Query: NLO+NLL limits on W' and Z' gauge boson masses in general extensions of
  the Standard Model   QCD resummation predictions for the production of charged (W') and neutral
(Z') heavy gauge bosons decaying leptonically are presented. The results of our
resummation code at next-to-leading order and next-to-leading logarithmic
(NLO+NLL) accuracy are compared to Monte Carlo predictions obtained with PYTHIA
at leading order (LO) supplemented with parton showers (PS) and FEWZ at NLO and
next-to-next-to-leading order (NNLO) for the $p_T$-differential and total cross
sections in the Sequential Standard Model (SSM) and general SU(2)xSU(2)xU(1)
models. The LO+PS Monte Carlo and NNLO fixed-order predictions are shown to
agree approximately with those at NLO+NLL at small and intermediate $p_T$,
respectively, and the importance of resummation for total cross sections is
shown to increase with the gauge boson mass. The theoretical uncertainties are
estimated by variations of the renormalisation/factorisation scales and of the
parton densities, the former being significantly reduced by the resummation
procedure. New limits at NLO+NLL on W' and Z' boson masses are obtained by
reinterpreting the latest ATLAS and CMS results in general extensions of the
Standard Model.
