Abstract

We study the evolution of the gauge coupling and the anomalous dimension of the mass towards an infrared fixed point for nonsupersymmetric gauge theories in the modified regularization invariant scheme. This is done at the three-loop level where all the renormalization group functions have been calculated explicitly. The purpose is to assess the scheme dependence of earlier and similar investigations performed at three- and four-loop order in the modified minimal subtraction, MS¯, scheme. Our results are of the same order when compared to the MS¯ scheme.
