High temperature ln(T) contributions in thermal field theory
- Instituto de Fisica, Universidade de Sao Paulo, Sao Paulo, 05389-970 Sao Paulo (Brazil)
We calculate, to one-loop order, the ln(T) contributions of three-point functions in the {phi}{sup 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. {copyright} {ital 1997} {ital The American Physical Society}
