Calculatin of betaFunctions Up to TwoLoop Order in phi(4) TheoryBased on Stochastic Quantization Method
Abstract
On the basis of the renormalization scheme of the stochasticquantization method, two betafunctions 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 twoloop order.
