Query: Open heavy flavor in Pb+Pb collisions at sqrt(s)=2.76 TeV within a
  transport model   The space-time evolution of open heavy flavor is studied in Pb+Pb collisions
at sqrt(s)=2.76 TeV using 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
scatterings with a running coupling and a Debye screening which is matched by
comparing to hard thermal loop calculations. The lack of radiative processes in
the heavy flavor sector is accounted for by scaling the binary cross section
with a phenomenological factor K=3.5, which describes well the elliptic flow
v_2 and nuclear modification factor R_AA at RHIC. Within this framework we
calculate in a comprehensive study the v_2 and R_AA of all interesting open
heavy flavor particles at the LHC: electrons, muons, D mesons, and non-prompt
J/psi from B mesons. We compare to experimental data, where it is already
available, or make predictions. To do this accurately next-to-leading order
initial heavy quark distributions are employed which agree well with
proton-proton data of heavy flavor at sqrt(s)=7 TeV.
