To appear in the NN2012 Proceedings in Journal of Physics: Conference Series (JPCS) \\ The elliptic-flow ratio of neutrons with respect to protons in reactions of neutron rich heavy-ions systems at intermediate energies has been proposed as an observable sensitive to the strength of the symmetry term in the nuclear Equation Of State (EOS) at supra-saturation densities. The recent results obtained from the existing FOPI/LAND data for $^{197}$Au+$^{197}$Au collisions at 400 MeV/nucleon in comparison with the UrQMD model allowed a first estimate of the symmetry term of the EOS but suffer from a considerable statistical uncertainty. In order to obtain an improved data set for Au+Au collisions and to extend the study to other systems, a new experiment was carried out at the GSI laboratory by the ASY-EOS collaboration in May 2011. \\ ( http://arxiv.org/abs/1209.5961 , 7316kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1209.5405 (*cross-listing*) Date: Mon, 24 Sep 2012 20:05:40 GMT (69kb) Title: Heavy quark energy loss and thermalization in hot and dense nuclear matter Authors: Shanshan Cao, Guang-You Qin and Steffen A. Bass Categories: nucl-th nucl-ex Comments: 9 pages, 11 figures, talk given by Shanshan Cao at the 11th International Conference on Nucleus-Nucleus Collisions (NN2012), San Antonio, Texas, USA, May 27-June 1, 2012. To appear in the NN2012 Proceedings in Journal of Physics: Conference Series (JPCS) \\ We study heavy quark energy loss and thermalization in hot and dense nuclear medium. The diffusion of heavy quarks is calculated via a Langevin equation, both for a static medium as well as for a quark-gluon plasma (QGP) medium generated by a (3+1)-dimensional hydrodynamic model. We investigate how the initial configuration of the QGP and its properties affect the final state spectra and elliptic flow of heavy flavor mesons and non-photonic electrons. It is observed that both the geometric anisotropy of the initial profile and the flow profile of the hydrodynamic medium play important roles in the heavy quark energy loss process and the development of elliptic flow. Within our definition of the thermalization criterion and for reasonable values of the diffusion constant, we observe thermalization times that are longer than the lifetime of the QGP phase. \\ ( http://arxiv.org/abs/1209.5405 , 69kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5410 (*cross-listing*) Date: Mon, 24 Sep 2012 20:19:04 GMT (20kb) Title: Collisional vs. Radiative Energy Loss of Heavy Quark in a Hot and Dense Nuclear Matter Authors: Shanshan Cao, Guang-You Qin, Steffen A. Bass and Berndt M\"uller Categories: nucl-th hep-ph nucl-ex Comments: 4 pages, 6 figures, talk given by Shanshan Cao at Quark Matter 2012 \\ We study the heavy quark evolution in a quark-gluon plasma medium within the framework of Langevin equation coupled to a (2+1)-dimensional viscous hydrodynamic model. We modify the current Langevin algorithm such that apart from quasi-elastic scattering, medium-induced radiative energy loss is incorporated as well by treating gluon radiation as an extra force term. We find a significant effect of gluon radiation on heavy quark energy loss at LHC energies. Our calculation provides a good description of the D meson suppression measured by ALICE experiment, and makes a prediction for B meson suppression and flow. \\ ( http://arxiv.org/abs/1209.5410 , 20kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5636 (*cross-listing*) Date: Tue, 25 Sep 2012 15:02:34 GMT (270kb,D) Title: Heavy Flavour Measurements in pp and Pb--Pb Collisions with the ALICE Experiment at LHC Authors: Chiara Zampolli for the ALICE Collaboration Categories: hep-ex nucl-ex Comments: Proceedings of the conference: Primordial QCD Matter in LHC Era: Implications of LHC Results on the Early Universe - Cairo, 4-8 December 2011 \\ Heavy flavour is mainly produced during the initial hard partonic interactions in a heavy ion collision, and is well-suited to probe the early phases of the evolution of the system. This contribution will focus on Pb--Pb analyses at a centre-of-mass energy per nucleon pair of 2.76 TeV, with some hints at the $\pp$ data at 7 and 2.76 TeV. Results of open heavy flavour analyses will be shown for various decay channels, including electrons, muons, and hadronic charm decays, together with results obtained for heavy quarkonia at both central and forward rapidities. \\ ( http://arxiv.org/abs/1209.5636 , 270kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5637 (*cross-listing*) Date: Tue, 25 Sep 2012 15:03:25 GMT (4267kb,D) Title: Particle Identification with the ALICE detector at the LHC Authors: Chiara Zampolli for the ALICE Collaboartion Categories: hep-ex nucl-ex Comments: Proceeding of the Conference: Physics at LHC 2012, 3-9 June 2012 \\ ALICE is the LHC experiment dedicated to the study of Heavy-Ion collisions. Many observables related to the properties of the medium created in such collisions rely on the excellent capabilities of the detector in terms of Particle Identification (PID) of particles. In the following, the various PID techniques used for the different ALICE analyses will be described. Focus will be given to the detectors' performance, and selected results will be presented on pp data collected at sqrt(s) = 7 TeV and PbPb collisions at sqrt(s_NN) = 2.76 TeV. \\ ( http://arxiv.org/abs/1209.5637 , 4267kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5816 (*cross-listing*) Date: Wed, 26 Sep 2012 02:22:24 GMT (865kb,D) Title: Pairing at High Spin Authors: S.

(10 pages, 5 figures, 25 references) \\ The giant dipole resonance's (GDR) width and shape at finite temperature and angular momentum are described within the phonon damping model (PDM), which predicts an overall increase in the GDR's total width at low and moderate temperature T, and its saturation at high T. At T< 1 MeV the GDR width remains nearly constant because of thermal pairing. The PDM description is compared with the experimental systematics obtained from heavy-ion fusion, inelastic scattering of light particles on heavy targets, and alpha induced fusion reactions, as well as with predictions by other theoretical approaches. The results obtained within the PDM and GDR's experimental data are also employed to predict the viscosity of hot medium and heavy nuclei. \\ ( http://arxiv.org/abs/1209.5820 , 1440kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5856 (*cross-listing*) Date: Wed, 26 Sep 2012 07:51:44 GMT (2328kb) Title: Neutron imaging detector based on the muPIC micro-pixel chamber Authors: J.

The prototype system, with an active area of 10cm x 10cm and operated at a gas pressure of 2 atm, measures both the energy deposition (via time-over-threshold) and 3-dimensional track of each neutron-induced event, allowing the reconstruction of the neutron interaction point with improved accuracy. Using a simple position reconstruction algorithm, a spatial resolution of 349 +/- 36 microns was achieved, with further improvement expected. The detailed tracking allows strong rejection of background gamma-rays, resulting in an effective gamma sensitivity of 10^-12 or less, coupled with stable, robust neutron identification. The detector also features a time resolution of 0.6 microseconds. \\ ( http://arxiv.org/abs/1209.5856 , 2328kb) ------------------------------------------------------------------------------ \\ arXiv:1209.5936 (*cross-listing*) Date: Wed, 26 Sep 2012 13:39:03 GMT (587kb,D) Title: The Old New Frontier: Studying the CERN-SPS Energy Range with NA61/SHINE Authors: Marek Szuba, for the NA61/SHINE Collaboration Categories: hep-ex nucl-ex Comments: 8 pages, 6 figures. To be published in the proceedings of the International Conference on New Frontiers in Physics (ICFP) 2012 \\ With the Large Hadron Collider entering its third year of granting us insight into the highest collision energies to date, one should nevertheless keep in mind the unexplored physics potential of lower energies. A prime example here is the NA61/SHINE experiment at the CERN Super Proton Synchrotron. Using its large-acceptance hadronic spectrometer, SHINE aims to accomplish a number of physics goals: measuring spectra of identified hadrons in hadron-nucleus collisions to provide reference for accelerator neutrino experiments and cosmic-ray observatories, investigating particle properties in the large transverse-momentum range for hadron+hadron and hadron+nucleus collisions for studying the nuclear modification factor at SPS energies, and measuring hadronic observables in a particularly interesting region of the phase diagram of strongly-interacting matter to study the onset of deconfinement and search for the critical point of strongly-interacting matter with nucleus-nucleus collisions. This contribution shall summarise results obtained so far by NA61/SHINE, as well as present the current status and plans of its experimental programme. \\ ( http://arxiv.org/abs/1209.5936 , 587kb) ------------------------------------------------------------------------------ \\ arXiv:1209.6030 (*cross-listing*) Date: Wed, 26 Sep 2012 18:51:54 GMT (28kb) Title: Nuclear modification of high transverse momentum particle production in p+A collisions at RHIC and LHC Authors: Zhong-Bo Kang, Ivan Vitev, Hongxi Xing Categories: hep-ph hep-ex nucl-ex nucl-th Comments: 8 pages, 4 figures \\ We present results and predictions for the nuclear modification of the differential cross sections for inclusive light hadron and prompt photon production in minimum bias d+Au collisions at $\sqrt{s} = 200$ GeV and minimum bias p+Pb collisions at $\sqrt{s} = 5$ TeV at RHIC and LHC, respectively. Our calculations combine the leading order perturbative QCD formalism with cold nuclear matter effects that arise from the elastic, inelastic and coherent multiple scattering of partons in large nuclei. We find that a theoretical approach that includes the isospin effect, Cronin effect, cold nuclear matter energy loss and dynamical shadowing can describe the RHIC d+Au data rather well. The LHC p+Pb predictions will soon be confronted by new experimental results to help clarify the magnitude and origin of cold nuclear matter effects and facilitate precision dense QCD matter tomography. \\ ( http://arxiv.org/abs/1209.6030 , 28kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1112.5327 (*cross-listing*) replaced with revised version Tue, 25 Sep 2012 08:15:38 GMT (78kb) Title: The $K^- p \rightarrow \eta \Lambda$ reaction in an effective Lagrangian model Authors: Bo-Chao Liu and Ju-Jun Xie Categories: nucl-th hep-ph nucl-ex Comments: Published version Journal-ref: Phys.
