IR subtraction schemes: integrating the counterterms at NNLO in QCD

High Energy Physics - Phenomenology 2011-04-20 v2

Abstract

We briefly review a subtraction scheme for computing radiative corrections to QCD jet cross sections that can be defined at any order in perturbation theory. Hereafter we discuss the computational methods used to evaluate analytically and numerically the integrated counterterms arising from such a subtraction scheme. Basically these methods the Mellin-Barnes (MB) representations technique together with the harmonic summation and the sector decomposition.
