Vacuum Instability and Higgs Scalar Mass
Abstract
A procedure is given to estimate the decay probability of a metastable vacuum state in quantum field theory. As an application, in the WeinbergSalam model the lower bound (for θ_{W}=35°) on the Higgs mass can be reduced from 4.9 GeV, corresponding to effective stability of a metastable vacuum.
