Abstract
The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (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 4. 7 fb-1. No excess beyond Standard Model expectations is observed. A W????????? with Sequential Standard Model couplings is excluded at the 95 % credibility level for masses up to 2. 55 TeV. Excited chiral bosons (W*) with equivalent coupling strength are excluded for masses up to 2. 42 TeV. ?????? 2012 CERN for the benefit of the ATLAS collaboration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
