Massive particle production to NNLO in QCD
arXiv:0807.0976 · doi:10.1016/j.nuclphysbps.2008.09.086
Abstract
We discuss the recent derivation of the one-loop squared virtual QCD corrections to the W boson pair production in the quark-anti-quark-annihilation channel in the limit where all kinematical invariants are large compared to the mass of the W boson. In particular, we elaborate on the combined use of the helicity matrix formalism with the Mellin-Barnes representations technique.
