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 T miss , using proton–proton collision data corresponding to an integrated luminosity of 36 ? pb ? 1 . No excess above standard model expectations is seen in the transverse mass distribution of the electron- E T miss system. Assuming standard-model-like couplings and decay branching fractions, a W ′ boson with a mass less than 1.36 ? TeV / c 2 is excluded at 95% confidence level.
