Open heavy flavor in ultra-relativistic heavy ion collisions — •Jan Uphoff1, Oliver Fochler1, Zhe Xu2, and Carsten Greiner1 — 1Institut für Theoretische Physik, Goethe-Universität Frankfurt, Max-von-Laue-Straße 1, D-60438 Frankfurt, Germany — 2Department of Physics, Tsinghua University, Beijing, China
The production and space-time evolution of heavy quarks in the quark
gluon plasma is studied within the partonic transport model Boltzmann
Approach to MultiParton Scatterings (BAMPS). An updated version of
BAMPS is presented which allows interactions among all partons:
gluons, light quarks and heavy quarks. Heavy quarks, in particular,
interact with the rest of the medium via binary and radiative
scatterings with a running coupling and a more precise Debye screening
which is derived from hard thermal loop calculations. We compare our
results of the elliptic flow and nuclear modification factor not only
to experimental data of heavy flavor electrons and D mesons at RHIC,
but also to LHC data of heavy flavor electrons, muons, D mesons, and
non-prompt J/psi. The latter two are in particular sensitive to the
mass difference of charm and bottom quarks.
