QCD and QED renormalization group functions - a large N_f approach
arXiv:hep-ph/9604426 · doi:10.1016/S0920-5632(96)90004-3
Abstract
The large N_f self-consistency programme is reviewed. As an application the QCD beta-function is computed at O(1/N_f) and the anomalous dimensions of polarized twist-2 singlet operators are determined at the same order.
