Two-loop corrections to W and Z boson production at high pT
  We present new results for the complete two-loop corrections in the soft approximation for W and Z boson production at large transverse momentum. Analytical expressions for the NNLO approximate corrections are used to calculate transverse momentum distributions. Results for the W boson pT distribution at Tevatron and LHC energies are presented.
