  1. 235. Studies of the nuclear stopping power in PbPb collisions at 2.76 TeV with CMS
    Clemens Wohrmann (KIT - Karlsruhe Institute of Technology (DE))

    Pre-equilibrium and initial state dynamics
    Oral Presentation
    The energy flow at very high pseudorapidity in PbPb collisions is sensitive to the very low-x components of the nuclear wave-function. The CASTOR calorimeter extends the pseudorapidity coverage of CMS to -6.6, which is only 1.4 units away from the beam rapidity. A comparison of the centrality dependence of forward energy flow to that at lower pseudorapidities can shed light on the gluon...

  2. 528. Highly-anisotropic hydrodynamics in 3+1 space-time dimensions and the early thermalization puzzle
    Michael Strickland (Gettysburg College), Wojciech Florkowski (Institute of nuclear Physics, Krakow)

    Oral Presentation
    Recently formulated model of highly-anisotropic and strongly dissipative hydrodynamics is used in 3+1 dimensions to study behavior of matter produced in ultra-relativistic heavy-ion collisions. We search for possible effects of the initial high anisotropy of pressure on the final soft-hadronic observables. We find that by appropriate adjustment of the initial energy density and/or the initial...

  3. 525. Azimuthal angular correlations in two-particle production in proton-nucleus collisions
    Jamal Jalilian-Marian (Baruch College)
    15/08/2012, 09:10
    Oral Presentation
    Di-hadron azimuthal angular correlations in the forward rapidity region of deuteron-nucleus collisions at RHIC show a disappearance of the away side peak with centrality and transverse momentum. This can be understood, in the Color Glass Condensate (CGC) formalism, to be due to multi-gluon exchanges between the projectile and target. We show that CGC formalism predicts a similar disappearance...

  4. 343. Cold Nuclear Matter Effects in 200 GeV d+Au Collisions at PHENIX
    Baldo Sahlmueller
    15/08/2012, 09:30
    Oral Presentation
    While the study of the quark-gluon plasma has been the primary focus of the RHIC experiments, much work has also been done to understand so-called cold nuclear matter (CNM) effects through $d$+Au collisions where no hot plasma is produced. Effects such as nuclear shadowing, Cronin enhancement, and initial-state parton energy loss, among others, are not only interesting in their own right, but...

  5. 87. Jet probes of cold and hot QCD matter
    Prof. Ben-Wei Zhang (Central China Normal University)
    15/08/2012, 09:50
    Jets
    Oral Presentation
    Parton energy loss in the hot QCD medium will manifest itself not only in leading hadron spectra but also in reconstructed jet productions in high-energy nucleus-nucleus collisions. With its more differential power full jets in heavy-ion collisions can then provide excellent tools to study the properties of the QGP and impose constraints on different parton energy loss models. With this...

  6. 609. Gravitational collapse and holographic thermalization
    Paul Chesler (MIT)
    15/08/2012, 10:10
    Oral Presentation
    A remarkable result from heavy ion collisions at the Relativistic Heavy Ion Collider and Large Hadron Collider is that, shortly after the collision event, the quark-gluon plasma produced behaves as a nearly ideal liquid. Understanding the dynamics responsible for such rapid "hydroization" is a challenge using traditional perturbative field theory. In recent years holography has emerged as...
