Coherent Radiative Parton Energy Loss beyond the BDMPS-Z Limit    [PDF]

Korinna C. Zapp, Urs A. Wiedemann
It is widely accepted that a phenomenologically viable theory of jet
quenching for heavy ion collisions requires the understanding of medium-induced
parton energy loss beyond the limit of eikonal kinematics formulated by
Baier-Dokshitzer-Mueller-Peigne-Schiff and Zakharov (BDMPS-Z). Here, we
supplement a recently developed exact Monte Carlo implementation of the BDMPS-Z
formalism with elementary physical requirements including exact energy-momentum
conservation, a refined formulation of jet-medium interactions and a treatment
of all parton branchings on the same footing. We document the changes induced
by these physical requirements and we describe their kinematic origin.
