Somogyi, G; Trócsányi, Z (2008). A subtraction scheme for computing QCD jet cross sections at NNLO: integrating the subtraction terms I. Journal of High Energy Physics, (8):042.
In previous articles we outlined a subtraction scheme for regularizing doubly-real emission and real-virtual emission in next-to-next-to-leading order (NNLO) calculations of jet cross sections in electron-positron annihilation. In order to find the NNLO correction these subtraction terms have to be integrated over the factorized unresolved phase space and combined with the two-loop corrections. In this paper we perform the integration of all one-parton unresolved subtraction terms.
