Abstract
In this proceedings, I consider two-loop contributions to real photon production in thermal QCD. If the photon is strictly massless, strong collinear divergences appear in this calculation. These singularities are regularized by the quark thermal mass of order , which generates powers of , so that the corresponding terms are strongly enhanced with respect to naive expectations of their order of magnitude.
