Some Two-Loop Corrections to the Finite Temperature Effective Potential in the Electroweak Theory

, 1992
Perturbation theory at finite temperature suffers from well-known infrared problems. In the standard model, as a result, one cannot calculate the effective potential for arbitrarily small values of $\phi$, the Higgs expectation value.
