Dr Min He (Hunan University,China)16/11/2012, 09:00We compute open heavy-flavor (HF) transport in relativistic heavy-ion collisions by combining a strong-coupling treatment in both macro- and microscopic dynamics (hydro and nonperturbative diffusion interactions) [1]. The hydrodynamic bulk evolution is quantitatively constrained by bulk and multi-strange hadron spectra and elliptic flow [2]. In the Quark-Gluon Plasma (QGP) phase, heavy-quark...Go to contribution page

Antoni Szczurek (I)16/11/2012, 09:30HF decays leptonsWe discuss charm production at LHC. The production of single $c \bar c$ pairs is calculated in the $k_t$-factorization approach. We use several unintegrated gluon distributions from the literature. Some of them include effect of small-$x$ staturation and fullfil Balitsky-Kovchegov evolution equation. The hadronization is included with the help of fragmentation functions found for the...Go to contribution page

Thierry Gousset (Subatech)16/11/2012, 10:00The effect of the damping of radiation in an absorptive medium on radiative energy loss is considered. First, the radiation spectrum for a fast parton going through a dense medium is estimated from considerations on the formation time in the QCD context. In a second stage, such a derivation is connected to a full calculation carried out in electrodynamics.Go to contribution page

Tomas Aronsson (Yale University (US))16/11/2012, 11:00Tomas Aronsson for the ALICE collaboration High-energy heavy-ion collisions at the LHC allow for the study of the properties of the quark-gluon plasma (QGP). Heavy quarks, charm and bottom, produced in the initial hard scattering processes of the collision are excellent probes of the QGP. When heavy quarks traverse the QGP they are expected to lose energy and such energy loss is predicted...Go to contribution page

Bogdan Theodor Rascanu (Johann-Wolfgang-Goethe Univ. (DE))16/11/2012, 11:30Theodor Rascanu for the ALICE collaboration In heavy-ion collisions, charm and beauty quarks are produced in the initial hard scattering processes. They propagate then through the created Quark Gluon Plasma. Therefore they are a sensitive tool to probe the medium's properties. One way to measure heavy-quarks is via electrons from the semileptonic decay channels of open charm and beauty...Go to contribution page

Dr Philippe Pillot (Laboratoire de Physique Subatomique et des Technologies Associees)16/11/2012, 12:00Heavy flavours (charm and beauty) are expected to provide essential information on the properties of the high-density strongly-interacting system formed in the early stages of high-energy heavy-ion collisions. In particular, the investigation of modifications of heavy-flavour transverse momentum yield will shed light on the nature of the parton-medium interactions, while the measurement of...Go to contribution page

Mariusz Przybycien (AGH Univesity of Science and Technology (PL))16/11/2012, 14:00Bottom quarks are important probes to study the hot, dense medium produced in the heavy ion collisions. These heavier quarks are produced at a relatively early stage of the nucleus-nucleus collisions and may have reduced gluon radiation due to the suppression of small angle gluon radiation known as the `dead cone effect’. Because of the heavy mass of b-hadrons, muons from semi-leptonic...Go to contribution page

Ryohji Akimoto (University of Tokyo)16/11/2012, 14:30Heavy quark (charm and bottom) is a good probe to study the interaction between partons and quark gluon plasma (QGP). Heavy quarks are created mainly by initial hard scatterings and interaction between heavy quarks and QGP during full space-time evolution is clearly reflected in the final states. A silicon vertex tracker (VTX) was installed at the PHENIX detector in 2011. The VTX enables us...Go to contribution page

Mustafa Mustafa (Purdue University)16/11/2012, 15:00Heavy quarks are produced early in the heavy-ion collisions and are expected to interact with the created strongly interacting partonic medium differently from light quarks. Therefore, they can shed new light on understanding the medium's properties. Simultaneous measurements of spectra and azimuthal anisotropy of electrons from semileptonic decays of heavy flavor hadrons provide...Go to contribution page

Pol Gossiaux (Subatech)16/11/2012, 15:30HF decays leptonsRecently, we have proposed a microscopic approach for the quenching and thermalisation of heavy quarks (HQ) in URHIC \cite{Gossiaux:2008,Gossiaux:2009,Gossiaux:2010}, assuming that they interact with light partons through both elastic and radiative processes evaluated by resorting to some parameterization of the running coupling constant, while those partons are spatially distributed along...Go to contribution page
