Proof of a mass singularity free property in high temperature QCD
arXiv:hep-th/0301170 · doi:10.1063/1.1536255
Abstract
It is shown that three series of diagrams entering the calculation of some hot process, are mass (or collinear) singularity free, indeed. This generalizes a result which was recently established up to the third non trivial order of (thermal) Perturbation Theory.
