Radiative Quark p-Broadening in a Quark–Gluon Plasma beyond the Soft Gluon Approximation

Abstract

We study the radiative correction to p-broadening of a fast quark in a quark–gluon plasma beyond the soft gluon approximation. We find that the radiative processes can suppress considerably p-broadening. This differs dramatically from previous calculations to logarithmic accuracy in the soft gluon approximation, predicting a considerable enhancement of p-broadening.
