A search for tt resonances using lepton-plus-jets events in proton-proton collisions at s = 8 TeV with the ATLAS detector
Original language description
A search for new particles that decay into top quark pairs is reported. The search is performed with the ATLAS experiment at the LHC using an integrated luminosity of 20.3 fb1 of proton-proton collision data collected at a centre-of-mass energy of s=8 TeV. The lepton-plus-jets final state is used, where the top pair decays to W+bWb , with one W boson decaying leptonically and the other hadronically. The invariant mass spectrum of top quark pairs is examined for local excesses or deficits that are inconsistent with the Standard Model predictions. No evidence for a top quark pair resonance is found, and 95% confidence-level limits on the production rate are determined for massive states in benchmark models.
