Calculatin of beta-Functions Up to Two-Loop Order in phi(4) TheoryBased on Stochastic Quantization Method
Abstract
On the basis of the renormalization scheme of the stochasticquantization method, two beta-functions in phi(4) theory,beta_{lambda} and beta_{gamma} which govern the scalingbehaviors of the coupling constant lambda and the fictitious time,respectively, are calculated up to the two-loop order.
