High Energy Physics - Theory 2014-11-18 v1

Abstract

A Rayleigh-Schr\"{o}dinger perturbation theory based on the Gaussian wavefunctional is constructed. The method can be used for calculating the energies of both the vacuum and the excited states. A model calculation is carried out for the vacuum state of the λϕ4\lambda\phi^4 field theory.
