Naghmeh Mohammadi (Nikhef National institute for subatomic physics (NL))30/06/2016, 09:00Contributed TalkThe latest ALICE results on the centrality and transverse momentum dependence of $v_{2}$, $v_{3}$, $v_{4}$ and $v_{5}$ for $\pi^{\pm}$, $\mathrm{K}^{\pm}$ and p+$\overline{\mathrm{p}}$ in Pb-Pb collisions at $\sqrt{s_\mathrm{{NN}}} = 2.76$ TeV are presented. The values of these flow coefficients exhibit a clear mass ordering for $p_{\mathrm{T}} < 3$ $\mathrm{GeV}/c$ for all harmonics. For...Go to contribution page

Michael Lomnitz (Kent State University)30/06/2016, 09:20Contributed TalkDue to their large masses, heavy quarks are predominantly produced through initial hard scatterings in heavy-ion collisions. As such, they experience the entire evolution of the hot and dense medium created in such collisions and are expected to thermalize much more slowly than light flavor quarks. For instance, the azimuthal anisotropy of charm quarks with respect to the reaction plane over...Go to contribution page

Roli Esha (University of California - Los Angeles)30/06/2016, 09:40Contributed TalkHeavy quarks are considered as an important probe to understand the properties of the Quark Gluon Plasma (QGP) created in relativistic heavy ion collisions. These are produced on a short time scale in hard partonic scatterings during the early stages of the nucleus-nucleus collision. The probability of thermal production of heavy quark pairs in the high temperature phase of the plasma is...Go to contribution page

Hanlin Li (Purdue University, Wuhan University of Science and Technology)30/06/2016, 10:00Contributed TalkA Multi-Phase Transport (AMPT) model has been shown to describe experimental data well, such as the bulk properties of particle spectra and azimuthal anisotropies ($v_n$) in heavy ion collisions [1]. Recent studies show that AMPT describes the $v_n$ data in small system collisions as well [2]. We follow the parton cascading history in AMPT and find that the opacity in AMPT is relatively small...Go to contribution page

George Stephans (Massachusetts Inst. of Technology (US))30/06/2016, 10:20Contributed TalkObservation of a long-range, near-side, two-particle correlation (known as the “Ridge”) in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. CMS has excellent capabilities of reconstructing weakly decay strange hadrons such as $K^0_s$, $\Lambda$ and $\Xi^-$. Studies of strange hadron production and correlations in...Go to contribution page

Haojie Xu (Peking University)30/06/2016, 11:00Contributed TalkIn this talk, we present our recent investigations on the higher order flow harmonics in 2.76A TeV Pb+Pb collisions using the iEBE-VISHNU hybrid model. (1). Using iEBE-VISHNU model with AMPT initial conditions, we calculate the higher order flow harmonics of identified hadrons in 2.76A TeV Pb+Pb collisions. Our model calculations generally reproduce the recent ALICE data on higher order flow...Go to contribution page

ATLAS measurement of azimuthal correlations between particle pairs at large pseudorapidity separation in pp and pPb collisions are presented. The data were collected using a combination of the minimum-bias and high track-multiplicity triggers. A detailed study of the dependence of two-particle correlations on the charged particle multiplicity, transverse momentum of the pair constituents and...

You Zhou (Niels Bohr Institute (DK))30/06/2016, 11:40Contributed TalkAnisotropic flow is a sensitive probe of the initial conditions and the transport properties of the Quark Gluon Plasma (QGP) produced in heavy-ion collisions. In this talk, we present the first results of elliptic ($v_2$), triangular ($v_3$) and quadrangular flow ($v_4$) of charged particles in Pb-Pb collisions at $\sqrt{s_{_{\rm NN}}}=$ 5.02 TeV with the ALICE detector. An increase of...Go to contribution page

Jean-Yves Ollitrault (CNRS)30/06/2016, 12:00Contributed TalkThe ATLAS collaboration has accurately measured elliptic flow, $v_2$, using multi-particle cumulants [arxiv:1408.4342], and observed for the first time a slight difference between $v_2\{4\}$ and $v_2\{6\}$. If the fluctuations of $v_2$ were Gaussian, all cumulants would coincide beyond order 4 [arXiv:0708.0800] therefore this measurement shows that $v_2$ fluctuations are slightly non-Gaussian....Go to contribution page

Niseem Abdelrahman (Stony Brook University)30/06/2016, 12:20Contributed TalkWe present recent STAR measurements of the harmonic coefficients $v_{n}\{2\}$, with n$\leq$4, obtained for pseudorapidity separation $|\Delta\eta|>0.7$, for the full span of energies (7.7 - 200 GeV) in beam energy scan I (BES-I). The pT and centrality dependent measurements validate the acoustic scaling patterns expected for hydrodynamic-like expansion over the entire range of beam energies...Go to contribution page
