Application of the renormalization group to decay of the false vacuum

Technical Report:

Abstract

A renormalization group equation for the effective action of a massive scalar field theory is derived. It significantly restricts the dependence of the probability of decay of the false vacuum on the physical parameters. It is also remarkably useful for the implementation of a certain approximation of finite-temperature effects. Within this approximation one finds m{sub t} approx. 165 Gev if SU(2) x U(1) is broken by barrier penetration and the transition occurs when the probability is maximum. (author). 11 refs.
