1201.5265 (Nikolaos Kidonakis et al.)

Higher-order QCD corrections for the W-boson transverse momentum
distribution
   [PDF]

Nikolaos Kidonakis, Richard J. Gonsalves
We present results for W-boson production at large transverse momentum at LHC
and Tevatron energies. We calculate complete next-to-leading-order (NLO) QCD
corrections and higher-order soft-gluon corrections to the differential cross
section. The soft-gluon contributions are resummed at
next-to-next-to-leading-logarithm (NNLL) accuracy via the two-loop soft
anomalous dimensions. Both NLO and approximate next-to-next-to-leading-order
(NNLO) p_T distributions are presented.
