On Connection between Coefficient Functions for Deep-Inelastic and Annihilation Processes
Abstract
It has been shown that the one-loop behavior of the axial anomaly, occurring when the axial current is appropriately normalized, leads to the cancellation of the corrections of type CFN αsN,~~ (N≥ 1) in the Crewther relation for the coefficient functions of deep-inelastic and annihilation processes. The arguments in favour of the overall factorization of the factor β( αs)/ αs in all orders of perturbation theory in this relation are presented.
