Abstract

Abstract We present some analytical results on the question of symmetry restoration at finite temperature. The renormalization group improved one-loop effective potential is re-examined in a region where it is real and where it is a reliable approximation. We treat the soluable large- N limit of the O ( N) nonlinear sigma model and finally give some estimates of effects for the fundamental SU(2) Higgs model obtained in a mean field treatment.
