Search for high-mass states with one lepton plus missing transverse momentum in proton-proton collisions at {radical}(s)=7 TeV with the ATLAS detector

Abstract

The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W{sup '},W*), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 36 pb{sup -1}. No excess beyond standard model expectations is observed. A W{sup '} with sequential standard model couplings is excluded at 95% confidence level for masses below 1.49 TeV, and a W* (charged chiral boson) for masses below 1.35 TeV.
