چکیده
Article history: Received 17 June 2014 Received in revised form 30 July 2014 Accepted 15 August 2014 Available online 20 August 2014 Editor: W.-D. Schlatter A search for resonant WZ production in the ν ′ ′ ( , ′ = e, μ) decay channel using 20.3 fb−1 of √s = 8 TeV pp collision data collected by the ATLAS experiment at LHC is presented. No significant deviation from the Standard Model prediction is observed and upper limits on the production cross sections of WZ resonances from an extended gauge model W ′ and from a simplified model of heavy vector triplets are derived. A corresponding observed (expected) lower mass limit of 1.52 (1.49) TeV is derived for the W ′ at the 95% confidence level. © 2014 CERN for the benefit of the ATLAS Collaboration.

متن کاملSearch for Supersymmetry and kinematic endpoint measurement in final states with two tau leptons with the ATLAS detector at the LHC
Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based on Monte Carlo simulation, a Supersymmetry signal selection is developed for fully hadronic, semileptonic and fully leptonic di-tau decays in events produced in proton-proto...
