonic gas jet target has been
employed to obtain these low energy cross section measurements. The
$\sigma(\theta)$ distributions have been measured at $E_{p}$ = 0.99, 1.59,
2.24, 3.11, and 4.02 MeV. Full angular distributions of $A_{y}$ have been
measured at $E_{p}$ = 1.60, 2.25, 3.13, and 4.05 MeV. This set of
high-precision data is compared to four-body variational calculations employing
realistic nucleon-nucleon (NN) and three-nucleon (3N) interactions. For the
unpolarized cross section the agreement between the theoretical calculation and
data is good when a $3N$ potential is used. The comparison between the
calculated and measured proton analyzing powers reveals discrepancies of
approximately 50% at the maximum of each distribution. This is analogous to the
existing ``$A_{y}$ Puzzle'' known for the past 20 years in nucleon-deuteron
elastic scattering.


title: A Method for Measuring Elliptic Flow Fluctuations in PHOBOS

abstract:
  We introduce an analysis method to measure elliptic flow (v_2) fluctuations
using the PHOBOS detector for Au+Au collisions at sqrt(s) = 200 GeV. In this
method, v_2 is determined event-by-event by a maximum likelihood fit. The
non-statistical fluctuations are determined by unfolding the contribution of
statistical fluctuations and detector effects using Monte Carlo
simulations(MC). Application of this method to measure dynamical fluctuations
embedded in special MC are presented. It is shown that the input fluctuations
are reconstructed successfully for <v_2> >= 0.03.


title: New Challenges to Hydrodynamics from Azimuthal Anisotropy at RHIC

abstract:
  This paper presents $v_{4}/v_{2}^2$ ratio as a function of transverse
momentum ($p_{t}$), pseudorapidity ($\eta$) and collision centrality in Au+Au
collisions at $\sqrt{s_{NN}} = 200$ GeV using the STAR detector at the
Relativistic Heavy Ion Collider (RHIC). It is found that $v_{4}/v_{2}^2$ is
larger than Hydrodynamic calculations, the centrality and transverse dependence
of this ratio can not be fully described by Hydrodynamics, and the
pseudorapidity dependence is opposite to what one expects from Hydrodynamics.
The $p_{t}$ dependence of $v_{1}$ is also presented. It is found that
$v_{1}(p_{t})$ for $|\eta|<1.3$ changes sign, and two possible explanations of
the sign change are discussed.


title: In Beam Tests of Implanted Helium Targets

abstract:
  Targets consisting of 3,4He implanted into thin aluminum foils (approximately
100, 200 or 600 ug/cm^2) were prepared using intense (a few uA) helium beams at
low energy (approximately 20, 40 or 100 keV). Uniformity of the implantation
was achieved by a beam raster across a 12 mm diameter tantalum collimator at
the rates of 0.1 Hz in the vertical direction and 1 Hz in the horizontal
direction. Helium implantation into the very thin (approximately 80-100
ug/cm^2) aluminum foils failed to produce useful targets (with only
approximately 10% of the helium retained) due to an under estimation of the
range by the code SRIM. The range of low energy helium in aluminum predicted by
Northcliffe and Shilling and the NIST online tabulation are observed on the
other hand to over estimate the range of low energy helium ions in aluminum. An
attempt to increase the amount of helium by implanting a second deeper layer
was also carried out, but it did not significantly increase the helium content
beyond the blistering limit (approximately 6 x 10^17 helium/cm^2). The
implanted targets were bombarded with moderately intense 4He and 16O beams of
50-100 particle nA . Rutherford Back Scattering of 1.0 and 2.5 MeV proton beams
and recoil helium from 15.0 MeV oxygen beams were used to study the helium
content and profile before, during and after bombardments. We observed the
helium content and profile to be very stable even after a prolonged bombardment
(up to two days) with moderately intense beams of 16O or 4He. Helium implanted
into thin (aluminum) foils is a good choice for thin helium targets needed, for
example, for a measurement of the 3he(a,g)7Be reaction and the associated S34
astrophysical cross section factor (S-factor).


title: Heavy Flavor Production in STAR

abstract:
  In this contribution, the STAR collaboration at RHIC reports on measurements
related to heavy flavor production. We present results from D meson production,
and from indirect reconstruction of heavy flavor via semi-leptonic decays,
including low transverse momentum muons and the inclusive yield of non-photonic
electrons. We focus on the non-photonic electrons, and present results over a
broad range of transverse momenta (1.2 < pT < 10 Gev-c) in p+p, d+Au, and Au+Au
collisions at sqrt(s) = 200 GeV. The non-photonic electron yield exhibits
unexpectedly large suppression in central Au+Au collisions at high pT,
suggesting substantial heavy quark energy loss in hot QCD matter.


title:
Measurement of excited states in 40Si and evidence for weakening of the
  N=28 shell gap

abstract:
  Excited states in 40Si have been established by detecting gamma-rays
coincident with inelastic scattering and nucleon removal reactions on a liquid
hydrogen target. The low excitation energy, 986(5) keV, of the 2+[1] state
provides evidence of a weakening in the N=28 shell closure in a neutron-rich
nucleus devoid of deformation-driving proton collectivity.


title:
System Size Dependence of Azimuthal Correlations in Relativistic Heavy
  Ion Collisions

abstract:
  Systematic comparisons of jet pair correlations obtained in Cu+Cu and Au+Au
collisions at $\sqrt{s_{NN}}=$200 GeV are presented. The measured jet-pair
distributions for both systems, show strong modification of the away-side jet.
For the same number of participating nucleons, the modification does not show a
strong dependence on the collision system. It is suggested that such
comparisons can provide important constraints for models which predict specific
path length dependent jet modification effects.


title: Dielectron production in 12C+12C collisions at 2 AGeV with HADES

abstract:
  The invariant-mass spectrum of $e^+ e^-$ pairs produced in $^{12}$C+$^{12}$C
collisions at an incident energy of 2 GeV per nucleon has been measured for the
first time. The measured pair production probabilities span over five orders of
magnitude from the $\pi^0$-Dalitz to the $\rho/\omega$ invariant-mass region.
Dalitz decays of $\pi^0$ and $\eta$ account for all the yield up to 0.15
GeV/c$^2$, but for only about 50% above this mass. A comparison with model
calculations shows that the excess pair yield is likely due to baryon-resonance
and vector-meson decays. Transport calculations based on vacuum spectral
functions fail, however, to describe the entire mass region.


title: Branching ratios for the beta decay of 21Na

abstract:
  We have measured the beta-decay branching ratio for the transition from 21Na
to the first excited state of 21Ne. A recently published test of the standard
model, which was based on a measurement of the beta-nu correlation in the decay
of 21Na, depended on this branching ratio. However, until now only relatively
imprecise (and, in some cases, contradictory) values existed for it. Our new
result, 4.74(4)%, reduces but does not remove the reported discrepancy with the
standard model.


title:
Scaling properties of azimuthal anisotropy in Au+Au and Cu+Cu collisions
  at sqrt(s_NN) = 200 GeV

abstract:
  Detailed differential measurements of the elliptic flow for particles
produced in Au+Au and Cu+Cu collisions at sqrt(s_NN) = 200 GeV are presented.
Predictions from perfect fluid hydrodynamics for the scaling of the elliptic
flow coefficient v_2 with eccentricity, system size and transverse energy are
tested and validated. For transverse kinetic energies KE_T ~ m_T-m up to ~1
GeV, scaling compatible with the hydrodynamic expansion of a thermalized fluid
is observed for all produced particles. For large values of KE_T, the mesons
and baryons scale separately. A universal scaling for the flow of both mesons
and baryons is observed for the full transverse kinetic energy range of the
data when quark number scaling is employed. In both cases the scaling is more
pronounced in terms of KE_T rather than transverse momentum.


title: Acceptance effects in the hyperons global polarization measurement

abstract:
  The possible sources of systematic uncertainties in the hyperons global
polarization measurement are discussed. The equation with detector acceptance
effects taken into account is provided. Contribution of the hyperons directed
flow into the hyperons global polarization measurement is shown. The systematic
uncertainties of the Lambda hyperons global polarization measurement in Au+Au
collisions with the STAR detector at RHIC are calculated.


title: New insight into the low-energy $^9$He spectrum

abstract:
  The spectrum of $^9$He was studied by means of the $^8$He($d$,$p$)$^9$He
reaction at a lab energy of 25 MeV/n and small center of mass (c.m.) angles.
Energy and angular correlations were obtained for the $^9$He decay products by
complete kinematical reconstruction. The data do not show narrow states at
$\sim $1.3 and $\sim $2.4 MeV reported before for $^9$He. The lowest resonant
state of $^9$He is found at about 2 MeV with a width of $\sim $2 MeV and is
identified as $1/2^-$. The observed angular correlation pattern is uniquely
explained by the interference of the $1/2^-$ resonance with a virtual state
$1/2^+$ (limit on the scattering length is obtained as $a > -20$ fm), and with
the $5/2^+$ resonance at energy $\geq 4.2$ MeV.


title:
Study of the production mechanism of the eta meson by means of analysing
  power measurements

abstract:
  Information about the production mechanism of the eta meson in proton-proton
collisions can be inferred by confronting the experimental studies on the
analysing power for the p(pol)p --> pp eta reaction with the theoretical
predictions of this observable. Results show that the predictions of pure
pseudoscalar- or vector meson exchange model are insufficient to describe the
analysing powers.


title:
Evidence of large nuclear deformation of $^{32}$S$^{*}$ formed in
  $^{20}$Ne + $^{12}$C reaction

abstract:
  Deformations of hot composite $^{32}$S$^{*}$ formed in the reaction $^{20}$Ne
($\sim$ 7 -- 10 MeV/nucleon) + $^{12}$C have been estimated from the respective
inclusive $\alpha$-particle evaporation spectra. The estimated deformations for
$^{32}$S$^{*}$ have been found to be much larger than the `normal' deformations
of hot, rotating composites at similar excitations. This further confirms the
formation of highly deformed long-lived configuration of $^{20}$Ne + $^{12}$C
at high excitations ($\sim$ 70 -- 100 MeV) -- which was recently indicated from
the analysis of the complex fragment emission data for the same system.
Exclusive $\alpha$-particle evaporation spectra from the decay of hot composite
$^{32}$S$^{*}$ also show similar behaviour.


title:
Response to the comment by N. Severijns, O. Zimmer, H.-F. Wirth and D.
  Rich regarding article "Observation of the neutron radiative decay" in JETP
  Letters 83(1) p.5

abstract:
  We wouldn't like to bring up discrimination, but the tone of the commentary,
which does not contain any science-based criticism or any alternative
suggestions, does make one think of an unduly disrespectful attitude both
towards the Russian participants and the project on radiative neutron decay
itself. Here we cite our response to the commentary of our Western collaborants
to the article printed in JETP Letters 83(1) p.5. We remain firm in the
positions published in this article. In our last experiment we measured the
relative intensity of radiative neutron decay (B.R.=(3.2+-1.6) 10-3 with
C.L.=99.7% and lower energy limit of radiative gamma-quanta measured equal to
35 KeV) .


title:
Study of Dissipative Collisions of $^{20}$Ne ($\sim$7-11 MeV/nucleon) +
  $^{27}$Al

abstract:
  The inclusive energy distributions of complex fragments (3 $\leq$Z $\leq$ 9)
emitted in the reactions $^{20}$Ne (145, 158, 200, 218 MeV) + $^{27}$Al have
been measured in the angular range 10$^{o}$ - 50$^{o}$. The fusion-fission and
the deep-inelastic components of the fragment yield have been extracted using
multiple Gaussian functions from the experimental fragment energy spectra. The
elemental yields of the fusion-fission component have been found to be fairly
well exlained in the framework of standard statistical model. It is found that
there is strong competition between the fusion-fission and the deep-inelastic
processes at these energies. The time scale of the deep-inelastic process was
estimated to be typically in the range of $\sim$ 10$^{-21}$ - 10$^{-22}$ sec.,
and it was found to decrease with increasing fragment mass. The angular
momentum dissipations in fully energy damped deep-inelastic process have been
estimated from the average energies of the deep-inelastic components of the
fragment energy spectra. It has been found that, the estimated angular momentum
dissipations, for lighter fragments in particular, are more than those
predicted by the empirical sticking limit.


title: Charged Particle Production at High Rapidity in p+p Collisions at RHIC

abstract:
  This report describes the recent analysis of identified charged particle
production at high rapidity performed on data collected from p+p collisions at
RHIC (sqrt{s}=200 GeV). The extracted invariant cross-sections compare well to
NLO pQCD calculations. However, a puzzling high yield of protons at high
rapidity and p_T has been found.


title: $J/\psi$ production in PHENIX

abstract:
  Heavy quarkonia production is expected to be sensitive to the formation of a
quark gluon plasma (QGP). The PHENIX experiment has measured $J/\psi$
production at $\sqrt{s_{NN}}=$~200 GeV in Au+Au and Cu+Cu collisions, as well
as in reference p+p and d+Au runs. $J/\psi$'s were measured both at mid
($|y|<0.35$) and forward ($1.2<|y|<2.2$) rapidity. In this letter, we present
the A+A preliminary results and compare them to normal cold nuclear matter
expectations derived from PHENIX d+Au and p+p measurements as well as to
theoretical models including various effects (color screening, recombination,
sequential melting...).


title: Jet Physics at the LHC in ALICE

abstract:
  The strong suppression of high-$p_T$ hadrons observed in heavy ion collisions
at RHIC indicates the interaction of high energy partons with a dense colored
medium prior to hadronization. We review the main results from the high-$p_T$
hadron analysis at RHIC and what they tell us about the medium. We then
concentrate on the new possibilities that the wider kinematic range at the LHC
will offer and how they will help us to better characterize the medium produced
in these collisions.


title: Direct-Photon Production in Au+Au Collisions at RHIC

abstract:
  Results from the PHENIX experiment on direct-photon production in Au+Au
collisions at sqrt{s_{NN}} = 200 GeV for transverse momenta 1 < p_T < 13 GeV/c
are presented. Direct-photon yields at high p_T scale as expected for particle
production in hard processes. This supports jet-quenching models which
attribute the suppression of high-p_T hadrons to the energy loss of fast
partons in the quark-gluon plasma. The low-p_T direct-photon spectra, measured
via e+e- pairs with small invariant masses, are possibly related to the
production of thermal direct photons in Au+Au collisions at RHIC.


title: In-Medium Properties of Hadrons

abstract:
  A diverse experimental program for the study of the photoproduction of mesons
off nuclei has been carried out - and is still running - at the Mainz MAMI and
Bonn ELSA electron accelerators with the TAPS, Crystal Barrel, and Crystal Ball
calorimeters. It is motivated as a detailed study of the in-medium properties
of hadrons and the meson - nucleus interactions. Typical examples for the
in-medium behavior of vector mesons ($\omega$), scalar mesons ($\sigma$), and
nucleon resonances (P$_{33}$(1232), S$_{11}$(1535), D$_{15}$(1520)) are
discussed. Special attention is paid to meson - nucleus final state
interactions.


title:
An iterative procedure to obtain inverse response functions for
  thick-target correction of measured charged-particle spectra

abstract:
  A new method for correcting charged-particle spectra for thick target effects
is described. Starting with a trial function, inverse response functions are
found by an iterative procedure. The variances corresponding to the measured
spectrum are treated similiarly and in parallel. Oscillations of the solution
are avoided by rebinning the data to finer bins during a correction iteration
and back to the original or wider binning after each iteration. This
thick-target correction method has been used for data obtained with the MEDLEY
facility at the The Svedberg Laboratory, Uppsala, Sweden, and is here presented
in detail and demonstrated for two test cases.


title: Is there a Sonic Boom in the Little Bang at RHIC?

abstract:
  The use of elliptic flow and correlation measurements as constraints to
establish the transport properties of hot and dense QCD matter is discussed.
Measured Two- and three-particle correlation functions give initial hints for a
"sonic boom". Elliptic flow measurements give the estimates $c_s \sim 0.35$ and
$\eta/s \sim 0.1$ for the sound speed and viscosity to entropy ratio.


title:
Study of the $pd\to ^3\textrm{He} K^+K^-$ and $pd\to ^3\textrm{He} \phi$
  reactions close to threshold

abstract:
  Two--kaon production in proton--deuteron collisions has been studied at three
energies close to threshold using a calibrated magnetic spectrograph to measure
the final $^3$He and a vertex detector to measure the $K^+K^-$ pair.
Differential and total cross sections are presented for the production of
$\phi$--mesons, decaying through $\phi\to K^+K^-$, as well as for prompt
$K^+K^-$ production. The prompt production seems to follow phase space in both
its differential distributions and in its energy dependence. The amplitude for
the $pd\to ^3${He}$ \phi$ reaction varies little for excess energies below 22
MeV and the value is consistent with that obtained from a threshold
measurement. The angular distribution of the $K^+K^-$ decay pair shows that
near threshold the $\phi$--mesons are dominantly produced with polarization
$m=0$ along the initial proton direction. No conclusive evidence for $f_0(980)$
production is found in the data.


title: High Rapidity Physics with the BRAHMS Experiment

abstract:
  We report the study of the nuclear modification factor R_{AuAu} as function
of pT and pseudo-rapidity in Au+Au collisions at top RHIC energy. We find this
quantity almost independent of pseudo-rapidity. We use the pbar/pi- ratio as a
probe of the parton density and the degree of thermalization of the medium
formed by the collision. The pbar/pi- ratio has a clear rapidity dependence.
The combination of these two measurements suggests that the pseudo-rapidity
dependence of the R_{AuAu results from the competing effects of energy loss in
a dense and opaque medium and the modifications of the wave function of the
high energy beams in the initial state.


title: High-energy heavy-ions physics: from RHIC to LHC

abstract:
  A selection of experimental results in high-energy nucleus-nucleus collisions
after five years of operation of the Relativistic Heavy-Ion Collider (RHIC) is
presented. Emphasis is put on measurements that provide direct information on
fundamental properties of high-density QCD matter. The new experimental
opportunities accessible at LHC are introduced, in particular those that may
help clarify some of the current open issues at RHIC.


title: Jet Physics with Identified Particles at RHIC and LHC

abstract:
  I will present the latest results on particle identified spectra and two
particle correlations at high transverse momentum measured with the STAR
detector at RHIC. I will compare those measurements with the projected
capabilities for the LHC using the ALICE detector. The effects of string
fragmentation and quark recombination in the intermediate momentum range will
be discussed in the context of hadron formation in proton-proton and Au-Au
collisions, as well as energy loss mechanisms in the dense partonic phase. The
necessity for gamma-jet and heavy quark jet measurements will be detailed based
on the ambiguity of existing particle identified results.


title: Selected Experimental Highlights from Nucleus-Nucleus Collisions at RHIC

abstract:
  Nucleus-nucleus collisions at RHIC produce high temperature and high energy
density matter which exhibits partonic degrees of freedom. We will discuss
measurements of nuclear modification factors for light hadrons and non-photonic
electrons from heavy quark decays, which reflect the flavor dependence of
energy loss of high momentum partons traversing the dense QCD medium. The
hadronization of bulk partonic matter exhibits collectivity in effective
partonic degrees of freedom. Nuclear collisions at RHIC provide an intriguing
environment, where many constituent quark ingredients are readily available for
possible formation of exotic particles through quark coalescences or
recombinations.


title: Status of Zero Degree Calorimeter for CMS Experiment

abstract:
  The Zero Degree Calorimeter (ZDC) is integral part of the CMS experiment,
especially, for heavy ion studies. The design of the ZDC includes two
independent calorimeter sections: an electromagnetic section and a hadronic
section. Sampling calorimeters using tungsten and quartz fibers have been
chosen for the energy measurements. An overview of the ZDC is presented along
with a current status of calorimeter's preparation for Day 1 of LHC.


title:
One-neutron knockout in the vicinity of the N=32 sub-shell closure:
  9Be(57Cr,56Cr+ gamma)X

abstract:
  The one-neutron knockout reaction 9Be(57Cr,56Cr + gamma)X has been measured
in inverse kinematics with an intermediate-energy beam. Cross sections to
individual states in 56Cr were partially untangled through the detection of the
characteristic gamma-ray transitions in coincidence with the reaction residues.
The experimental inclusive longitudinal momentum distribution and the yields to
individual states are compared to calculations that combine spectroscopic
factors from the full fp shell model and nucleon-removal cross sections
computed in a few-body eikonal approach.


title: Strange prospects for LHC energies

abstract:
  Strange quark and hadron production will be studied at the Large Hadron
Collider (LHC) energies in order to explore the properties of both pp and
heavy-ion collisions. The ALICE experiment will be specifically efficient in
the strange sector with the identification of baryons and mesons over a wide
range of transverse momentum. Dedicated measurements are proposed for
investigating chemical equilibration and bulk properties. Strange particles can
also help to probe kinematical regions where hard processes and pQCD dominate.
We try to anticipate here several ALICE analyses to be performed as the first
Pb--Pb and pp data will be available.


title: Formation of 24Mg* in the Splitting of 28Si Nuclei by 1-GeV Protons

abstract:
  The 28Si(p, p' gamma)24Mg reaction has been studied at the ITEP accelerator
by the hadron-gamma coincidence method for a proton energy of 1 GeV. Two
reaction products are detected: a 1368.6-keV gamma-ray photon accompanying the
transition of the 24Mg* nucleus from the first excited state to the ground
state and a proton p' whose momentum is measured in a magnetic spectrometer.
The measured distribution in the energy lost by the proton in interaction is
attributed to five processes: the direct knockout of a nuclear alpha cluster,
the knockout of four nucleons with a total charge number of 2, the formation of
the DeltaSi isobaric nucleus, the formation of the Delta isobar in the
interaction of the incident proton with a nuclear nucleon, and the production
of a pi meson, which is at rest in the nuclear reference frame. The last
process likely corresponds to the reaction of the formation of a deeply bound
pion state in the 28P nucleus. Such states were previously observed only on
heavy nuclei. The cross sections for the listed processes have been estimated.


title:
Precision Measurements of the Nucleon Strange Form Factors at Q^2 ~0.1
  GeV^2

abstract:
  We report new measurements of the parity-violating asymmetry A_PV in elastic
scattering of 3 GeV electrons off hydrogen and 4He targets with <theta_lab>~6.0
degrees. The 4He result is A_PV = (+6.40 +/- 0.23 (stat) +/- 0.12 (syst))
x10^-6. The hydrogen result is A_PV = (-1.58 +/- 0.12 (stat) +/- 0.04 (syst))
x10^-6. These results significantly improve constraints on the electric and
magnetic strange form factors G_E^s and G_M^s. We extract G_E^s = 0.002 +/-
0.014 +/- 0.007 at <Q^2> = 0.077 GeV^2, and G_E^s + 0.09 G_M^s = 0.007 +/-
0.011 +/- 0.006 at <Q^2> = 0.109 GeV^2, providing new limits on the role of
strange quarks in the nucleon charge and magnetization distributions.


title:
Anisotropy in the pion angular distribution of the reaction pp -> pp pi0
  at 400 MeV

abstract:
  The reaction pp -> pp pi0 was studied with the WASA detector at the CELSIUS
storage ring. The center of mass angular distribution of the pi0 was obtained
by detection of the gamma decay products together with the two outgoing
protons, and found to be anisotropic with a negative second derivative slope,
in agreement with the theoretical predictions from a microscopic calculation.


title: Is soft physics entropy driven?

abstract:
  The soft physics, pT < 2 GeV/c, observables at both RHIC and the SPS have now
been mapped out in quite specific detail. From these results there is mounting
evidence that this regime is primarily driven by the multiplicity per unit
rapidity, dNch/deta. This suggests that the entropy of the system alone is the
underlying driving force for many of the global observables measured in
heavy-ion collisions. That this is the case and there is an apparent
independence on collision energy is surprising. I present the evidence for this
multiplicity scaling and use it to make some extremely naive predictions for
the soft sector results at the LHC.


title:
Dynamics Of Hadronization From Nuclear Semi Inclusive Deep Inelastic
  Scattering

abstract:
  The CLAS experiment E02-104, part of the EG2 run at Jefferson Lab, was
performed to study the hadronization process using semi inclusive deep
inelastic scattering off nuclei. Electron beam energy of 5 GeV and the CLAS
large acceptance detector were used to study charged pion production. The high
luminosity available at Jefferson Lab and the CLAS large acceptance are key
factors for such measurements allowing high statistics and therefore
multidimensional analyses of the data. Both the multiplicity ratio and the
transverse momentum broadening for carbon, iron and lead relative to deuterium
are measured. Preliminary results for positive pions are discussed.


title: Wounded Nucleons, Wounded Quarks, and Relativistic Ion Collisions

abstract:
  A concept of wounded nucleons and/or wounded quarks plays an important role
in parametrizing and to some extent explaining many a feature of the
relativistic ion collisions. This will be illustrated in a historical
perspective, up to and including the latest developpments.


title:
Measurement of the proton electric to magnetic form factor ratio from
  \vec ^1H(\vec e, e'p)

abstract:
  We report the first precision measurement of the proton electric to magnetic
form factor ratio from spin-dependent elastic scattering of longitudinally
polarized electrons from a polarized hydrogen internal gas target. The
measurement was performed at the MIT-Bates South Hall Ring over a range of
four-momentum transfer squared $Q^2$ from 0.15 to 0.65 (GeV/c)$^2$.
Significantly improved results on the proton electric and magnetic form factors
are obtained in combination with previous cross-section data on elastic
electron-proton scattering in the same $Q^2$ region.


title:
Multi-layer scintillation detector for the MOON double beta decay
  experiment: Scintillation photon responses studied by a prototype detector
  MOON-1

abstract:
  An ensemble of multi-layer scintillators is discussed as an option of the
high-sensitivity detector Mo Observatory Of Neutrinos (MOON) for spectroscopic
measurements of neutrino-less double beta decays. A prototype detector MOON-1,
which consists of 6 layer plastic-scintillator plates, was built to study the
sensitivity of the MOON-type detector. The scintillation photon collection and
the energy resolution, which are key elements for the high-sensitivity
experiments, are found to be 1835+/-30 photo-electrons for 976 keV electrons
and sigma = 2.9+/-0.1% (dE/E = 6.8+/-0.3 % in FWHM) at the Qbb ~ 3 MeV region,
respectively. The multi-layer plastic-scintillator structure with good energy
resolution as well as good background suppression of beta-gamma rays is crucial
for the MOON-type detector to achieve the inverted hierarchy neutrino mass
sensitivity.


title: Ways to constrain the away side jet in Au + Au collisions in PHENIX

abstract:
  We discussed methods used by the PHENIX to constrain the flow background in
the two particle jet correlation. Both the background level and elliptic flow
can be reliably decomposed from the jet contribution. We also studied the
non-flow contribution to the reaction plane elliptic flow due to dijets. We
found the jet bias is negligible in PHENIX, when the reaction plane is measured
at Beam Beam Counter acceptance ($3<|\eta|<4$).
