Book Description
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, 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 system. Assuming standard-model-like couplings and decay branching fractions, a W boson with a mass less than 1.32 TeV/c2 is excluded at the 95% confidence level.
