Search for high-mass states with one lepton plus missing transverse momentum in proton–proton collisions at s=7 TeV with the ATLAS detector
The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W ′ ,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 l...

| Sumario: | The ATLAS detector is used to search for high-mass states, such as heavy charged gauge bosons (W ′ ,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 −1 . No excess beyond standard model expectations is observed. A W ′ 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. © 2011 CERN |
