Renormalization group functions of QCD in large Nf
Abstract
We review the application of the critical point large Nf self-consistency method to QCD. In particular we derive the O(1/Nf) d-dimensional critical exponents whose epsilon-expansion determines the perturbative coefficients in MSbar of the field dimensions, beta-function and various twist-2 operators which occur in the operator product expansion of deep inelastic scattering.
