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.
