摘要：

We present results for the Z boson and W boson transverse momentum ( p(T)) distributions for large pT at LHC and Tevatron energies. We calculate complete next-to-leading-order QCD corrections as well as softgluon corrections at next-to-next-to-leading order (NNLO) to the differential cross section. The NNLO soft-gluon contributions are derived from next-to-next-to-leading-logarithm resummation at two loops. We find enhancements of the pT distributions and reductions of the scale dependence when the NNLO corrections are included.
