Enhanced photon production rate on the light--cone
arXiv:hep-ph/9604398 · doi:10.1103/PhysRevD.54.5274
Abstract
Recent studies of the high temperature soft photon production rate on the light--cone using Braaten--Pisarski resummation techniques have found collinear divergences present. We show that there exist a class of terms outside the Braaten--Pisarski framework which, although also divergent, dominate over these previously considered terms. The divergences in these new terms may be alleviated by application of a recently developed resummation scheme for processes sensitive to the light--cone.
