Detection of New Heavy Gauge Bosons W' in CMS

A first feasibility study of the search for a new heavy charged gauge boson with the CMS detector at the Large Hadron Collider LHC is presented. The used model assumes the existence of a heavy carbon copy of the Standard Model W (Reference Model by Altarelli), generically denoted as W'. Such a boson has been investigated in the decay channel W' --> mu nu using the full detector simulation including minimum bias events (pile-up) according to the luminosity expected in the first years. All relevant Standard Model backgrounds have been considered. Such a new boson is expected to be discovered, if existing, with a mass up to 4.6 TeV for an integrated luminosity of 10 fb^-1. The range can be expanded to 6.1 TeV with an integrated luminosity of 300 fb^-1. If no signs for a Wprime boson appear 95 % CL exclusion limits of 4.7 TeV and 6.2 TeV can be set, respectively.
