In particular we derive the O(1/N_f) 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.Invited talk at RG96, Dubna, Russia; 10 latex pages, one postscript figure, uses sprocl.styHigh Energy Physics - Theorytext
