Renormalization group functions of QCD in large N_f
Abstract
We review the application of the critical point large N_f selfconsistency method to QCD. In particular we derive the O(1/N_f) ddimensional critical exponents whose epsilonexpansion determines the perturbative coefficients in MSbar of the field dimensions, betafunction and various twist2 operators which occur in the operator product expansion of deep inelastic scattering.
