60. The measurement of non-photonic electrons in STAR

Olga Hajkova (Czech Technical University in Prague)

Oral presentation

Due to their large masses, charm and bottom quarks, are mostly produced during the initial phase of collisions via gluon fusion. Non-photonic electrons (NPE) are mainly produced by semileptonic decays of D and B mesons, hence the study of NPE in hadron-hadron and ion-ion collisions provides the information about heavy quarks production as well as the medium properties. In order to interpret...

56. Measurement of electrons from Heavy Quarks at PHENIX (for PHENIX collaboration)

Sourav Tarafdar (Banaras Hindu University, Varanasi, India)

Oral presentation

Heavy quarks are one of the most valuable probes for the matter produced in relativistic heavy ion collisions at RHIC. PHENIX experiment being designed specifically to study leptons, so electrons from the decay of heavy quarks acts as one of the most important tools in PHENIX for measurement of heavy quarks. Measurements of electron spectra at mid rapidity region has been done by PHENIX in...

112. Heavy-flavour production in pp and AA collisions at the LHC

Marco Monteno (INFN Torino)

Oral presentation

A refined version of a multi-step calculation of heavy-flavour observables in pp and AA collisions has been developed, based on pQCD at NLO accuracy followed by parton shower evolution to describe heavy-quark production and on the relativistic Langevin equation to describe their stochastic evolution in the QCD plasma. Then, hadronization is modeled through an implementation of the available...

33. Open heavy flavor and J/psi at RHIC and LHC

Jan Uphoff (Goethe University Frankfurt)

31/05/2012, 15:00

Oral presentation

Heavy flavors are important probes to study the early phase of ultra-relativistic heavy ion collisions at RHIC and LHC. We present results on the production and space-time evolution of heavy quarks and J/psi in the quark gluon plasma within the partonic transport model Boltzmann Approach to MultiParton Scatterings (BAMPS). Heavy quarks interact with the medium via binary and radiative...

117. Measurement of the nuclear modification factor of electrons from heavy-flavour decays in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV with ALICE

MinJung Kweon (University of Heidelberg)

31/05/2012, 15:20

Oral presentation

The medium-induced parton energy loss is expected to depend on its mass and colour charge. At the LHC, heavy quarks are copiously produced. This allows us to provide new constraints on partonic energy loss mechanisms in the medium produced in the heavy-ion collisions. The yield of electrons from semileptonic heavy-flavour decays has been measured at mid-rapidity \mbox{($|y| < 0.8$)} in Pb-Pb...

8. Toward a Complete Description of Heavy Flavor Transport in Medium

Mr Min He (Cyclotron Institute, Texas A&amp;M University)

31/05/2012, 15:40

Oral presentation

We evaluate heavy-flavor (HF) transport in relativistic heavy ion collisions within a nonperturbative (strong-coupling) framework. In the Quark-Gluon Plasma, heavy-quark diffusion coefficients are obtained from a potential-based T-matrix approach, which builds up resonance correlations toward the phase transition region. Those resonance correlations are also utilized for hadronizing heavy...
