Description

QCD resummation predictions for the production of W′ and Z′ heavy gauge bosons decaying leptonically will be presented. The results of our resummation code at next-to-leading order and next-to-leading logarithmic accuracy will be compared to Monte Carlo predictions obtained with PYTHIA at leading order supplemented with parton showers and FEWZ at NLO and next-to-next-to-leading order for the pT -differential and total cross sections in the Sequential Standard Model and general SU(2)×SU(2)×U(1) models. Finally, new limits at NLO+NLL on W′ and Z′ boson masses obtained by reinterpreting recent ATLAS and CMS results in general extensions of the Standard Model will be presented.
