Elliptic flow and energy loss of heavy quarks in ultra-relativistic heavy ion collisions

Understand

The space-time propagation of heavy quarks in ultra-relativistic heavy ion collisions is studied within the partonic transport model Boltzmann Approach of MultiParton Scatterings (BAMPS).

• In this model heavy quarks interact with the partonic medium via binary scatterings.
• The cross sections for these interactions are calculated with leading order perturbative QCD, but feature a more precise Debye screening derived within the hard thermal loop approximation and obey the running of the coupling.
• Within this framework the elliptic flow and the nuclear modification factor of heavy quarks are computed for RHIC and LHC energies and compared to available experimental data.
