Antenna subtraction at NNLO with hadronic initial states: initial-final configurations

Daleo, A; Gehrmann-De Ridder, A; Gehrmann, T; Luisoni, G (2010). Antenna subtraction at NNLO with hadronic initial states: initial-final configurations. Journal of High Energy Physics, (1):118.

Abstract

We extend the antenna subtraction method to include initial states containing one hadron at NNLO. We present results for all the necessary subtraction terms, antenna functions, for the master integrals required to integrate them over the relevant phase space and finally for the integrated antennae themselves. Where applicable, our results are cross-checked against the known NNLO coefficient functions for deep inelastic scattering processes.
