Operator Coefficients for Composite Operators in the $({\varphi }^4{)}_4$ Theory

Abstract

In a previous paper we derived a relation between the operator product coefficients and anomalous dimensions. We explore this relation in the $({\varphi }^4{)}_4$ theory and compute the coefficient functions in the products of ${\varphi }^2$ and ${\varphi }^4$ to first order in the parameter $\lambda$. The calculation results in two-loop beta functions.
