High temperature ln(T) contributions in thermal field theory
arXiv:hep-th/9701021 · doi:10.1103/PhysRevD.55.7808
Abstract
We calculate, to one-loop order, the ln (T) contributions of 3-point functions in the ϕ^3 and Yang-Mills theory at high temperature. We find that these terms are Lorentz invariant and have the same structure as the ultraviolet divergent contributions which occur at zero temperature. A simple argument, valid for all N-point Green functions, is given for this behavior.
