Abstract:

A new heavy gauge boson, W', decaying to a muon and a neutrino, is searched for in pp collisions at a
centre-of-mass energy of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an
integrated luminosity of 36 pb−1. No significant excess of events above the standard model expectation
is found in the transverse mass distribution of the muon–neutrino system. Masses below 1.40 TeV are
excluded at the 95% confidence level for a sequential standard-model-like W'. The W' mass lower limit
increases to 1.58 TeV when the present analysis is combined with the CMS result for the electron channel.
