NNLO Soft-gluon Corrections for the Z-boson and W-boson Transverse Momentum Distributions

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