  1. 87. The stringness of heavy ion collisions
    Jorge Casalderrey Solana (University of Barcelona (ES))

  2. 69. Renormalization of the jet-quenching parameter
    Dr Yacine Mehtar-Tani (IPhT)

    Jets in the vacuum and in the medium
    Theory
    In the context of the recently derived probabilistic picture of in-medium jet evolution, we study radiative corrections which yield potentially large double logarithms, $\alpha_s \ln^2 L$, for large enough medium length $L$.  We show in particular that, due to a large separation of time scales, these corrections can be reabsorbed in a renormalization of the quenching parameter in both the...

  3. 51. Production of strange particles in charged jets in Pb--Pb and p--Pb collisions measured with ALICE

    Jets in the vacuum and in the medium
    Experimental
    Properties of the hot and dense strongly interacting matter created in ultra-relativistic heavy-ion collisions can be studied using jets. Hadronisation processes occurring in jets are expected to be modified by the interaction of partons with the medium. At intermediate $p_\textrm{T}$, a~strong increase of the baryon-to-meson ratio is observed for inclusive light particles produced in...

  4. 53. From light- to heavy-quark fragmentation in jets: current measurements in pp collisions with the ALICE detector and perspectives
    Chiara Bianchin (University of Utrecht (NL))

    Jets in the vacuum and in the medium
    Experimental
    Measurements of jet fragmentation in heavy-ion collisions are important for investigating the medium-induced parton energy loss. Partons propagating in a dense and strongly interacting medium lose energy giving rise to a softening of the final hadron pT-differential spectrum. The presence of the strongly interacting medium may also lead to particle dependent modifications of the fragmentation...

  5. 77. Thermodynamic and transport properties of finite temperature and chemical potential strongly coupled quark gluon plasma
    Dr Hamza Berrehrah (FIAS)
    23/09/2014, 19:00
    QCD at high temperature/density and LQCD
    Theory
    The transport properties (shear and bulk viscosities, electric and heat conductivities, etc) of the strongly coupled quark gluon plasma (sQGP) are computed at finite temperature and chemical potential. The cross sections for quark ($q$), anti-quark ($\bar{q}$) and gluon ($g$) elastic scattering at finite temperature and chemical potential, used in our study, are evaluated for dynamical...

  6. 30. Heavy flavours in nucleus-nucleus collisions: quenching, flow and correlations
    Dr Andrea Beraudo (INFN (Torino))
    23/09/2014, 19:20
    Heavy flavor, dileptons and photons
    Theory
    We present results for the quenching, elliptic flow and azimuthal correlations of heavy flavours in high-energy nucleus-nucleus collisions obtained through the POWLANG transport setup, developed in the past to study the propagation of heavy quarks in the Quark-Gluon Plasma and here extended to include a modeling of their hadronization in the presence of a medium. Hadronization is described as...
