Heavy-Quark Kinetics in the QGP at LHC

Abstract

We present predictions for the nuclear modification factor and elliptic flow of D and B mesons, as well as of their decay electrons, in semicentral Pb-Pb collisions at the LHC. Heavy quarks are propagated in a Quark-Gluon Plasma using a relativistic Langevin simulation with drag and diffusion coefficients from elastic interactions with light anti-/quarks and gluons, including non-perturbative resonance scattering. Hadronization at T_c is performed within a combined coalescence-fragmentation scheme.
