摘要：
We present results for W-boson production at large transverse momentum at LHC and Tevatron energies. We calculate complete next-to-leading-order QCD corrections and higher-order soft-gluon corrections to the differential cross section. The soft-gluon contributions are resummed at next-to-next-(t)o-leading-logarithm accuracy via the two-loop soft anomalous dimensions. Both next-to-leading-order and approximate next-to-next-to-leading-order p(T) distributions are presented. Our numerical results are in good agreement with recent data from the LHC.
