Radiative and Collisional Energy Loss of Heavy Quarks in Deconfined Matter
Abstract
We extend our recently advanced model on collisional energy loss of heavy quarks in a quark gluon plasma (QGP) by including radiative energy loss. We discuss the approach and present calculations for PbPb collisions at s=2.76 TeV. The transverse momentum spectra, RAA, and the elliptic flow v2 of heavy quarks have been obtained using the model of Kolb and Heinz for the hydrodynamical expansion of the plasma.
