Query: Charm energy loss and D-D correlations from a shower picture   Measurements of mesons containing charm or bottom quarks at high transverse
momentum (P_T) constitute an interesting set of probes for the nature of the
interaction of hard partons with a QCD medium as created in ultrarelativistic
heavy-ion (A-A) collisions. Not only can D and B mesons to a reasonable
accuracy be assumed to represent the hadronization of a b or c quark after
passage through the medium, i.e. they explicitly reflect quark-medium
interaction, but also their interaction physics is expected to be different
from light partons traversing a medium: The quark mass restricts radiation
phase space, leading to a reduction of both vacuum and medium induced
radiation, a phenomenon known as the 'dead cone effect'. Due to this difference
in physics, heavy quark interaction with the medium is usually treated in the
leading parton energy loss approximation, whereas the theory of light parton
physics has moved to modeling the full medium-modified shower evolution. In
this work, an attempt is made to create a more unified description of light
parton and heavy quark physics at high P_T by computing charm-medium
interactions in terms of the nuclear suppression factor and back-to-back
correlations using an in-medium shower evolution Monte Carlo (MC) code that is
well tested for light parton physics.
