Description
Jet quenching provides tomographic information of the evolution of the QCD matter formed
in the ultra-relativistic heavy ion collisions.
Perturbative QCD calculation for the jet quenching requires the informations of both elastic and
inelastic scatterings. We study the heavy quark radiative
energy loss in a dynamically screened expanding QCD medium by incorporating the
off-equilibrium distribution function in the kinematics.
Viscous effects on the inelastic energy loss are explicitly incorporated via
viscous corrections to the bosonic and fermionic thermal distribution functions.
The non-ideal effect to the many-body interactions are also included
through the Hard Thermal Loop technique. The jet energy loss is
studied within relativistic viscous hydrodynamic evolution of matter.
In the boost invariant longitudinal expansion of the medium, the specific
flow direction gives rise to an anisotropy in the QCD plasma.
We explore the directional dependence of the radiative energy loss in
the expanding viscous QCD plasma. The results have direct implications on the
D meson spectra as well as on the nuclear modification factor.
