【 摘 要 】

A search for a heavy gauge boson W′ has been conducted by the CMS experiment at the LHC in the decay channel with an electron and large transverse energy imbalance E[miss over T], using proton–proton collision data corresponding to an integrated luminosity of 36 pb[superscript -1]. No excess above standard model expectations is seen in the transverse mass distribution of the electron-E[miss over T] system. Assuming standard-model-like couplings and decay branching fractions, a W′ boson with a mass less than 1.36 [TeV over c [superscript 2]] is excluded at 95% confidence level.
