Effect of Scheme Transformations on a Beta Function with Vanishing One-Loop Term

High Energy Physics - Theory 2020-09-16 v1

Abstract

It is commonly stated that because terms in the beta function of a theory at the level of 3\ell \ge 3 loops and higher are scheme-dependent, it is possible to define scheme transformations that can be used to remove these terms, at least in the vicinity of zero coupling. We prove that this is not, in general, possible in the situation where a beta function is not identically zero but has a vanishing one-loop term.
