High temperature ln(T) contributions in thermal field theory
Abstract
We calculate, to one-loop order, the ln (T) contributions of 3-point functions in the φ3 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.
