The anomalous dimension of spin-1/2 baryons in many flavors QCD

Abstract

The anomalous dimension of spin-1/2 baryon operators in QCD is derived at leading 1/Nf order using the minimal subtraction scheme. A residual ambiguity, originating from the presence of evanescent operators in dimensional regularization, is parametrized by a function of the renormalized coupling. Our result is shown to agree with previous 2 and 3 loop calculations performed in two different renormalization schemes.

We briefly discuss the absence of scheme-dependence in physical observables to all orders in αNf and comment on the value of the anomalous dimension within the conformal window
