Abstract
We present a next-to-leading order (NLO) treatment of the production of a new charged heavy vector boson, generically called W', at hadron colliders via the Drell-Yan process. We fully consider the interference effects with the Standard Model W boson and allow for arbitrary chiral couplings to quarks and leptons. We present results at both leading order (LO) and NLO in QCD using the MC@NLO/Herwig++ and POWHEG methods. We derive observation curves on the mass-width plane for the LO case and give the significance for a sample of NLO mass-width points. The event generator used, Wpnlo, is fully customisable and publicly available.
