Status of jet cross sections to NNLO
arXiv:hep-ph/0606301 · doi:10.1016/j.nuclphysbps.2006.09.038
Abstract
I review the state-of-the-art for fully differential numerical NNLO programs. Topics which are covered include the calculation of two-loop amplitudes, multiple polylogarithms, cancellation of infra-red divergences at NNLO and the efficient generation of the phase space. Numerical results for e+ e- --> 2 jets are also discussed.
