Subtraction method of computing QCD jet cross sections at NNLO accuracy


Trócsányi, Z; Somogyi, G (2008). Subtraction method of computing QCD jet cross sections at NNLO accuracy. Nuclear Physics B - Proceedings Supplements, 183:30-35.

Abstract

We present a general subtraction method for computing radiative corrections to QCD jet cross sections at next-to-next-to-leading order accuracy. The steps needed to set up this subtraction scheme are the same as those used in next-to-leading order computations. However, all steps need non-trivial modifications, which we implement such that that those can be defined at any order in perturbation theory. We give a status report of the implementation of the method to computing jet cross sections in electron-positron annihilation at the next-to-next-to-leading order accuracy.
