Abstract

The collisional energy gain of a heavy quark due to chromoelectromagnetic field fluctuations in a quark-gluon plasma is investigated. The field fluctuations lead to an energy gain of the quark for all velocities. The net effect is a reduction of the collisional energy loss by 15--40% for parameters relevant at RHIC energies.
