Infrared structure of e+e- 3 jets at NNLO - the CF2 contribution
Abstract
We discuss the infrared structure of e+e- -> 2 and 3 jets at NNLO in QCD perturbation theory and describe subtraction terms that render the separate parton-level contributions finite. As a first result, we find that the NNLO CF2 contribution to the first moment of the Thrust distribution <1-T> = -20.4 +/- 4.
