Transverse momentum broadening and gauge invariance

High Energy Physics - Phenomenology 2015-06-11 v1

Abstract

In the framework of the soft-collinear effective theory, we present a gauge invariant definition of the transverse momentum broadening probability of a highly-energetic collinear quark in a medium and consequently of the jet quenching parameter q^\hat{q}.
