  1. 490. Investigations of anisotropic collectivity using multi-particle correlations in pp, p-Pb and Pb-Pb collisions with ALICE

    Oral

    Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of the Quark-Gluon Plasma created in Pb-Pb collisions.

    Recently, the results obtained for multi-particle correlations has been interpreted as evidence for collectivity in the small pp and p-Pb collision systems providing new insights into the systems' fluctuating initial conditions.

    Correlations and Fluctuations
    Oral

    The recent BES data of the energy dependent κσ^2 for net protons in Au+Au collisions presented large deviations from the statistical baselines at lower collision energies, and non-monotonic behavior at around 20 GeV, which indicates possible signals for the existence of the QCD critical point [1].

    In our recent paper [2], we introduce a freeze-out scheme to the dynamical models near the...

    Correlations and Fluctuations
    Oral

    We study elliptic and triangular flow and their dependence on rapidity using 3+1D hydrodynamic simulations with initial conditions (Nexus) that contain realistic fluctuations in all 3 dimensions. We compare to experimental data from STAR and find that long range, two particle $v_3$ correlations agree reasonably well with measurements. We find that an apparent decrease of $v_3$ with...

  4. 283. Hydrodynamic fluctuations in Pb+Pb collisions at LHC

    Correlations and Fluctuations
    Oral

    Fluctuations have been playing an important role in understanding observables
    in high-energy nuclear collisions.
    It is well known that
    higher harmonics of azimuthal angle distribution, for example, can be attributed to
    initial fluctuations of transverse profile from event to event.
    In this presentation, we focus on thermal fluctuations
    during hydrodynamic evolution of the system in the...

  5. 101. Jet evolution in a dense medium: event-by-event fluctuations and multi-particle correlations

    Jets and High pT Hadrons
    Oral

    We study the gluon distribution produced via successive medium-induced branchings
    by an energetic jet propagating through a weakly-coupled quark-gluon plasma. We show that
    under suitable approximations, the jet evolution is a Markovian stochastic process,
    which is exactly solvable. For this process, we construct exact analytic solutions
    for all the n-point correlation functions...
