Oral presentation

The production of the prompt charm mesons D0, D+, D∗+, and their antiparticles, in Pb–Pb collisions at the LHC, at a centre-of-mass energy sqrt(sNN) = 2.76 TeV per nucleon–nucleon collision, has been measured with the ALICE detector. The pt-differential production yields in the range 2 < pt < 16 GeV/c at central rapidity, |y| < 0.5, were used to calculate the nuclear modification factor RAA...

Oral presentation

Heavy quarks are a unique probe to study the medium produced in ultra-relativistic heavy ion collisions. The dominant process of charm quark production at RHIC is believed to be initial gluon fusion which can be calculated in the perturbative QCD. The upper limit of FONLL calculation seems to be in good agreement with charm cross section measurements at mid-rapidity in $p+p$ collisions at...

135. Heavy flavor suppression: an interplay of electric and magnetic mass effects

Oral presentation

Reliable predictions for jet quenching in ultra-relativistic heavy ion collisions require accurate computation of radiative energy loss. While all available energy loss calculations assume zero magnetic mass – in accordance with the one-loop perturbative calculations – different non-perturbative approaches report a non-zero magnetic mass at RHIC and LHC. We generalized the dynamical energy...

89. Open-charm meson elliptic flow measurement in Pb-Pb collisions at √sNN = 2.76 TeV with ALICE at the LHC.

Giacomo Ortona (INFN Torino)

Oral presentation

A Large Ion Collider Experiment (ALICE) is one of the four major experiments at the Large Hadron Collider (LHC), and it is dedicated to the study of ultra-relativistic heavy ion collisions, with the goal of investigating the properties of the high-density state of QCD matter produced in these collisions. The study of D meson production azimuthal anisotropy and the measurement of their...

132. Recent results on heavy quark quenching in ultrarelativistic heavy ions collisions: the effect of gluon damping

Pol Bernard Gossiaux (Subatech)

Oral presentation

Recently, we have proposed a microscopic approach for the quenching and thermalisation of heavy quarks (HQ) in URHIC [1, 2, 3], 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 hydrodynamical evolution of the hot...
