| Popis: | 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. Our numerical results are in good agreement with recent data from the LHC. Comment: 15 pages; 11 figures; v2 has new results at 8 TeV LHC energy, more details on scale variation, and calculations of PDF uncertainties; v3 has a new presentation of the figures and a comparison to LHC data |
