  We present a study of higher order QCD corrections beyond NLO to processes
with an electroweak vector boson, W or Z, in association with jets. We focus on
the regions of high transverse momenta of commonly used differential
distributions. We employ the LoopSim method to merge NLO samples of different
multiplicity obtained from MCFM and from BLACKHAT+SHERPA in order to compute
the dominant part of the NNLO corrections for high-pT observables. We find that
these corrections are indeed substantial for a number of experimentally
relevant observables. For other observables, they lead to significant reduction
of scale uncertainties.
