Dr Amaresh Jaiswal (GSI Helmholtzzentrum für Schwerionenforschung)07/10/2015, 09:00Collective Phenomena in High Energy CollisionsOral PresentationUsing a viscosity-based survival scale for geometrical perturbations formed in the early stages of relativistic heavy-ion collisions, we model the radial flow velocity during freeze-out. Subsequently, we employ the Cooper-Frye freeze-out prescription, with first-order viscous corrections to the distribution function, to obtain the transverse momentum distribution of particle yields and flow...Go to contribution page

Dr Rafael Derradi de Souza (State University of Campinas - Brazil)07/10/2015, 09:20Collective Phenomena in High Energy CollisionsOral PresentationThe measurement of identified particle production rates as a function of event activity in small colliding systems has recently become of particular interest in understanding how observations performed in these systems relate to the much larger ones created in Pb-Pb collisions. Strangeness production may provide a valuable tool to probe changes in particle production mechanisms. We report on...Go to contribution page

Mr Emil Kaptur (University of Silesia)07/10/2015, 09:40Collective Phenomena in High Energy CollisionsOral PresentationThe aim of the NA61/SHINE ion programme is to explore the phase diagram of strongly interacting matter. The main physics goals are the study of the onset of deconfinement and the search for the critical point of strongly interacting matter. These goals are pursued by performing an beam momentum (13A - 158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan. This contribution...Go to contribution page

Prof. Byungsik Hong (Korea University)07/10/2015, 10:00Collective Phenomena in High Energy CollisionsOral PresentationQuarkonium has been regarded as one of the golden probes for the deconfined phase transition to the quark-gluon plasma (QGP) since late 80's when the relativistic heavy-ion experiments started at AGS and SPS. The heavy quarkonia can be generated in gluon-gluon scatterings at early stage of the collision as the large momentum transfer is required. Later the binding potential between a quark...Go to contribution page

Wojciech Florkowski (Institute of Nuclear Physics)07/10/2015, 10:20Collective Phenomena in High Energy CollisionsOral PresentationFor the first time we investigate non-equilibrium dynamic properties of a plasma consisting of confining gluons resulting from Gribov quantization [1]. For this purpose we employ the infrared-improved Gribov dispersion relation of gluons in the kinetic theory setup in the relaxation time approximation and determine the exact in- and out-of-equilibrium evolution of the system. In the static...Go to contribution page

Zhenyu Chen (CMS)07/10/2015, 11:10Collective Phenomena in High Energy CollisionsOral PresentationNew results of two- and multi-particle correlations in pp and pPb collisions will be presented. The measurements are performed as a function of multiplicity. In very-high-multiplicity events, a long-range near-side two-particle correlation is observed. Azimuthal anisotropy harmonics (v_n) are extracted as a function of eta, pT and multiplicity, using two- and multi-particle correlations....Go to contribution page

Laure Marie Massacrier (Orsay-LAL)07/10/2015, 11:30Collective Phenomena in High Energy CollisionsOral PresentationProton-lead and lead-proton data taking during 2013 has allowed LHCb to expand its physics program to heavy ion physics. Results include the first forward measurement of Z production in proton-lead collisions as well as a measurement of the nuclear modification factor and forward-backward production of prompt and displaced J/psis, Psi(2S) and Upsilons. Angular particle correlations have...Go to contribution page

Prof. L Gutay (Purdue University)07/10/2015, 11:50Collective Phenomena in High Energy CollisionsOral PresentationIt is shown that de-confinement can be achieved in high multiplicity non jet $\bar{p}p$ collisions at $\sqrt{s}$= 1.8 TeV Fermi National Accelerator Laboratory(FNAL- E735) experiment. In this paper we use the same data but analyze the transverse momentum spectrum in the framework of the clustering of color sources. This frame-work naturally predicts the reduction in the charged particle...Go to contribution page

Prof. Thomas Trainor (University of Washington)07/10/2015, 12:10Collective Phenomena in High Energy CollisionsOral PresentationRecent observations of ridge-like structure in p-p and p-A angular correlations at the RHIC and LHC are interpreted to imply collective motion in smaller systems. It is argued that if correlations representing flows in A-A collisions appear in smaller systems collectivity must extend to the smaller systems. But the argument could be reversed to conclude that such structures appearing in A-A...Go to contribution page
