Abstract:

A search for new charged massive gauge bosons, W ′ , is performed with the ATLAS detector at the LHC. Data were collected in proton–proton collisions at a center-of-mass energy of s=13 TeV and correspond to an integrated luminosity of 36.1 fb −1 . This analysis searches for W ′ bosons in the W ′ →tb¯ decay channel in final states with an electron or muon plus jets. The search covers resonance masses between 0.5 and 5.0 TeV and considers right-handed W ′ bosons. No significant deviation from the Standard Model (SM) expectation is observed and upper limits are set on the W ′ →tb¯ cross section times branching ratio and the W ′ boson effective couplings as a function of the W ′ boson mass. For right-handed W ′ bosons with coupling to the SM particles equal to the SM weak coupling constant, masses below 3.15 TeV are excluded at the 95% confidence level. This search is also combined with a previously published ATLAS result for W ′ →tb¯ in the fully hadronic final state. Using the combined searches, right-handed W ′ bosons with masses below 3.25 TeV are excluded at the 95% confidence level. © 2018 The Author(s)
