Query: Search for leptonic decays of W' bosons in pp collisions at sqrt(s) = 7
  TeV   A search for a new heavy gauge boson W' decaying to an electron or muon, plus
a low mass neutrino, is presented. This study uses data corresponding to an
integrated luminosity of 5.0 inverse femtobarns, collected using the CMS
detector in pp collisions at a centre-of-mass energy of 7 TeV at the LHC.
Events containing a single electron or muon and missing transverse momentum are
analyzed. No significant excess of events above the standard model expectation
is found in the transverse mass distribution of the lepton-neutrino system, and
upper limits for cross sections above different transverse mass thresholds are
presented. Mass exclusion limits at 95% CL for a range of W' models are
determined, including a limit of 2.5 TeV for right-handed W' bosons with
standard-model-like couplings and limits of 2.43--2.63 TeV for left-handed W'
bosons, taking into account their interference with the standard model W boson.
Exclusion limits have also been set on Kaluza--Klein W[KK] states in the
framework of split universal extra dimensions.
