Abstract

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 ETmiss, 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-ETmiss system. Assuming standard-model-like couplings and decay branching fractions, a W‧ boson with a mass less than 1.36 TeV/c2 is excluded at 95% confidence level.
