NNLO Virtual corrections to W+ W- production at the LHC

Abstract

We report on a recent calculation of the two-loop 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. Our result is exact up to terms suppressed by powers of the W boson mass. The infrared pole structure is in agreement with the prediction of Catani's general formalism for the singularities of two-loop QCD amplitudes.
