Fast partons as a source of energy and momentum in a perturbative quark-gluon plasma

Abstract

I derive the space-time distribution of energy and momentum deposited by a fast parton traversing a perturbative quark-gluon plasma by considering the fast parton as the source of an external color field interacting with the medium. I include the medium's response to screen the fast parton's color field by incorporating dielectric functions and compare to the unscreened result.

As accepted for publication in Phys Rev D. Introduction is significantly expanded, some corrections made
