Description
In this work we have made an attempt to compute the collisional energy loss of heavy fermions and subsequently heavy quarks in a anisotropic and collisional quark gluon plasma. We have included anisotropy by following the Romatschke-Srickland construction of the distribution function where the non-equilibrium deformation is controlled by an anisotropy parameter. For the inclusion of collisions we have employed the Bhatnagar-Gross-Krook kernel with a collision rate, that describes how collisions equilibrate the system with time. We have computed the soft and hard contributions to the energy loss. The hard part contribution is computable via tree-level scattering. However, the soft contribution requires the resummed gluon propagator which we calculate via Hard Thermal Loop perturbation theory.
