Abstract

The formulae useful for the calculation of the partonic cross sections in the next-to-leading order of perturbative expansion in massless QCD are given. In particular the renormalized vertex functions and propagators, the rules for the evaluating of “box” diagrams, and integrals over 2- and 3-particle phase-space are presented. Ultraviolet and infrared divergencies are dimensionally regularized and the MS renormalization scheme is adopted.
