Verification of the content, isotopic composition and age of plutonium
  in Pu-Be neutron sources by gamma-spectrometry

abstract:
  A non-destructive, gamma-spectrometric method for verifying the plutonium
content of Pu-Be neutron sources has been developed. It is also shown that the
isotopic composition and the age of plutonium (Pu) can be determined in the
intensive neutron field of these sources by the ``Multi-Group Analysis''
method. Gamma spectra were taken in the far-field of the sample, which was
assumed to be cylindrical. The isotopic composition and the age of Pu were
determined using a commercial implementation of the Multi-Group Analysis
algorithm. The Pu content of the sources was evaluated from the count rates of
the gamma-peaks of 239Pu, relying on the assumption that the gamma-rays are
coming to the detector parallel to each other. The determination of the
specific neutron yields and the problem of neutron damage to the detector are
also discussed.


title: Probing Dense Partonic Matter at RHIC

abstract:
  Recent Results from the PHENIX Collaboration on Au+Au and d+Au collisions at
the Relativistic Heavy Ion Collider.


title: Photoabsorption and Photoproduction on Nuclei in the Resonance Region

abstract:
  Inclusive studies of nuclear photoabsorption have provided clear evidence of
medium modifications in the properties of hadrons. However, the results have
not been explained in a model independent way. A deeper understanding of the
situation is expected from a detailed comparison of meson photoproduction from
nucleons and from nuclei in exclusive reactions. Recent experimental results
are presented.


title: High energy Cherenkov gluons at RHIC and LHC

abstract:
  The collective effect of emission by the forward moving partons of high
energy Cherenkov gluons in nucleus-nucleus collisions at RHIC and LHC energies
is considered. It can reveal itself as peaks in the pseudorapidity distribution
of jets at midrapidities or as a ring-like structure of individual events in
event-by-event analysis. The pseudorapidity distribution of centers of dense
isolated groups of particles in HIJING model is determined. It can be
considered as the background for Cherenkov gluons. If peaks above this
background were found in experiment, they would indicate new collective
effects.


title:
Nuclear mass form factors from coherent photoproduction of $\pi^0$
  mesons

abstract:
  Data for coherent photoproduction of $\pi^0$ mesons from nuclei ($^{12}$C,
$^{40}$Ca, $^{93}$Nb, $^{nat}$Pb), recently measured with the TAPS detector at
the Mainz MAMI accelerator, have been analyzed in view of the mass form factors
of the nuclei. The form factors have been extracted in plane wave approximation
of the $A(\gamma ,\pi^0)A$ reaction and corrected for final state interaction
effects with the help of distorted wave impulse approximations. Nuclear mass
rms-radii have been calculated from the slope of the form factors for $q^2\to
0$. Furthermore, the Helm model (hard sphere form factor folded with Gaussian)
was used to extract diffraction radii from the zeroes of the form factor and
skin thicknesses from the position and height of its first maximum. The
diffraction radii from the Helm model agree with the corresponding charge radii
obtained from electron scattering experiments within their uncertainties of a
few per cent. The rms-radii from the slope of the form factors are
systematically lower by up to 5% for PWIA and up to 10% for DWIA. Also the skin
thicknesses extracted from the Helm model are systematically smaller than their
charge counter parts.

Recoil Polarization Measurements for Neutral Pion Electroproduction at
  Q^2=1 (GeV/c)^2 Near the Delta Resonance

abstract:
  We measured angular distributions of differential cross section, beam
analyzing power, and recoil polarization for neutral pion electroproduction at
Q^2 = 1.0 (GeV/c)^2 in 10 bins of W across the Delta resonance. A total of 16
independent response functions were extracted, of which 12 were observed for
the first time. Comparisons with recent model calculations show that response
functions governed by real parts of interference products are determined
relatively well near 1.232 GeV, but variations among models is large for
response functions governed by imaginary parts and for both increases rapidly
with W. We performed a nearly model-independent multipole analysis that adjusts
complex multipoles with high partial waves constrained by baseline models.
Parabolic fits to the W dependence of the multipole analysis around the Delta
mass gives values for SMR = (-6.61 +/- 0.18)% and EMR = (-2.87 +/- 0.19)% that
are distinctly larger than those from Legendre analysis of the same data.
Similarly, the multipole analysis gives Re(S0+/M1+) = (+7.1 +/- 0.8)% at
W=1.232 GeV, consistent with recent models, while the traditional Legendre
analysis gives the opposite sign because its truncation errors are quite
severe. Finally, using a unitary isobar model (UIM), we find that excitation of
the Roper resonance is dominantly longitudinal with S1/2 = (0.05 +/- 0.01)
GeV^(-1/2) at Q^2=1. The ReS0+ and ReE0+ multipoles favor pseudovector coupling
over pseudoscalar coupling or a recently proposed mixed-coupling scheme, but
the UIM does not reproduce the imaginary parts of 0+ multipoles well.


title: S-factor of 14N(p,gamma)15O at astrophysical energies

abstract:
  The astrophysical S-factor of 14N(p,gamma)15O has been measured for effective
center-of-mass energies between E_eff = 119 and 367 keV at the LUNA facility
using TiN solid targets and Ge detectors. The data are in good agreement with
previous and recent work at overlapping energies. R-matrix analysis reveals
that due to the complex level structure of 15O the extrapolated S(0) value is
model dependent and calls for additional experimental efforts to reduce the
present uncertainty in S(0) to a level of a few percent as required by
astrophysical calculations.

The 40Ca(alpha,gamma)44Ti reaction in the energy regime of supernova
  nucleosynthesis

abstract:
  The 44Ti(t1/2 = 59 y) nuclide, an important signature of supernova
nucleosynthesis, has recently been observed as live radioactivity by gamma-ray
astronomy from the Cas A remnant. We investigate in the laboratory the major
44Ti production reaction, 40Ca(alpha,gamma)44Ti (E_cm = 0.6-1.2 MeV/u), by
direct off- line counting of 44Ti nuclei. The yield, significantly higher than
inferred from previous experiments, is analyzed in terms of a statistical model
using microscopic nuclear inputs. The associated stellar rate has important
astrophysical consequences, increasing the calculated supernova 44Ti yield by a
factor ~2 over previous estimates and bringing it closer to Cas A observations.


title: Sum Rules and Moments of the Nucleon Spin Structure Functions

abstract:
  The nucleon has been used as a laboratory to investigate its own spin
structure and Quantum Chromodynamics. New experimental data on nucleon spin
structure at low to intermediate momentum transfers combined with existing high
momentum transfer data offer a comprehensive picture of the transition region
from the {\it confinement} regime of the theory to its {\it asymptotic freedom}
regime. Insight for some aspects of the theory is gained by exploring lower
moments of spin structure functions and their corresponding sum rules (i.e. the
Gerasimov-Drell-Hearn, Bjorken and Burkhardt-Cottingham). These moments are
expressed in terms of an operator product expansion using quark and gluon
degrees of freedom at moderately large momentum transfers. The sum rules are
verified to a good accuracy assuming that no singular behavior of the structure
functions is present at very high excitation energies. The higher twist
contributions have been examined through the moments evolution as the moments
evolution as the momentum transfer varies from higher to lower values.
Furthermore, QCD-inspired low-energy effective theories, which explicitly
include chiral symmetry breaking, are tested at low momentum transfers. The
validity of these theories is further examined as the momentum transfer
increases to moderate values. It is found that chiral perturbation calculations
agree reasonably well with the first moment of the spin structure function
$g_1$ at momentum transfer of 0.1 GeV$^2$ but fail to reproduce the neutron
data in the case of the generalized polarizability $\delta_{LT}$.

Vector and Tensor Analyzing Powers of the H(d,gamma)He-3 capture
  reaction

abstract:
  Precise measurements of the deuteron vector analyzing power Ayd and the
tensor analyzing power Ayy of the H(d,gamma)He-3 capture reaction have been
performed at deuteron energies of 29MeV and 45MeV. The data have been compared
to theoretical state-of-the-art calculations available today. Due to the large
sensitivity of polarization observables and the precision of the data light
could be shed on small effects present in the dynamics of the reaction.


title:
Rapidity distributions around mid-rapidity of strange particles in Pb-Pb
  collisions at 158 $A$ GeV/c

abstract:
  The production at central rapidity of K0s, Lambda, Xi and Omega particles in
Pb-Pb collisions at 158 A GeV/c has been measured by the NA57 experiment over a
centrality range corresponding to the most central 53% of the inelastic Pb-Pb
cross section. In this paper we present the rapidity distribution of each
particle in the central rapidity unit as a function of the event centrality.
The distributions are analyzed based on hydrodynamical models of the
collisions.


title: Estimate of average freeze-out volume in multifragmentation events

abstract:
  An estimate of the average freeze-out volume for multifragmentation events is
presented. Values of volumes are obtained by means of a simulation using the
experimental charged product partitions measured by the 4pi multidetector INDRA
for 129Xe central collisions on Sn at 32 AMeV incident energy. The input
parameters of the simulation are tuned by means of the comparison between the
experimental and simulated velocity (or energy) spectra of particles and
fragments.


title:
Single Electron Transverse Momentum and Azimuthal Anisotropy
  Distributions: Charm Hadron Production at RHIC

abstract:
  Quantum Chromodynamics (QCD) is a basic gauge field theory to describe strong
interactions. Lattice QCD calculations predict a phase transition from hadronic
matter to a deconfined, locally thermalized Quark-Gluon Plasma (QGP) state at
high temperature and small baryon density. Plenty of exciting results from RHIC
experiments in the first three years have demonstrated that a hot dense matter
with strong collective motion which cannot be described with hadronic degrees
of freedom was created at RHIC. Charm quarks are believed to be mostly created
from initial gluon fusion in heavy ion collisions. Since they are massive,
charm hadrons are proposed to be ideal probes to study the early stage dynamics
in heavy ion collisions.
  We provide here an indirect measurement of charm semi-leptonic decay. Single
electron transverse momentum ($p_T$) distributions from 200 GeV \dAu, \pp
collisions and 62.4 GeV \AuAu collisions, and single electron azimuthal
anisotropy ($v_2$) from 62.4 GeV \AuAu collisions are presented. (Abridged)


title: The pion parton distribution function in the valence region

abstract:
  The parton distribution function of the pion in the valence region is
extracted in a next-to-leading order analysis from Fermilab E-615 pionic
Drell-Yan data. The effects of the parameterization of the pion's valence
distributions are examined. Modern nucleon parton distributions and nuclear
corrections were used and possible effects from higher twist contributions were
considered in the analysis. In the next-to-leading order analysis, the high-$x$
dependence of the pion structure function differs from that of the leading
order analysis, but not enough to agree with the expectations of pQCD and
Dyson-Schwinger calculations.


title: Dual Magnetic Separator for TRI$\mu$P

abstract:
  The TRI$\mu$P facility, under construction at KVI, requires the production
and separation of short-lived and rare isotopes. Direct reactions,
fragmentation and fusion-evaporation reactions in normal and inverse kinematics
are foreseen to produce nuclides of interest with a variety of heavy-ion beams
from the superconducting cyclotron AGOR. For this purpose, we have designed,
constructed and commissioned a versatile magnetic separator that allows
efficient injection into an ion catcher, i.e., gas-filled stopper/cooler or
thermal ionizer, from which a low energy radioactive beam will be extracted.
The separator performance was tested with the production and clean separation
of $^{21}$Na ions, where a beam purity of 99.5% could be achieved. For
fusion-evaporation products, some of the features of its operation as a
gas-filled recoil separator were tested.


title:
The reaction 13C(alpha,n)16O: a background for the observation of
  geo-neutrinos

abstract:
  The absolute cross section of the $^{13}$C($\alpha$,n)$^{16}$O reaction has
been measured at E$_{\alpha}$ = 0.8 to 8.0 MeV with an overall accuracy of 4%.
The precision is needed to subtract reliably a background in the observation of
geo-neutrinos, e.g. in the KamLAND detector.


title:
Exclusive Measurement of the Nonmesonic Weak Decay of ^{5}_{\Lambda}He
  Hypernucleus

abstract:
  We performed a coincidence measurement of two nucleons emitted from the
nonmesonic weak decay (NMWD) of ^{5}_{\Lambda}He formed via the
^{6}Li(\pi^+,K^+) reaction. The energies of two nucleons and the pair number
distributions in the opening angle between them were measured. In both np and
nn pairs, we observed a clean back-to-back correlation coming from the two-body
decay of \Lambda p --> n p and \Lambda n --> n n, respectively. The ratio of
the nucleon pair numbers was N_{nn}/N_{np}=0.45 \pm 0.11(stat)\pm 0.03(syst) in
the kinematic region of cos(theta_{NN}) < -0.8. Since each decay mode was
exclusively detected, the measured ratio should be close to the ratio of
\Gamma(\Lambda p --> np)/\Gamma(\Lambda n --> nn).
  The ratio is consistent with recent theoretical calculations based on the
heavy meson/direct quark exchange picture.


title:
Exclusive proton asymmetry measurement in non-mesonic weak decay of
  polarized 5_Lambda_He

abstract:
  The asymmetry parameter alpha_p^NM for a proton exclusively emitted in the
Lambda p -> np process was, for the first time, measured in the non-mesonic
weak decay of a polarized 5_La,bda_He hypernucleus by selecting the
proton-neutron pairs emitted in the back-to-back kinematics. The highly
polarized 5_Lambda_He was abundantly produced with the (pi+,K+) reaction at
1.05GeV/c in the scattering angular range of +-15$ degrees. The obtained value
alpha_p^NM=0.31+-0.22, as well as that for inclusive protons,
alpha_p^NM=0.11+-0.08+-0.04, largely contradicts recent theoretical values of
around -0.6, although these calculations well reproduce the branching ratios of
non-mesonic weak decay.


title:
Simultaneous measurement of the photodisintegration of 4He in the giant
  dipole resonance region

abstract:
  We have performed for the first time the simultaneous measurement of the
two-body and three-body photodisintegration cross-sections of 4He in the energy
range from 21.8 to 29.8 MeV using monoenergetic pulsed photons and a 4-pi time
projection chamber containing 4He gas as an active target in an event-by-event
mode. The photon beam was produced via the Compton backscattering of laser
photons with high-energy electrons. The 4He(gamma,p)3H and 4He(gamma,n)3He
cross sections were found to increase monotonically with energy up to 29.8 MeV,
in contrast to the result of a recent theoretical calculation based on the
Lorentz integral transform method which predicted a pronounced peak at around
26-27 MeV. The energy dependence of the obtained 4He(gamma,n)3He cross section
up to 26.5 MeV is marginally consistent with a Faddeev-type calculation
predicting a flat pattern of the excitation function. The cross-section ratio
of 4He(gamma,p)3H to 4He(gamma,n)3He is found to be consistent with the
expected value for charge symmetry of the strong interaction within the
experimental uncertainty in the measured energy range. The present results for
the total and two-body cross-sections of the photodisintegration of 4He are
compared to previous experimental data and recent theoretical calculations.


title:
Measuring the Neutron's Mean Square Charge Radius Using Neutron
  Interferometry

abstract:
  The neutron is electrically neutral, but its substructure consists of charged
quarks so it may have an internal charge distribution. In fact it is known to
have a negative mean square charge radius (MSCR), the second moment of the
radial charge density. In other words the neutron has a positive core and
negative skin. In the first Born approximation the neutron MSCR can be simply
related to the neutron-electron scattering length b_ne. In the past this
important quantity has been extracted from the energy dependence of the total
transmission cross-section of neutrons on high-Z targets, a very difficult and
complicated process. A few years ago S.A. Werner proposed a novel approach to
measuring b_ne from the neutron's dynamical phase shift in a perfect crystal
close to the Bragg condition. We are conducting an experiment based on this
method at the NIST neutron interferometer which may lead to a five-fold
improvement in precision of b_ne and hence the neutron MSCR.

New Mass and Lifetime Measurements of $^{152}$Sm Projectile Fragments
  with Time-Resolved Schottky Mass Spectrometry

abstract:
  The FRS-ESR facilities at GSI provide unique conditions for precision
measurements with stored exotic nuclei over a large range in the chart of
nuclides. In the present experiment the exotic nuclei were produced via
fragmentation of $^{152}$Sm projectiles in a thick beryllium target at 500-600
MeV/u, separated in-flight with the fragment separator FRS, and injected into
the storage-cooler ring ESR. Mass and lifetime measurements have been performed
with bare and few-electron ions. The experiment and first results will be
presented in this contribution.

Beta decay of 115-In to the first excited level of 115-Sn: Potential
  outcome for neutrino mass

abstract:
  Recent observation of beta decay of 115-In to the first excited level of
115-Sn with an extremely low Q_beta value (Q_beta ~ 1 keV) could be used to set
a limit on neutrino mass. To give restriction potentially competitive with
those extracted from experiments with 3-H (~2 eV) and 187-Re (~15 eV), atomic
mass difference between 115-In and 115-Sn and energy of the first 115-Sn level
should be remeasured with higher accuracy (possibly of the order of ~1 eV).

Change of 7Be decay rate in exohedral and endohedral C60 fullerene
  compounds and its implications

abstract:
  The half-life of 7Be implanted in a C60 pellet and gold foil has been
measured to be about the same within about 0.2%. Using a radiochemical
technique, we also measured that the probability of formation of endohedral
7Be@C60 by nuclear implantation technique was (5.6+-0.45)%. It is known from
earlier works that the half-life of endohedral 7Be@C60 is about 1.2% shorter
than that of 7Be implanted in gold. An analysis of these results using linear
muffin-tin orbital method calculations indicates that most of the implanted 7Be
ions in fullerene C60 stay at a distance of about 5.3 Angstrom from the centers
of nearest C60 molecules forming exohedral compounds and those who enter the
fullerene cages go to the centers of the cages forming endohedral 7Be@C60
compounds.


title:
Photoproduction of $\eta$-mesons off C and Cu nuclei for photon energies
  below 1.1 GeV

abstract:
  The $\eta$-meson photoproduction cross sections have been measured on the C
and Cu targets for the photon energies between 600 and 1100 MeV to investigate
the behavior of the $S_{11}$(1535) resonance in a nucleus. The excitation
functions of the cross section as well as the angular and momentum
distributions of $\eta$-mesons are in quantitative agreement with the Quantum
Molecular Dynamics (QMD) model calculations in which the $\eta$-meson emission
processes other than the $S_{11}$(1535) resonance are also incorporated as
proposed in the $\eta$-MAID model. It is shown that the excitation of the
$D_{15}$(1675) resonance might play an important role for $E_{\gamma}>900$ MeV.


title: Heavy Quarks and Heavy Quarkonia as Tests of Thermalization

abstract:
  We present here a brief summary of new results on heavy quarks and heavy
quarkonia from the PHENIX experiment as presented at the "Quark Gluon Plasma
Thermalization" Workshop in Vienna, Austria in August 2005, directly following
the International Quark Matter Conference in Hungary.


title:
Ortho-para transition rate in $\mu$-molecular hydrogen and the proton's
  induced pseudoscalar coupling $g_p$

abstract:
  We report a measurement of the ortho-para transition rate in the p$\mu$p
molecule. The experiment was conducted at TRIUMF via the measurement of the
time dependence of the 5.2 MeV neutrons from muon capture in liquid hydrogen.
The measurement yielded an ortho-para rate $\Lambda_{op} = (11.1 \pm 1.7
\pm^{0.9}_{0.6}) \times 10^4$ s$^{-1}$ that is substantially larger than the
earlier result of Bardin {\it et al.} We discuss the striking implications for
the proton's induced pseudoscalar coupling $g_p$.


title:
Pulse shape analysis in segmented detectors as a technique for
  background reduction in Ge double-beta decay experiments

abstract:
  The need to understand and reject backgrounds in Ge-diode detector
double-beta decay experiments has given rise to the development of pulse shape
analysis in such detectors to discern single-site energy deposits from
multiple-site deposits. Here, we extend this analysis to segmented Ge detectors
to study the effectiveness of combining segmentation with pulse shape analysis
to identify the multiplicity of the energy deposits.


title: Analysis of Dynamic Multiplicity Fluctuations at PHOBOS

abstract:
  This paper presents the analysis of the dynamic fluctuations in the inclusive
charged particle multiplicity measured by PHOBOS for Au+Au collisions at
sqrt(s_NN)=200$GeV within the pseudo-rapidity range of -3<eta<3. First the
definition of the fluctuations observables used in this analysis is presented,
together with the discussion of their physics meaning. Then the procedure for
the extraction of dynamic fluctuations is described. Some preliminary results
are included to illustrate the correlation features of the fluctuation
observable. New dynamic fluctuations results will be available in a later
publication.


title:
Implications of two-body fragment decay for the interpretation of
  emission chronology from velocity-gated correlation functions

abstract:
  From velocity-gated small-angle correlation functions the emission chronology
can be deduced for non-identical particles, if the emission is independent.
This is not the case for non-identical particles that originate from two-body
decay of fragments. Experimental results may contain contributions from both
independent emission and two-body decay, so care is needed in interpreting the
velocity-gated correlation functions. It is shown that in some special cases,
it is still possible to deduce the emission chronology, even if there is a
contribution from two-body decay.

Produzione di particelle strane in interazioni piombo-piombo e
  protone-piombo a 160 GeV/c per nucleone

abstract:
  This PhD thesis is about the production of strange particles in heavy-ion
collisions at high energy produced at the SPS CERN syncrotron. Results are from
experiment WA85 and WA97. They have been compared with VENUS and RQMD
simulations. An increase in strangeness production has been observed which
cannot be explained in terms of superposition of hadron-hadron collisions. It
is in favour of a QGP scenario, developed in the early stages of the collisions


title:
Transverse-momentum $p_t$ correlations on $(\eta,\phi)$ from
  mean-$p_{t}$ fluctuations in Au-Au collisions at $\sqrt{s_{NN}} = $ 200 GeV

abstract:
  We present first measurements of the pseudorapidity and azimuth $(\eta,\phi)$
bin-size dependence of event-wise mean transverse momentum $<p_{t} >$
fluctuations for Au-Au collisions at $\sqrt{s_{NN}} = 200$ GeV. We invert that
dependence to obtain $p_t$ autocorrelations on differences
$(\eta_\Delta,\phi_\Delta)$ interpreted to represent velocity/temperature
distributions on ($\eta,\phi$). The general form of the autocorrelations
suggests that the basic correlation mechanism is parton fragmentation. The
autocorrelations vary strongly with collision centrality, which suggests that
fragmentation is strongly modified by a dissipative medium in the more central
Au-Au collisions relative to peripheral or p-p collisions. \\


title:
The BNO-LNGS joint measurement of the solar neutrino capture rate in
  71Ga

abstract:
  We describe a cooperative measurement of the capture rate of solar neutrinos
by the reaction 71Ga(\nu_e,e^-)71Ge. Extractions were made from a portion of
the gallium target in the Russian-American Gallium Experiment SAGE and the
extraction samples were transported to the Gran Sasso laboratory for synthesis
and counting at the Gallium Neutrino Observatory GNO. Six extractions of this
type were made and the resultant solar neutrino capture rate was 64
^{+24}_{-22} SNU, which agrees well with the overall result of the gallium
experiments. The major purpose of this experiment was to make it possible for
SAGE to continue their regular schedule of monthly solar neutrino extractions
without interruption while a separate experiment was underway to measure the
response of 71Ga to neutrinos from an 37Ar source. As side benefits, this
experiment proved the feasibility of long-distance sample transport in ultralow
background radiochemical experiments and familiarized each group with the
methods and techniques of the other.


title: New results on SIDIS SSA from Jefferson Lab

abstract:
  We present studies of single-spin and double-spin asymmetries in
semi-inclusive electroproduction of pions using the CEBAF 6 GeV polarized
electron beam. Kinematic dependences of single and double spin asymmetries have
been measured in a wide kinematic range at CLAS with a polarized NH$_3$ target.
Significant target-spin $\sin2\phi$ and $\sin\phi$ asymmetries have been
observed. The hypothesis of factorization has been tested with $z$-dependence
of the double spin asymmetry.


title:
Differential Cross Sections for gamma + p --> K+ + Y for Lambda and
  Sigma0 Hyperons

abstract:
  High-statistics cross sections for the reactions gamma + p --> K^+ + Lambda
and gamma + p --> K^+ + Sigma^0 have been measured using CLAS at Jefferson Lab
for center-of-mass energies W between 1.6 and 2.53 GeV, and for -0.85 < cos
theta_{K^+}^{c.m.}< +0.95. In the K^+ Lambda channel we confirm a
resonance-like structure near W=1.9 GeV at backward kaon angles. The position
and width of this structure change with angle, indicating that more than one
resonance is likely playing a role. The K^+ Lambda channel at forward angles
and all energies is well described by a t-channel scaling characteristic of
Regge exchange, while the same scaling applied to the K^+ Sigma^0 channel is
less successful. Several existing theoretical models are compared to the data,
but none provide a good representation of the results.


title:
Charged-Particle Pseudorapidity Distributions in Au+Au Collisions at
  sqrt(s_NN)=62.4 GeV

abstract:
  The charged-particle pseudorapidity density for Au+Au collisions at
sqrt(s_NN)=62.4 GeV has been measured over a wide range of impact parameters
and compared to results obtained at other energies. As a function of collision
energy, the pseudorapidity distribution grows systematically both in height and
width. The mid-rapidity density is found to grow approximately logarithmically
between AGS energies and the top RHIC energy. As a function of centrality,
there is an approximate factorization of the centrality dependence of the
mid-rapidity yields and the overall multiplicity scale. The new results at
sqrt(s_NN)=62.4 GeV confirm the previously observed phenomenon of ``extended
longitudinal scaling'' in the pseudorapidity distributions when viewed in the
rest frame of one of the colliding nuclei. It is also found that the evolution
of the shape of the distribution with centrality is energy independent, when
viewed in this reference frame. As a function of centrality, the total charged
particle multiplicity scales linearly with the number of participant pairs as
it was observed at other energies.


title:
Energy dependence of transverse mass spectra of Lambda hyperons produced
  in p+p and p+pbar interactions. A compilation

abstract:
  The results on transverse mass spectra of Lambda hyperons produced in all
inelastic p+p and p+pbar interactions in the energy range sqrts = 3.6-1800 GeV
are compiled and analyzed. The energy dependence of the mean transverse mass
and the inverse slope parameter of the spectra is presented and discussed.
These results should be used as a reference in the study of Lambda hyperon
production in nuclear collisions.


title: System and Energy Dependence of Strangeness Production with STAR

abstract:
  The yields and spectra of strange hadrons have each been measured by STAR as
a function of centrality in $\rm \sqrt{s_{NN}}=$ 200 GeV AuAu collisions. By
comparison to measurements in pp and dAu at $\rm \sqrt{s_{NN}}=200$ GeV and in
AuAu at $\rm \sqrt{s_{NN}}=62$ GeV the dependence on system size and energy is
studied. Short-lived resonances, such as $\Sigma (1385)$ and $\Lambda (1520)$,
that may decay and regenerate in the medium, are used to examine the dynamical
evolution between production and freeze-out for these systems. Particle
production is investigated by comparison to thermal models, which assume a
simple scaling of the yield with $\rm N_{part}$, in order to calculate the
strangeness enhancement. Our hyperon measurements in AuAu indicate that $\rm
N_{bin}$ may be a more appropriate scale for the strangeness correlation
volume. In this case canonical suppression can not be simply parameterized with
the geometrical overlap volume but will depend on the individual quark content
of each particle. This theory is tested by comparing the data from different
collision systems and centralities.


title: Recent Results on Searches for Pentaquark States from STAR at RHIC

abstract:
  We present results on pentaquark searches from nuclear collisions at RHIC
with the STAR detector system. An intriguing peak has been observed in the
invariant mass distribution of $pK^{+}+\overline{p}K^{-}$ from 18.6 Million
d+Au collision events at $\sqrt{s_{_{NN}}} = 200$~GeV. The peak centers at a
mass $1528 \pm 2 \pm 5$~MeV/c$^{2}$ and the FWHM $\sim15$ MeV/c$^{2}$ limited
by detector responses. The statistical significance of the peak is $4.2\sigma$.
Such a state if confirmed is manifestly exotic and implies a family of isospin
one states. A weak signal of less statistical significance ($\sim3\sigma$) has
been observed in 5.6M Au+Au collision events at 62.4 GeV. Searches in 10.7M
Au+Au collision events at 200 GeV yield no significant signal. The Au+Au
results neither confirm nor rule out the d+Au observation as a possible state.


title: Open Charm Production at RHIC

abstract:
  Recent experimental measurements on open charm production in proton-proton,
proton (deuteron)-nucleus and nucleus-nucleus collisions at RHIC are reviewed.
A comparison with theoretical predictions is made. Some unsettled issues in
open charm production call for precise measurements on directly reconstructed
open charm hadrons.


title: First Results from Photon Multiplicity Detector at RHIC

abstract:
  We present the first measurement of multiplicity and pseudorapidity
distributions of photons in the pseudorapidity region 2.3 < eta < 3.7 for
different centralities in Au + Au collisions at sqrt{s_NN} = 62.4 GeV. The
pseudorapidity distribution of photons, dominated by neutral pion decays, has
been compared to those of identified charged pions, photons, and inclusive
charged particles from heavy ion and nucleon-nucleon collisions at various
energies. Scaling of photon yield with number of participating nucleons and
limiting fragmentation scenario for inclusive photon production has been
studied.

Particle production at forward rapidity in d+Au and Au+Au collisions in
  STAR experiment at RHIC

  We present the recent results from the STAR experiment on charged and neutral
particle measurements at the forward rapidity in d+Au collisions at
sqrt{s_{NN}} = 200 GeV and Au+Au collisions at sqrt{s_{NN}} = 62.4 GeV. The
nuclear modification factor for charged and neutral hadrons in d+Au collisions
are presented. Measurements of Lambda and anti-Lambda production at forward
rapidity and the variation of net baryon density as a function of collision
centrality are discussed. We have also studied the limiting fragmentation of
photons and charged particles in Au+Au collisions. The photons and charged
particles separately follow the energy independent limiting fragmentation
behaviour. However they have been observed to follow a different centrality
dependence of limiting fragmentation.

NA49 results on hadron production: indications of the onset of
  deconfinement ?

abstract:
  The NA49 experiment at the CERN SPS measured the energy and system size
dependence of particle production in A+A collisions. A change of the energy
dependence of several hadron production properties at low SPS energies is
observed which suggests a scenario requiring the onset of deconfinement.


title: Measurement and analysis of two- and three-particle correlations

abstract:
  Allowed regions of core fraction versus partial coherence are obtained from
analysis of both two- and three-pion Bose-Einstein correlations measured at
PHENIX in $\sqrt{s_{NN}}=200$ GeV Au+Au collisions. Two-pion Bose-Einstein
correlation functions for different average transverse momenta are used to
analyze chiral symmetry restoration.


title: Results from NA57

abstract:
  The NA57 experiment has measured the production of strange and multi-strange
hadrons in heavy-ion collisions at the CERN SPS. After briefly introducing the
NA57 apparatus and analysis procedures, we present recent results on
strangeness enhancement in Pb-Pb relative to p-Be collisions, on the study of
the m_T distributions of strange particles, and on central-to-peripheral
nuclear modification factors in Pb-Pb collisions at top SPS energy.


title: Direct observation of dijets in central Au+Au collisions with STAR

abstract:
  We present first results of azimuthal (Delta phi) correlations of high
transverse momentum (p_T) hadrons from the high-statistics Au+Au dataset
collected at RHIC in 2004. Previous correlations measurements observed the
disappearance of back-to-back (Delta phi ~ pi) correlations in central Au+Au
collisions, supporting the emerging picture of parton energy loss in dense QCD
matter. In the present analysis, increasing the p_T thresholds reveals a narrow
back-to-back dijet peak which emerges above the decreasing combinatoric
background. We study the possible medium modification of the dijet
fragmentation function and compare to models, to place constraints on the
nature and magnitude of in-medium energy loss.


title: A Heavy-Flavor Tracker for STAR

abstract:
  We propose to construct a heavy flavor tracker for the STAR experiment at
RHIC in order to measure the elliptic flow of charmed hadrons in the low pt
region and identify B-meson contributions in the region pt > 4 GeV/c. In this
talk, we will present the design of the detector in-depth and its expected
performance as studied in detailed simulations and analytic calculations.
Physics potentials of the detector will also be discussed.


title: Heavy-Flavor Collectivity - Light-Flavor Thermalization at RHIC

abstract:
  Flow measurements of multi-strange baryons from Au + Au collisions at RHIC
energies demonstrate that collectivity develops before hadronization, among
partons. To pin down the partonic EOS of matter produced at RHIC, the status of
thermalization in such collisions has to be addressed. We propose to measure
collective flow of heavy-flavor quarks, e.g. charm quarks, as an indicator of
thermalization of light flavors ($u,d,s$). The completion of the time of flight
barrel and the proposed upgrade with a $\mu$Vertex detector for heavy-flavor
identification in STAR are well suited for achieving these goals.


title:
Resolving the Discrepancy of 135 MeV pd Elastic Scattering Cross
  Sections and Relativistic Effects

abstract:
  Three precise measurements for elastic pd scattering at 135 MeV/A have been
performed with the three different experimental setups. The cross sections are
described well by the theoretical predictions based on modern nucleon-nucleon
forces combined with three nucleon forces. Relativistic Faddeev calculations
show that relativistic effects are restricted to backward angles. This result
supports the two measurements recently reported by RIKEN and contradicts the
KVI data.


title:
Measurement of low mass dielectron continuum in sqrt(s_NN)=200GeV Au+Au
  collisions with the PHENIX experiment at RHIC

abstract:
  Electromagnetic probes are ideally suited to investigate hot and dense matter
produced in high energy heavy ion collisions. They do not undergo strong
interactions and thus probe the time evolution of the collision. The dielectron
continuum is rich in physics. Dalitz decays of light hadrons and direct decays
of vector mesons, which might be modified in the medium, and correlated charm
decays contribute to the spectrum. Furthermore, exotic states, e.g
quasi-particles predicted to exist in the medium only beyond the phase
transition, might leave their footprint in the continuum. Although correlated
e+e- pairs are rare, the 0.24 nb^-1 collected by PHENIX for Au+Au collisions at
sqrt(s_NN)= 200 GeV in 2004 provides a significant sample to investigate the
dilepton continuum. The continuum and its resonances are separated from the
combinatorial background via an event mixing technique. Mass spectra are
presented and compared with the expectations from decays of hadronic sources.


title: System and rapidity dependence of baryon to meson ratios at RHIC

abstract:
  The rapidity and centrality dependence of baryon to meson ratios in Au$+$Au,
Cu$+$Cu and p$+$p collisions at $\sqrt{s_{NN}}$ = 200 GeV at RHIC is presented.
The $\bar{p}/\pi^{-}$ ratios are founded to be independent of collision system
at a fixed $<N_{part}>$ at mid- and forward rapidities.

PHENIX Results on Open Heavy Flavor Production and Flow in Au + Au
  Collisions at sqrt(s_NN) = 200 GeV

abstract:
  The paper presents recent PHENIX results for the nuclear modification factor
R_AA in Au + Au Collisions at sqrt(s_NN) = 200 GeV for the electrons
originating from semi-leptonic decays of open heavy flavor carrying particles.
We also report the results of the azimuthal asymmetry (v_2) measurement for
those electrons, which is directly related to the heavy quark elliptic flow.


title:
Heavy flavor production in p+p and d+Au collisions at sqrt(sNN) = 200
  GeV from single leptons over a wide kinematic range

abstract:
  The PHENIX experiment at the Relativistic Heavy Ion Collider has measured
single electrons at midrapidity and single muons at forward and backward
rapidities (1.2<|y|< 2.2) for p+p and d+Au collisions at sqrt(sNN)=200 GeV. The
inclusive lepton spectra exhibit excesses over light hadron sources. The
excesses are attributed to semileptonic decays of charm and bottom hadrons and
compared to the perturbative QCD predictions. The NLO pQCD calculation
underpredicts the excess lepton production in {\it p+p} collisions. The excess
lepton production in {\it d+Au} collisions scales with $N_{coll}$ at
midrapidity, and shows suppression/enhancement relative to the same scaling in
d/Au-going direction within large uncertainties.


title: Open heavy flavor production from light ion collisions at RHIC

abstract:
  PHENIX measures leptons at mid and forward rapidities and extracts leptons
resulting from semi-leptonic decays of heavy quarks. We present PHENIX results
related to heavy quark production, specifically the invariant cross section of
the non-photonic single electrons produced at midrapidity in p+p and d+Au
collisions at sqrt(sNN) = 200 GeV. The measured cross section for {\it p+p}
collisions is compared with the NLO prediction, and a possible excess over the
prediction is noted. The measured cross section for {\it d+Au} collisions
scales with the number of colliding nucleon pairs from the {\it p+p} spectra.


title: R2D - The Case for a Comprehensive New RHIC-II Detector

abstract:
  A new detector concept (R2D) is needed to harvest the unique physics
opportunities at RHIC-II during the LHC era. This concept is based on a high
granularity hermetic array of detectors featuring high momentum particle
identification and superior resolution for photon and onium measurements. Most
components of R2D can also be applied to future electron-ion interactions.
Thus, R2D allows us to perform precision QCD-type measurements at RHIC-II and
eRHIC.


title: Identical Particle Correlations in STAR

abstract:
  Preliminary results of identical-particle correlations probing the geometric
substructure of the particle-emitting source at RHIC are presented. An
$m_T$-independent scaling of pion HBT radii from large (central Au+Au) to small
(p+p) collision systems naively suggests comparable flow strength in all of
them. Multidimensional correlation functions are studied in detail using a
spherical decomposition method. In the light systems, the presence of
significant long-range non-femtoscopic correlations complicates the extraction
of HBT radii.


title:
Gaseous Radiochemical Method for Registration of Ionizing Radiation and
  Its Possible Applications in Science and Industry

abstract:
  This work presents a new possibility of registration of ionizing radiation by
the flowing gaseous radiochemical method (FGRM). The specified method uses the
property of some solid crystalline lattice materials for a free emission of
radioactive isotopes of inert gas atoms formed as a result of nuclear
reactions. Generated in an ampoule of the detector, the radioactive inert gases
are transported by a gas-carrier into the proportional gas counter of the
flowing type, where the decay rate of the radioactive gas species is measured.
This quantity is unequivocally related to the flux of particles (neutrons,
protons, light and heavy ions) at the location of the ampoule. The method was
used to monitor the neutron flux of the pulsed neutron target "RADEX" driven by
the linear proton accelerator of INR RAS. Further progress of the FGRM may give
rise to possible applications in nuclear physics, astrophysics and medicine, in
the nondestructive control of fissionable materials, diagnostics of
thermonuclear plasma, monitoring of fluxes and measurement of spectra of
bombarding particles.


title:
phi production as seen in e+e- and K+K- decay channels in Au+Au
  collisions by PHENIX at sqrt{s_NN} = 200 GeV

abstract:
  The properties of the phi-meson have been measured via its e+e- and K+K-
decay channels in Au+Au collisions at sqrt{s_NN} = 200 GeV by the PHENIX
experiment. The preliminary yields and temperatures derived for the minimum
bias and several centrality bins in both decay channels are presented.


title: (Di)lepton physics with ALICE

abstract:
  Physics perspectives with(di)lepton measurements with the ALICE detector at
the LHC are reviewed. Special emphasis is placed on heavy flavor physics.


title:
Anisotropic Flow in sqrt(s_NN) = 200 GeV Cu+Cu and Au+Au collisions at
  PHENIX

abstract:
  We report the measurement of anisotropic flow at RHIC - PHENIX experiment. We
present the v_4 results at sqrt(s_NN) = 200 GeV in Au+Au collision. The scaling
ratio of v_4/(v_2)^2 is about 1.5 and it is found to be smaller than the
prediction from simple coalescence model. The v_2 for high p_T identified
particles ($\sim$ 5 GeV/c) measured with Aerogel Cherenkov Counter are
presented. We discuss the constituent quark scaling of v_2 for identified
particles. We also report the first observation of v_2 for inclusive charged
hadrons as well as identified hadrons at sqrt(s_NN) = 200 GeV in Cu+Cu
collisions. The system size dependence of v_2 and scaling properties are
discussed.


title:
From mach cone to reappeared jet: What do we learn from PHENIX results
  on non-identified jet correlation?

abstract:
  High $p_T$ jets are known to be strongly modified by the dense, strongly
interacting medium created in heavy-ion collisions. The jet signal, extracted
from two particle $\Delta\phi$ correlation, shows a systematic evolution of
these modifications as function of $p_T$ and centrality. At intermediate $p_T$,
both near side and away side correlations are modified. But the modifications
are much stronger at the away side, resulting in a characteristic cone type of
structure in central Au + Au collisions. The robustness of cone structure is
strengthened by studying the jet shape as function of angle relative to the
reaction plane. As one increase the $p_T$ for BOTH hadrons, the cone structure
seems to be filled up, and a peak structure appears on the away side. However,
the interpretation of these results require careful separation of medium effect
and surface bias.


title:
Study of $J/\psi$ Production in $\sqrt{s_{NN}} = 200$ GeV $p+p$ and
  $d+Au$ Collisions in PHENIX

abstract:
  $J/\psi$ measurements in $p+p$ and $d+Au$ collisions serve as crucial
references to understand the $J/\psi$ production in $Au+Au$ collisions at RHIC
where quark gluon plasma (QGP) is expected to be formed. They also provide
important clues to study various interesting phenomena such as the gluon
shadowing and color glass condensate. We report the latest results from PHENIX
experiment on $J/\psi$ production in $p+p$ and $d+Au$ collisions at forward,
backward and midrapidity.


title:
Jet Structure from Dihadron Correlations in d+Au collisions at
  sqrt(s_NN) = 200 GeV

abstract:
  Dihadron correlations at high transverse momentum in d+Au collisions at
sqrt(s_NN) = 200 GeV at midrapidity are measured by the PHENIX experiment at
the Relativistic Heavy Ion Collider (RHIC). From these correlations we extract
several structural characteristics of jets; the root-mean-squared (RMS)
transverse momentum of fragmenting hadrons with respect to the jet
sqrt(<j_T^2>), the mean sine-squared angle between the scattered partons
<sin^2(phi_jj)>, and the number of particles produced within the dijet that are
associated with a high-p_T particle (dN/dx_E distributions). We observe that
the fragmentation characteristics of jets in d+Au collisions are very similar
to those in p+p collisions and that there is also little dependence on the
centrality of the d+Au collision. This is consistent with the nuclear medium
having little influence on the fragmentation process. Furthermore, there is no
statistically significant increase in the value of <sin^2(phi_jj)> from p+p to
d+Au collisions. This constrains the amount of multiple scattering that partons
undergo in the cold nuclear medium before and after a hard-collision.


title: Systematic Study of Identified Particle Production in PHENIX

abstract:
  Large enhancement of (anti)protons relative to pions has been observed at
intermediate pT $\sim$ 2-5 GeV/c in central Au+Au collisions at RHIC. To
investigate the possible source of this baryon enhancement, we performed a
systematic study of identified hadron spectra in Au+Au and Cu+Cu collisions at
sqrt(s_NN) = 200 GeV, and Au+Au collisions at sqrt(s_NN) = 62.4 GeV. The data
set allows us to study the energy dependence and system size dependence of the
baryon enhancement. We also compare the nuclear modification factors on hadron
production in two different collision systems.


title:
High-pT pi0, eta, Identified and Inclusive Charged Hadron Spectra from
  PHENIX

abstract:
  PHENIX has extended the measurement of the pi0, eta, identified and inclusive
charged hadron up to 20 GeV/c, and extended the measurement to the Cu+Cu
collision system. A strong suppression is observed for both pi0 and charged
hadron yields in central Au+Au and Cu+Cu collisions. Comparing Au+Au and Cu+Cu
systems, RAA becomes independent of pT above 5 GeV/c. Its centrality dependence
is compared with two models in order to test for universal Npart scaling that
is independent of system; results are inconclusive. The results are compatible
with energy loss predictions. In addition, the ratio of eta to pi0 approaches,
within uncertainties, a constant value of 0.4-0.5 at high pT in p+p, d+Au, and
Au+Au, while the ratio of Ks to pi0 is also consistent with a constant value at
high pT in d+Au and p+p. These results are compatible with normal jet
fragmentation.


title: A Hadron Blind Detector for the PHENIX Experiment

abstract:
  A novel Hadron Blind Detector (HBD) has been developed for an upgrade of the
PHENIX experiment at RHIC. The HBD will allow a precise measurement of
electron-positron pairs from the decay of the light vector mesons and the
low-mass pair continuum in heavy-ion collisions. The detector consists of a 50
cm long radiator filled with pure CF4 and directly coupled in a windowless
configuration to a triple Gas Electron Multiplier (GEM) detector with a CsI
photocathode evaporated on the top face of the first GEM foil.


title: Studying QCD at low x and high mass with CMS

abstract:
  The CMS heavy ion program can study quark matter over an unprecedented range
of Bjorken x and mass. CMS is equipped with excellent detectors to exploit the
new physics probes available at_/Snn = 5.5 TeV. The high rate capability and
wide rapidity coverage will allow us to study the correlations between low x
and high mass phenomena.


title: Azimuthal Anisotropy of Identified Hadrons in 200 GeV Au+Au Collisions

abstract:
  The azimuthal anisotropy parameter v2 has been measured with high statistics
for identified hadrons in sqrt(s_NN) = 200 GeV Au+Au collisions with the STAR
experiment. At high transverse momentum (pT) a strong v2 for pi+ + pi- and p +
pbar is observed. In the intermediate pT region, number-of-constituent-quark
scaling was tested to high precision. A detailed comparison of v2 for the
multi-strange hadrons phi, Xi + anti-Xi, and Omega + anti-Omega with other
particle species substantiates the development of collectivity among partons in
the early phase of the collisions at RHIC.


title:
The azimuthal anisotropy of electrons from heavy flavor decays in
  sqrt(s_NN) = 200 GeV Au-Au collisions by PHENIX

abstract:
  The transverse momentum dependence of the azimuthal anisotropy parameter
v_{2}, the second harmonic of the azimuthal distribution, for electrons at
mid-rapidity (|eta|<0.35) has been measured with the PHENIX detector in Au+Au
collisions at sqrt(s_NN) = 200 GeV with respect to the reaction plane defined
at high rapidities (|eta|=3-4). From the result we have calculated non-photonic
electron v_{2}, which is expected to reflect the heavy-flavor azimuthal
anisotropy, by subtracting v_{2} of electrons from other sources such as photon
conversions, Dalitz decay etc.


title:
High transverse momentum inclusive neutral pion production in d+Au
  collisions at RHIC

abstract:
  Preliminary results are presented on high-pT inclusive neutral pion
production in d+Au collisions at sqrt(sNN) = 200 GeV in the pseudo-rapidity
range 0 < eta < 1. Photons from the decay pi0->gamma,gamma are detected in the
Barrel electromagnetic calorimeter of the STAR experiment at RHIC. The analysis
procedure is described in detail and the results are found to be in good
agreement with earlier STAR findings and with next-to-leading order
perturbative QCD calculations.


title:
The role of elliptic flow correlations in the discovery of the sQGP at
  RHIC

abstract:
  Flow measurements are reviewed with particular emphasis on the hydrodynamic
character of elliptic flow at RHIC. Hydrodynamic scaling compatible with the
production of highly thermalized matter having a high degree of collective
interactions and extremely low viscosity, is observed for a broad selection of
the data. These properties suggest the production of a new state of strongly
interacting nuclear matter at extremely high density and temperature where the
relevant degrees of freedom are those of quarks and gluons, ie. the sQGP.


title: Systematic Study of Directed Flow at RHIC Energies

abstract:
  Directed flow, v1, of charged hardons has been measured in Au-Au collisions
at RHIC for center-of-mass energies sqrt(sNN) = 19.6, 130, 62.4, and 200 GeV
using the PHOBOS detector. The large acceptance of PHOBOS for charged particles
allows measurements over the full range of pseudorapidity |eta| <5.4. The
results for a symmetric subevent method are shown at all four energies.
Comparison is made to a mixed harmonic method for the highest energy, and
compared to similar results from the STAR collaboration.


title:
System size, energy and pseudorapidity dependence of directed and
  elliptic flow at RHIC

abstract:
  PHOBOS measurements of elliptic flow are presented as a function of
pseudorapidity, centrality, transverse momentum, energy and nuclear species.
The elliptic flow in Cu-Cu is surprisingly large, particularly for the most
central events. After scaling out the geometry through the use of an
alternative form of eccentricity, called the participant eccentricity, which
accounts for nucleon position fluctuations in the colliding nuclei, the
relative magnitude of the elliptic flow in the Cu-Cu system is qualitatively
similar to that measured in the Au-Au system.


title: Electron Scattering From High-Momentum Neutrons in Deuterium

abstract:
  We report results from an experiment measuring the semi-inclusive reaction
$d(e,e'p_s)$ where the proton $p_s$ is moving at a large angle relative to the
momentum transfer. If we assume that the proton was a spectator to the reaction
taking place on the neutron in deuterium, the initial state of that neutron can
be inferred. This method, known as spectator tagging, can be used to study
electron scattering from high-momentum (off-shell) neutrons in deuterium. The
data were taken with a 5.765 GeV electron beam on a deuterium target in
Jefferson Laboratory's Hall B, using the CLAS detector. A reduced cross section
was extracted for different values of final-state missing mass $W^{*}$,
backward proton momentum $\vec{p}_{s}$ and momentum transfer $Q^{2}$. The data
are compared to a simple PWIA spectator model. A strong enhancement in the data
observed at transverse kinematics is not reproduced by the PWIA model. This
enhancement can likely be associated with the contribution of final state
interactions (FSI) that were not incorporated into the model. A ``bound neutron
structure function'' $F_{2n}^{eff}$ was extracted as a function of $W^{*}$ and
the scaling variable $x^{*}$ at extreme backward kinematics, where effects of
FSI appear to be smaller. For $p_{s}>400$ MeV/c, where the neutron is far
off-shell, the model overestimates the value of $F_{2n}^{eff}$ in the region of
$x^{*}$ between 0.25 and 0.6. A modification of the bound neutron structure
function is one of possible effects that can cause the observed deviation.


title:
Measurement of $\Delta$ and $K^{*}$ Production in $d$+Au collisions at
  $\sqrt{s_{NN}}$ = 200 GeV

abstract:
  The measurements of the transverse momentum spectra and the invariant mass
distributions of $\Delta(1232)$ $\to \pi p$, $K^{*}(892)\to \pi K$ resonances
in $d$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV using the STAR Time
Projection Chamber (TPC) at RHIC are presented. The in-medium modification of
the $\Delta$ and $K^{*}$ mass and width has been studied as a function of
transverse momentum ($p_T$). The particle ratios $K^{*}/K$, $\Delta/p$ and the
average transverse momentum ($<p_{T}>$) as a function of different collision
centrality has been reported. The nuclear modification factors ($R_{CP}$ and
$R_{dAu}$) of $\Delta$ and $K^{*}$ are discussed.


title: Anisotropic flow in AuAu and CuCu at 62 GeV and 200 GeV

abstract:
  We present STAR's measurements of directed flow (v_1) and elliptic flow (v_2)
for charged hadrons in AuAu collisions at 62 and 200 GeV, as a function of
pseudorapidity, p_t and centrality. v_2 results in CuCu collisions at 200 GeV
are also presented.


title: Low-$Q^2$ partons in p-p and Au-Au collisions

abstract:
  We describe correlations of low-$Q^2$ parton fragments on transverse rapidity
$y_t$ and angles $(\eta,\phi)$ from p-p and Au-Au collisions at $\sqrt{s} =$
130 and 200 GeV. Evolution of correlations on $y_t$ from p-p to more-central
Au-Au collisions shows evidence for parton dissipation. Cuts on $y_t$ isolate
angular correlations on $(\eta,\phi)$ for low-$Q^2$ partons which reveal a
large asymmetry about the jet thrust axis in p-p collisions favoring the
azimuth direction. Evolution of angular correlations with increasing Au-Au
centrality reveals a rotation of the asymmetry to favor pseudorapidity. Angular
correlations of transverse momentum $p_t$ in Au-Au collisions access
temperature/velocity structure resulting from low-$Q^2$ parton scattering.
$p_t$ autocorrelations on $(\eta,\phi)$, obtained from the scale dependence of
$<p_t>$ fluctuations, reveal a complex parton dissipation process in heavy ion
collisions which includes the possibility of collective bulk-medium recoil in
response to parton stopping.


title:
Forward-Backward Multiplicity Correlations in sqrt(s_NN)=200 GeV Au+Au
  Collisions

abstract:
  Forward-backward correlations of charged-particle multiplicities in symmetric
bins in pseudorapidity (eta) are studied in order to gain insight into the
underlying correlation structure of particle production in Au+Au collisions.
The PHOBOS detector is used to measure integrated multiplicities in bins
defined within eta<3, centered at eta and covering an interval Delta-eta. The
variance (sigma^2_C) of a suitably defined forward-backward asymmetry variable
is calculated as a function of eta, Delta-eta, and centrality. It is found to
be sensitive to short range correlations, and the concept of ``clustering'' is
used to interpret comparisons to phenomenological models.


title:
Evidence for a long range structure in the pion emission source in Au+Au
  collisions at RHIC

abstract:
  The PHENIX experiment, has recently acquired $\sim$ 1 billion minimum bias
Au+Au events at $\sqrt s = 200$GeV during the year-2004 run. This high
statistics data set, coupled with a state-of-the-art analysis technique, allows
for the extraction of 3D emission sources for various particle types. These 3D
sources lend fresh insight into the nature of a long-range source previously
reported by PHENIX. The new results indicate an anisotropic pion emission
source in the pair c.m. having an extended space-time extent oriented in the
outward direction. The two-proton emission source from the same data set is
essentially isotropic the pair c.m. frame. These results provide a "window" for
viewing the evolution dynamics of the high energy density nuclear matter
created at RHIC.


title:
Nuclear modification factor for identified hadrons at forward rapidity
  in Au+Au reactions at 200 GeV

abstract:
  Herewith we present the production of identified hadrons in Au+Au and p+p
collisions at $\sqrt{s_{NN}}=200 {\rm GeV}$ at forward rapidity, $y \approx
3.2$. Suppression of pions and kaons and enhancement for protons in central
Au+Au collisions is observed. These results are found to be very similar in
strength to that observed at mid-rapidity. Furthermore, we see a gradual
decrease of the observed suppression towards more peripheral collisions.


title:
Particle production at very low and intermediate transverse momenta in
  d+Au and Au+Au collisions

abstract:
  The transverse momentum spectra of identified charged particles have been
measured at very low and intermediate transverse momenta in Au+Au collisions at
sqrt(s_NN) = 62.4 GeV and d+Au collisions at sqrt(s_NN) = 200 GeV using the
PHOBOS detector at RHIC. New results on charged particle production at very low
p_T in central Au+Au collisions at sqrt(s_{NN) = 200 GeV in the centrality
intervals 0-6% and 6-15% are presented. A comparison of the PHOBOS low-p_T data
with predictions of a recent optical model is shown. The shapes of m_T spectra
for d+Au and Au+Au collisions are compared.


title: Two and Three Particle Flavor Dependent Correlations

abstract:
  The PHENIX collaboration has developed novel methodologies for reliable
extraction of jet functions from two and three particle azimuthal correlation
functions measured at mid-rapidity in Au+Au collisions at $\sqrt s=200$ GeV.
The extracted jet shape and the yield of jet-associated partner hadrons (per
trigger hadron) are found to vary with particle type and collision centrality,
indicating a significant effect of the nuclear collision medium on the (di)jet
fragmentation process.

Comments on the PLA article 'UCN anomalous losses and the UCN capture
  cross section on material defects' [Phys. Lett. A 335 (2005) 327]

abstract:
  We comment on the paper `UCN anomalous losses and the UCN capture cross
section on material defects' by A. Serebrov et al., Phys. Lett. A 335 (2005)
327 - 336. Data presented do not originate from these authors alone but were
taken in collaboration with several other authors and institutes not mentioned.


title: New results from the PHOBOS experiment

abstract:
  Over the past five years, PHOBOS has collected data on proton-proton,
deuteron-gold, Au+Au and Cu+Cu collisions, covering a wide range of collision
energy, collision centrality and system size. Using these data, we have
identified scaling features that are common for all types of high-energy
collisions, as well as collective effects that are unique to the conditions
created in collisions of relativistic nuclei. In this paper, we will focus on
recent results obtained for collisions of Cu nuclei. Both in terms of universal
features of particle production, and in the development of truly collective
effects, the results for Cu nuclei confirm and extend our present understanding
of nuclear collisions at the highest energies. In addition, we will describe
recent unique results on multiplicity fluctuations and particle production at
very low transverse momenta.


title:
Measurement of event-by-event fluctuations and order parameters in
  PHENIX

abstract:
  We present the latest results on event-by-event fluctuations of charged
particle multiplicity in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}} = 200$
GeV and 62.4 GeV measured by PHENIX experiment at RHIC. The two particle
correlation length to discuss order parameters, which can be extracted from
scale dependence of the fluctuations, is supposed to be sensitive to the
critical points of QCD phase transition. The obtained correlation length with
respect to the pseudo rapidity gap indicates the power law behavior as a
function of the number of participant nucleons for Au+Au collisions at
$\sqrt{s_{NN}} = 200$ GeV.


title: First measurement of the rho spectral function in nuclear collisions

abstract:
  The NA60 experiment has studied low-mass muon pairs in 158 AGeV Indium-Indium
collisions at the CERN SPS. A strong excess of pairs is observed above the
expectation from neutral meson decays. The unprecedented sample size of 360 000
events and the good mass resolution of about 2% allow to isolate the excess by
subtraction of the known sources. The shape of the resulting mass spectrum is
consistent with a dominant contribution from pi+ pi- -> rho -> mu+ mu-
annihilation. The associated rho spectral function shows a strong broadening,
but essentially no shift in mass.


title:
Energy and rapidity dependence of electric charge correlations at
  20-158GeV beam energies at the CERN SPS (NA49)

abstract:
  Electric charge correlations are studied with the Balance Function method for
central Pb + Pb collisions at the CERN - SPS. The results on centrality
selected Pb + Pb interactions at 40 and 158 AGeV are presented for the first
time for two different rapidity intervals. In the mid-rapidity region a
decrease of the width with increasing centrality of the collision is observed
whereas in the forward rapidity region this effect vanishes. This could suggest
a delayed hadronization scenario. In addition, the results from a first attempt
to study the energy dependence of the Balance Function throughout the whole SPS
energy range, are presented. The suitably scaled decrease of the width is
approximately constant for the intermediate energies (30 to 80 AGeV) and gets
stronger for the highest SPS and RHIC energies. On the other hand, both URQMD
and HSD simulation results show no dependence on the collision energy.


title:
Azimuthal correlations of high-pT photons and hadrons in Au+Au
  collisions at RHIC

abstract:
  The measurement of gamma+jet events with a direct photon in coincidence with
an energetic parton can provide unique insights into the propagation and
fragmentation of the parton in the presence of the hot and dense medium created
in heavy-ion collisions. One way to explore these effects is the study of
azimuthal correlations between the direct photon and hadrons produced in the
fragmentation.
  We present azimuthal correlations between photons with a transverse momentum
of more than 10 GeV and charged hadrons with a transverse momentum of more than
2 GeV in Au+Au collisions at sqrt(s_NN) = 200 GeV that have been measured with
the STAR detector at RHIC. The separation of correlations with direct photons
and photons from hadronic decays will be discussed.


title:
Nuclear Modification of Electron Spectra and Implications for Heavy
  Quark Energy Loss in Au+Au Collisions at sqrt(s_NN)=200 GeV

abstract:
  The PHENIX experiment has measured mid-rapidity transverse momentum spectra
(0.4 < p_T < 5.0 GeV/c) of electrons as a function of centrality in Au+Au
collisions at sqrt(s_NN)=200 GeV. Contributions from photon conversions and
from light hadron decays, mainly Dalitz decays of pi^0 and eta mesons, were
removed. The resulting non-photonic electron spectra are primarily due to the
semi-leptonic decays of hadrons carrying heavy quarks. Nuclear modification
factors were determined by comparison to non-photonic electrons in p+p
collisions. A significant suppression of electrons at high p_T is observed in
central Au+Au collisions, indicating substantial energy loss of heavy quarks.


title: Structure of 12Be: intruder d-wave strength at N=8

abstract:
  The breaking of the N=8 shell-model magic number in the 12Be ground state has
been determined to include significant occupancy of the intruder d-wave
orbital. This is in marked contrast with all other N=8 isotones, both more and
less exotic than 12Be. The occupancies of the 0 hbar omega neutron p1/2-orbital
and the 1 hbar omega, neutron d5/2 intruder orbital were deduced from a
measurement of neutron removal from a high-energy 12Be beam leading to bound
and unbound states in 11Be.


title: Results from NA49

abstract:
  An overview of results from the CERN experiment NA49 is presented with
emphasis on most recent measurements. NA49 has systematically studied the
dependence of hadron production on energy and system size or centrality. At
top-SPS energy the detailed investigation of hadron production, now also
extending to elliptic flow of Lambda-baryons and to identified particle yields
at high p_t, shows that the created matter behaves in a similar manner as at
RHIC energies. In the lower SPS energy range a distinct structure is observed
in the energy dependence of the rate of strangeness production and in the
slopes of p_t-spectra suggesting the onset of the creation of a deconfined
phase of matter.


title:
Tensor Ayy and vector Ay analyzing powers in the H(d,d')X and
  ^{12}C(d,d')X reactons at initial deuteron momenta of 9 GeV/c in the region
  of baryonic resonances excitation

abstract:
  The angular dependence of the tensor Ayy and vector Ay analyzing powers in
the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen
and carbon have been measured. The range of measurements corresponds to the
baryonic resonance excitation with masses 2.2--2.6 GeV/c^2. The Ayy data being
in good agreement with the previous results demonstrate an approximate $t$
scaling up to -1.5 (GeV/c)^2. The large values of A_y show a significant role
of the spin-dependent part of the elementary amplitude of the NN->NN* reaction.
The results of the experiment are compared with model predictions of the
plane-wave impulse approximation.


title:
PHENIX results on jpsi production in Au+Au and Cu+Cu collisions at
  $\sqrt{s_{NN}}$=200 GeV

abstract:
  Heavy quarkonia production is predicted to be sensitive to the formation of
the quark gluon plasma in relativistic heavy ion collisions via competing
mechanisms such as color screening and/or quark recombination. During 2004 and
2005 RHIC data taking periods, the PHENIX collaboration has measured jpsi decay
into lepton pairs both at mid and forward rapidity in Au+Au and Cu+Cu
collisions at $\sqrt{s_{NN}}$=200 GeV. We present the jpsi nuclear modification
factor and the $\jpsi$ mean square transverse momentum as a function of the
collision centrality for both systems, as well as the rapidity dependence of
the jpsi yield for different centrality classes. It is compared to different
theoretical predictions. All Au+Au and Cu+Cu results shown here are
preliminary.


title: Identified Particle Spectra and Jet Interactions with the Medium

abstract:
  Through a combination of detector upgrades and advancements in analysis
techniques, physicist at RHIC are extending their ability to identify particles
at high pT . With these new capabilities some outstanding questions are being
addressed: particularly regarding baryon production. Here I present an overview
of new data on identified particle elliptic flow (v2), identified particle pT
spectra and identified hadron-hadron correlations. The observed phenomena
provide insights into hard parton interactions with the bulk matter created in
heavy-ion collisions and the relevant degrees-of-freedom during its early
stages.


title: Directed flow in Au+Au collisions at $\sqrt{s_{_{NN}}}$ =62.4 GeV

abstract:
  We present the directed flow ($v_1$) measured in Au+Au collisions at
$\sqrt{s_{_{NN}}}$ = 62.4 GeV in the mid-pseudorapidity region $|\eta|<1.3$ and
in the forward pseudorapidity region $2.5 < |\eta| < 4.0$. The results are
obtained using the three-particle cumulant method, the event plane method with
mixed harmonics, and for the first time at the Relativistic Heavy Ion Collider
(RHIC), the standard method with the event plane reconstructed from spectator
neutrons. Results from all three methods are in good agreement. Over the
pseudorapidity range studied, charged particle directed flow is in the
direction opposite to that of fragmentation neutrons.


title:
High p_T Spectra of Identified Particles Produced in Pb+Pb Collisions at
  158GeV/nucleon Beam Energy

abstract:
  Transverse momentum spectra of pi^{+/-}, p, pbar, K^{+/-}, K^0_s and Lambda
at midrapidity were measured at high p_T in Pb+Pb collisions at 158GeV/nucleon
beam energy by the NA49 experiment. Particle yield ratios (p/pi, K/pi and
Lambda/K^0_s) show an enhancement of the baryon/meson ratio for p_T>2GeV/c. The
nuclear modification factor R_{CP} is extracted and compared to RHIC
measurements and pQCD calculations.


title: Two- and Three-Particle Jet Correlations from STAR

abstract:
  Hard-soft charged hadron angular correlations are shown. Away-side associated
$<p_T>$ is studied. Angular correlations with trigger baryon and meson are
compared. Three-particle correlations are presented for the first time.


title: Near threshold eta meson production in the d+d->alpha+eta reaction

abstract:
  The d+d->alpha+eta reaction has been investigated near threshold using the
ANKE facility at COSY-Juelich. Both total and differential cross sections have
been measured at two excess energies, Q=2.6 MeV and 7.7 MeV, with a
subthreshold measurement being undertaken at Q=-2.6 MeV to study the physical
background. While consistent with isotropy at the lower energy, the angular
distribution reveals a pronounced anisotropy at the higher one, indicating the
presence of higher partial waves. Options for the decomposition into partial
amplitudes and their consequences for determination of the s-wave eta-alpha
scattering length are discussed.


title:
Strange and charged particle elliptic flow in Pb+Au collisions at 158
  AGeV/c

abstract:
  We present $\Lambda$ and $\pi$ elliptic flow measurements from Pb+Au
collisions at the highest SPS energy. The data, collected by the CERES
experiment which covers $\eta=2.05,2.70$ with full azimuthal coverage and wide
$p_{T}$ sensitivity up to 3.5 GeV/c, can be used to test hydrodynamical models
and show sensitivity to the EoS. The value of $v_{2}$ as a function of
centrality and $p_{T}$ is presented. Values of $v_{2}$ observed by STAR at RHIC
are larger by about 1/3. Our measurements are compared to results from other
SPS experiments and to hydrodynamical calculations. Huge statistics allows for
a precise measurement of the differential pion elliptic flow.


title: On a cryogenic noble gas ion catcher

abstract:
  In-situ purification of the gas used as stopping medium in a noble gas ion
catcher by operating the device at low temperatures of 60 to 150 K was
investigated. Alpha-decay recoil ions from a 223Ra source served as energetic
probes. The combined ion survival and transport efficiencies for 219Rn ions
saturated below about 90 K, reaching 28.7(17) % in helium, 22.1(13) % in neon,
and 17.0(10) % in argon. These values may well reflect the charge exchange and
stripping cross sections during the slowing down of the ions, and thus
represent a fundamental upper limit for the efficiency of noble gas ion catcher
devices. We suggest the cryogenic noble gas ion catcher as a technically
simpler alternative to the ultra-high purity noble gas ion catcher operating at
room temperature.


title:
Transverse energy measurement in sqrt{s_{NN}} = 62.4 GeV Au+Au
  collisions at RHIC

abstract:
  The transverse energy distributions ($E_{T}$) have been measured for Au + Au
collisions at $\sqrt{s_{NN}} = 62.4$ GeV by the STAR experiment at RHIC. They
have been obtained from two measurements, the hadronic transverse energy
($E_{T}^{had}$) and the electromagnetic transverse energy($E_{T}^{em}$).
$E_{T}^{had}$ has been measured from the tracks obtained by Time Projection
Chamber (TPC) excluding the electrons and positrons. $E_{T}^{em}$ has been
obtained by the STAR Barrel Electromagetic Calorimeter (BEMC) which measures
the energy of electrons, positrons and photons. The measure of transverse
energy gives an estimate of the energy density of the fireball produced in
heavy ion collisions. $E_{T}$ per participant pair gives information about the
production mechanism of particles.


title: Di-jet correlation in Au + Au and Cu + Cu collisions from PHENIX

abstract:
  PHENIX has measured the two particle azimuth correlation in Au + Au at
$\sqrt{s}$ = 200 GeV. Jet shape and yield at the away side are found to be
strongly modified at intermediate and low $p_T$. The modifications vary
dramatically with $p_T$ and centrality. At high $p_T$, away side jet peak
reappears but the yield is suppressed. Similar jet strength is found for Au +
Au and Cu + Cu collisions with similar number of participant nucleons.


title: Recent Results from the BRAHMS Experiment

abstract:
  We present recent results obtained by the BRAHMS experiment at the
Relativistic Heavy Ion Collider (RHIC) for the systems of Au + Au and Cu + Cu
at \rootsnn{200} and at 62.4 GeV, and p + p at \rootsnn{200}. Nuclear
modification factors for Au + Au and Cu + Cu collisions are presented. Analysis
of anti-particle to particle ratios as a function of rapidity and collision
energy reveal that particle populations at the chemical freeze-out stage for
heavy-ion reactions at and above SPS energies are controlled by the baryon
chemical potential. From the particle spectra we deduce significant radial
expansion ($\beta \approx $ 0.75), as expected for systems created with a large
initial energy density. We also measure the elliptic flow parameter $v_2$
versus rapidity and \ptn. We present rapidity dependent $p/\pi$ ratios within
$0 < y < 3$ for Au + Au and Cu + Cu at \rootsnn{200}. \Raa is found to increase
with decreasing collision energy, decreasing system size, and when going
towards more peripheral collisions. However, \Raa shows only a very weak
dependence on rapidity (for $0 < y < 3.2$), both for pions and protons.


title: Jet quenching: RHIC results and phenomenology

abstract:
  I review the main experimental results on jet physics in high-energy
nucleus-nucleus collisions as studied via inclusive leading hadron spectra and
di-hadron correlations at high transverse momentum. In central Au+Au at RHIC
(sqrt(s_NN) = 200 GeV), the observed large suppression of high-$p_T$ hadron
spectra as well as the strongly modified azimuthal dijet correlations compared
to baseline p+p results in free space, provide crucial information on the
thermodynamical and transport properties of QCD matter.


title: Open Charm Production in sqrt(s_(NN))=200 GeV Au+Au Collisions at STAR

abstract:
  We present first results on D^0 meson production via direct reconstruction of
its hadronic decay channel D^0->K pi in minimum bias Au+Au collisions at
sqrt(s_(NN))=200 GeV with p_T up to ~3 GeV/c. Single electron spectra with
1<p_T<4 GeV/c from the charm semi-leptonic decays are also analyzed from the
same data set. The charm production total cross-section per nucleon-nucleon
collision is measured to be 1.11+/-0.08(stat.)+/-0.42(sys.) mb in minimum bias
Au+Au collisions, which is consistent with the N_(bin) scaling compared to d+Au
collisions. The nuclear modification factors of the single electrons in minimum
bias and 0-20% Au+Au collisions are significantly below unity at 1<p_T<4 GeV/c.


title: Non-identical particle correlations at 62 and 200 GeV at STAR

abstract:
  We report on STAR analyses of p-lambda, p_bar-lambda_bar, p-lambda_bar,
p_bar-lambda, p-p_bar and pi-Xi correlations in Au+Au collisions at
sqrt(S_NN)=62 and 200 GeV. Measured source sizes in p(p_bar)-lambda(lambda_bar)
and p-p_bar are shown to be in qualitative agreement with flow expectations.
Interaction potential between p-lambda_bar, p_bar-lambda was investigated by
measuring scattering length, thus showing that correlation analyses in
heavy-ion collisions can be used to study strong interaction potential between
hadrons. We present also analyses of pi-Xi correlations addressing
independently on previous measurements the issue of Xi flow in heavy-ion
collisions.


title:
Jet Study in Ultra-Relativistic Heavy-Ion Collisions with the ALICE
  Detectors at the LHC

abstract:
  In ultra-relativistic heavy-ion collisions at $\sqrt{s_{NN}}$ = 5.5 TeV at
the ALICE experiment at the LHC, interactions between the high-$p_{T}$ partons
and the hot, dense medium produced in the collisions, are expected to lead to
jet energy loss (jet-quenching) resulting in changes in the jet fragmentation
functions as compared to the unquenched case. In order to reconstruct jet
fragmentation functions, accurate information on the jet energy, direction and
momentum distribution of the jet particles is needed. This thesis presents
first results on jet reconstruction in simulated Pb+Pb collisions using the
ALICE detectors and a UA1-based cone jet finding algorithm which has been
modified and optimised to reconstruct high-$p_{T}$ jets on an event-by-event
basis. Optimisation of the algorithm parameters and methods used to suppress
the large background energy contribution while maximising the algorithm
efficiency, are discussed and the resulting jet energy and direction
resolutions are presented. Accurate jet reconstruction will allow measurement
of the jet fragmentation functions and consequently the degree of quenching and
therefore provide insight on the properties of the hot and dense medium (for
example the initial gluon density) created in the collisions.


title:
Correlations and Fluctuations over a Broad Range in Pseudorapidity using
  the PHOBOS Detector

abstract:
  The PHOBOS apparatus includes a charged particle multiplicity detector
covering almost all of 4pi in solid angle. The broad coverage in
pseudorapidity, $\eta$, which is unique at RHIC, combined with the ability to
collect a large sample of events with minimal bias, makes possible a study of
correlations and fluctuations over most of the pseudorapidity range, even at
the highest beam energy. Long range correlations, short range correlations at
large |eta|, event-by-event fluctuations in the total number of charged
particles, and event-by-event variation in the full shape of the pseudorapidity
distribution can all be studied. Preliminary results for the first exploration
of these capabilities of the PHOBOS detector, along with some average
properties of the pseudorapidity distributions, are presented.


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

abstract:
  The elliptic flow of Lambda hyperons has been measured by the NA49 experiment
in semi-central Pb+Pb collisions at 158 AGeV. The standard method of
correlating particles with an event plane has been 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 models predictions.


title: Soft Physics from STAR

abstract:
  New results on soft hadron distributions and correlations measured with the
STAR experiment are presented. Knowledge about the bulk properties of
relativistic heavy-ion collisions offered by these results is discussed.


title: Global polarization and parity violation study in Au+Au collisions

abstract:
  We present results on the parity violation effects and global system
polarization measurements in Au+Au collisions at sqrt(s_NN) = 62 GeV obtained
with the STAR detector at RHIC. The parity violation effects are studied by
three particle azimuthal correlations of charged particles. The global
polarization of the system is examined by measuring the polarization of strange
hyperons with respect to the collision reaction plane.


title: Next stage of search for 2K(2$\nu$)-capture of $^{78}$Kr

abstract:
  A technique to search for 2K-capture of $^{78}$Kr with large low-background
proportional counter filled with an enriched in $^{78}$Kr up to 99.8% sample of
Krypton at a pressure of 4.51 is described in this paper. The results of first
measurements are presented. Analysis of data collected during 159 hours yielded
new limit to the half-life of $^{78}$Kr with regard to 2K-capture
(T$_{1/2}\geq6\cdot10^{21}$ yr (90% C.L.)). Sensitivity of the facility to the
process for one year of measurement was evaluated to be
$\texttt{S}=1.0\cdot10^{22}$ yr (90% C.L.).


title:
Results of a search for 2$\beta$-decay of $^{136}$Xe with high-pressure
  copper proportional counters in Baksan Neutrino Observatory

abstract:
  The experiment for the 2$\beta$-decay of $^{136}$Xe search with two
high-pressure copper proportional counters has been held in Baksan neutrino
observatory. The search for the process is based on comparison of spectra
measured with natural and enriched xenon. No evidence has been found for
2$\beta$(2$\nu$)- and 2$\beta$(0$\nu$)-decay. The decay half lifetime limit
based on data measured during 8000 h is T$_{1/2}$$\geq8.5\cdot10^{21}$yr for
2$\nu$-mode and T$_{1/2}$$\geq3.1\cdot10^{23}$yr for 0$\nu$-mode (90%C.L.).


title: Characterization of a ballistic supermirror neutron guide

abstract:
  We describe the beam characteristics of the first ballistic supermirror
neutron guide H113 that feeds the neutron user facility for particle physics
PF1B of the Institute Laue-Langevin, Grenoble (ILL). At present, the neutron
capture flux density of H113 at its 20x6cm2 exit window is 1.35x10^10/cm^2/s,
and will soon be raised to above 2x10^10/cm^2/s. Beam divergence is no larger
than beam divergence from a conventional Ni coated guide. A model is developed
that permits rapid calculation of beam profiles and absolute event rates from
such a beam. We propose a procedure that permits inter-comparability of the
main features of beams emitted from ballistic or conventional neutron guides.


title: Hard Probes with the STAR Experiment

abstract:
  Recent results on the use of hard probes in heavy ion collisions by the STAR
experiment at RHIC are reviewed. The increased statistical reach from RHIC run
4 and utilization of the full capabilities of the STAR experiment have led to a
qualitative improvement in these results. Light hadrons have been identified
out to transverse momenta ($p_T$) of 12 GeV/c, allowing for clear
identification of the dominant processes governing particle production in
different $p_T$ windows. Clean signatures of dijets have been seen even in
central Au+Au collisions. Nuclear modification factors for non-photonic
electrons, predominantly from the decay of heavy-flavored hadrons, have also
been measured out to $p_T$ of 8 GeV/c. For $p_T > \sim 6$ GeV/c, inclusive
spectra of all charged hadrons, including heavy-flavored ones, appear to be
suppressed equally strongly (by a factor of four to five) in central Au+Au
collisions relative to p+p collisions; interestingly enough, the probability of
finding a hadron from a dijet partner is suppressed to this same level.


title: Scintillating double beta decay bolometers

abstract:
  We present the results obtained in the development of scintillating Double
Beta Decay bolometers. Several Mo and Cd based crystals were tested with the
bolometric technique. The scintillation light was measured through a second
independent bolometer. A 140 g CdWO_4 crystal was run in a 417 h live time
measurement. Thanks to the scintillation light, the alpha background is easily
discriminated resulting in zero counts above the 2615 keV gamma line of
Thallium 208. These results, combined with an extremely easy light detector
operation, represent the first tangible proof demonstrating the feasibility of
this kind of technique.


title:
Dissipation and fragmentation of low-Q^2 scattered partons in Au-Au
  collisions at RHIC

abstract:
  Two-particle correlations and event-wise fluctuations in transverse momentum
p_t are reported for Au-Au collisions at sqrt{s_{NN}} = 62 and 200 GeV on
pseudorapidity (eta) and azimuth (phi). Distributions of all pairs of particles
(no leading trigger particle) reveal jet-like correlations, or peaks at
pair-wise opening angles of order 1 radian or less. The width of this same-side
correlation peak increases dramatically on pseudorapidity and decreases on
azimuth for increasing collision centrality. Evolution of the same-side peak
with centrality suggests dissipation of low-Q^2 partons via strong coupling to
an expanding bulk medium. p_t correlations, which provide access to temperature
and/or velocity distributions in the colliding system, are also presented.


title: A Survey of Multiplicity Fluctuations in PHENIX

abstract:
  The PHENIX Experiment at the Relativistic Heavy Ion Collider has made
measurements of event-by-event fluctuations in the charged particle
multiplicity as a function of collision energy, centrality, collision species,
and transverse momentum in heavy ion collisions. The results of these
measurements will be reviewed and discussed.


title: Has the Quark-Gluon Plasma been seen?

abstract:
  Data from the first three years of running at RHIC are reviewed and put into
context with data obtained previously at the AGS and SPS and with the physics
question of creation of a quark-gluon plasma in high energy heavy ion
collisions. Also some very recent and still preliminary data from run4 are
included.


title: Review of Recent Jlab Results

abstract:
  High quality polarized electron beams at Jefferson Lab make possible
precision measurements of hadronic properties in the regime of strongly
interacting QCD. We will describe a few programs at Jefferson Lab that are
making measurements that link the basic static properties of hadrons to their
quark sub-structure. For example, parity-violating electron proton elastic
scattering probes the spatial distribution of strange quarks in the nucleon.
The nucleon-Delta transition form factors give us information about the
deformation of nucleons and Deltas. Finally, new high statistics measurements
of photons scattering off proton and deuteron targets are used to set upper
limits on the production of exotic baryons with strangeness S=+1. These
examples will be used to illustrate the capabilities and focus of the
experimental program at JLab.


title: Photon measurements in forward rapidity in heavy-ion collisions

abstract:
  Contribution of a preshower photon multiplicity detector to the physics of
ultra-relativistic nuclear collisions is reviewed and future possibilities at
RHIC and LHC are discussed


title: Di-jet Shape Modification in Heavy Ion Collisions

abstract:
  We present preliminary results from intermediate $p_T$ (1-5 GeV/c) di-hadron
azimuthal correlations induced by hadronic di-jets produced in $AuAu$
collisions at $\sqrt{s_{NN}} = 200 GeV$. The near side ($\Delta\phi\sim 0$) has
a typical single-peaked structure which broadens with the centrality of the
collision. A qualitatively new phenomenon shows up in the shape of the away
side ($\Delta\phi\sim\pi$): it has a symmetric, double-peaked structure in
central and mid-central collisions.


title: Status of the Standard Solar Model Prediction of Solar Neutrino Fluxes

abstract:
  The Standard Solar Model (BP04) predicts a total 8B neutrino flux that is
17.2% larger than measured in the salt phase of the SNO detector (and if it
were significant it will indicate oscillation to sterile neutrinos). Hence it
is important to examine in details uncertainties (and values) of inputs to the
SSM. Currently, the largest fractional uncertainty is due to the new evaluation
of the surface composition of the sun. We examine the nuclear input on the
formation of solar 8B [S17(0)] and demonstrate that it is still quite uncertain
due to ill known slope of the measured astrophysical cross section factor and
thus ill defined extrapolation to zero energy. This yields an additional
reasonably estimated uncertainty due to extrapolation of +0.0 -3.0 eV-b (+0%
-14%). Since a large discrepancy exists among measured as well as among
predicted slopes, the value of S17(0) is dependent on the choice of data and
theory used to extrapolate S17(0). This situation must be alleviated by new
measurement(s). The "world average" is driven by the Seattle result due to the
very small quoted uncertainty, which we however demonstrate it to be an
over-estimated accuracy. We propose more realistic error bars for the Seattle
results based on the published Seattle data.


title: Open heavy flavour production in ALICE

abstract:
  After a short review of the physics motivations for the study of open heavy
flavour production in proton-proton, proton-nucleus and nucleus-nucleus
collisions at the LHC, we present results on the expected performance of the
ALICE experiment for charm and beauty production measurements.


title:
Measuring beauty production in Pb-Pb collisions at the LHC via single
  electrons in ALICE

abstract:
  We present the expected ALICE performance for the measurement of the
p_t-differential cross section of electrons from beauty decays in central Pb-Pb
collisions at the LHC.


title:
Diffractive J/$\psi$ production in Ultraperipheral AuAu Collisions at
  RHIC

abstract:
  We report on the first measurement of diffractive J/psi production in
Ultraperipheral Au+Au collisions at \sqrt{s_{NN}}=200 GeV.


title:
Measurement of neutral pions in $\sqrt{s_\mathrm{NN}}$=200GeV and
  62.4GeV Au+Au collisions at RHIC-PHENIX

abstract:
  Neutral pions ($\pi^0$) in $\sqrt{s_\mathrm{NN}}$ = 200 GeV and 62.4 GeV
Au+Au collisions were measured at RHIC-PHENIX Year-4 Run. In
$\sqrt{s_\mathrm{NN}}$ = 200 GeV, $\pi^0$ specta are measured up to
p$_\mathrm{T}$ = 20 GeV/$c$. %PHENIX extended the p$_\mathrm{T}$ region of A
strong suppression by a factor of $\sim$ 5 is observed and stays almost
constant up to 20 GeV/$c$.


title:
Measurement of the Intrinsic Radiopurity of Cs-137/U-235/U-238/Th-232 in
  CsI(Tl) Crystal Scintillators

abstract:
  The inorganic crystal scintillator CsI(Tl) has been used for low energy
neutrino and Dark Matter experiments, where the intrinsic radiopurity is an
issue of major importance. Low-background data were taken with a CsI(Tl)
crystal array at the Kuo-Sheng Reactor Neutrino Laboratory. The pulse shape
discrimination capabilities of the crystal, as well as the temporal and spatial
correlations of the events, provide powerful means of measuring the intrinsic
radiopurity of Cs-137 as well as the U-235, U-238 and Th-232 series. The event
selection algorithms are described, with which the decay half-lives of Po-218,
Po-214, Rn-220, Po-216 and Po-212 were derived. The measurements of the
contamination levels, their concentration gradients with the crystal growth
axis, and the uniformity among different crystal samples, are reported. The
radiopurity in the U-238 and Th-232 series are comparable to those of the best
reported in other crystal scintillators. Significant improvements in
measurement sensitivities were achieved, similar to those from dedicated
massive liquid scintillator detector. This analysis also provides in situ
measurements of the detector performance parameters, such as spatial
resolution, quenching factors, and data acquisition dead time.


title:
Nuclear k_T in d+Au Collisions from Multiparticle Jet Reconstruction at
  STAR

abstract:
  This paper presents the most recent nuclear k_T measurements from STAR
derived from multiparticle jet reconstruction of d+Au and p+p collisions at
sqrt(s)=200 GeV. Since jets reconstructed from multiple particles are
relatively free of fragmentation biases, nuclear k_T can be measured with
greater certainty in this way than with traditional di-hadron correlations.
Multi-particle jet reconstruction can also be used for a direct measurement of
the fragmentation function.


title:
Proton-lambda correlations in central Au+Au collisions at sqrt
  (s_NN)=200 GeV

abstract:
  We report on p-Lambda, p-Lambda bar, p bar-Lambda and p bar-Lambda bar
correlation functions constructed in central Au-Au collisions at
sqrt(s_NN)=200GeV by the STAR experiment at RHIC. The proton and lambda source
size is inferred from the p-Lambda and p bar-Lambda bar correlation functions.
They are found to be smaller than the pion source size also measured by the
STAR detector. This could be a consequence of the collision fireball's
collective expansion. The p-Lambda bar and p bar-Lambda correlations, which are
measured for the first time, exhibit a large anti-correlation. Annihilation
channels and/or a negative real part of the spin-averaged scattering length
must be included in the final-state interactions calculation to reproduce the
measured correlation function.


title:
Measurements of the nuclear modification factor and elliptic flow of
  $\phi$ mesons at RHIC

abstract:
  The observation of meson and baryon grouping in the $R_{CP}$ and $v_2$
measurements at intermediate $p_T$ has been interpreted as a manifestation of
bulk partonic matter hadronization through multi-parton dynamics such as
recombination of partons. $\phi$ mesons provide unique sensitivity to test
these theoretical scenarios, since the $\phi$ has a mass heavier than the
proton and close to the hyperons. The $R_{CP}$ and $v_2$ measurements of $\phi$
mesons from Run IV Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV at STAR are
presented. Energy and colliding system dependence of the $\phi$ yields at
mid-rapidity are discussed. The results are compared to the measurements of
other hadrons. Properties of strange quarks in the bulk matter at hadron
formation are discussed.


title:
Centrality dependence of heavy flavor production from single electron
  measurement

abstract:
  We present preliminary measurements of electron production in p+p, d+Au, and
Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV for transverse momenta 1.5 GeV/$c$
$<p_T<$8 GeV/$c$ as a function of centrality. These measurements were carried
out using the STAR Time Projection Chamber and Barrel Electromagnetic
Calorimeter. In this manuscript we describe the measurement techniques used to
discriminate electrons from hadrons and the method used to evaluate the
non-photonic contributions from semi-leptonic decays of heavy flavor mesons.
The observed nuclear modification factors, $R_{AA}$, of non-photonic electrons
indicate at substantial energy loss of heavy quarks at moderate to high $p_T$.


title:
Strange Particle Production Mechanisms in Proton-Proton Collisions at
  RHIC

abstract:
  We present data on strange particle production in elementary proton-proton
collisions at RHIC energies. Comparison to leading order and next-to-leading
order (NLO) calculations shows that the fragmentation process is flavor
dependent and that higherorder corrections are needed to describe all spectra,
in particular at these collision energies, which are modest compared to the
Tevatron energies. A model (EPOS) which takes into account multiple scattering
between projectile constituents seems to describe the data best.


title:
Accurate mass measurements of $^{26}$Ne, $^{26-30}$Na, $^{29-33}$Mg
  performed with the {\sc Mistral} spectrometer

abstract:
  The minuteness of the nuclear binding energy requires that mass measurements
be highly precise and accurate. Here we report on new measurements $^{29-33}$Mg
and $^{26}$Na performed with the {\sc Mistral} mass spectrometer at {\sc
Cern}'s {\sc Isolde} facility. Since mass measurements are prone to systematic
errors, considerable effort has been devoted to their evaluation and
elimination in order to achieve accuracy and not only precision. We have
therefore conducted a campaign of measurements for calibration and error
evaluation. As a result, we now have a satisfactory description of the {\sc
Mistral} calibration laws and error budget. We have applied our new
understanding to previous measurements of $^{26}$Ne, $^{26-30}$Na and
$^{29,32}$Mg for which re-evaluated values are reported.
