Space and time like cut vertices in QCD beyond the leading order - non-singlet sector

Abstract

In the framework of the cut vertex formalism we present the results of calculations of the quantities needed for a next to leading logarithmic analysis of scaling violations for structure and fragmentation functions in Quantum Chromodynamics. We find that an analytic continuation relation holds, between the time and space like regions, while the Gribov-Lipatov reciprocity relation is violated.
