Higher Loop Corrections to the Infrared Evolution of Fermionic Gauge Theories in the RI' Scheme

Research output: Contribution to journalJournal articleResearchpeer-review

Abstract

We study the evolution of the gauge coupling and the anomalous dimension of the mass towards an infrared fixed point for non-supersymmetric gauge theories in the modified regularization invariant, RI', 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, $\bar{\text{MS}}$, scheme. Our results are of the same order when compared to the $\bar{\text{MS}}$ scheme.
