|Abstract:||A search for new charged massive gauge bosons, called W′W′, is performed with the ATLAS detector at the LHC, in proton–proton collisions at a centre-of-mass energy of √s=8 TeV, using a dataset corresponding to an integrated luminosity of 20.3 fb⁻¹. This analysis searches for W′W′ bosons in theW′→tb⁻ decay channel in final states with electrons or muons, using a multivariate method based on boosted decision trees. The search covers masses between 0.5 and 3.0 TeV, for right-handed or left-handed W′W′ bosons. No significant deviation from the Standard Model expectation is observed and limits are set on the W′→tb⁻ cross-section times branching ratio and on the W′W′-boson effective couplings as a function of the W′W′-boson mass using the CLsCLs procedure. For a left-handed (right-handed) W′W′ boson, masses below 1.70 (1.92) TeV are excluded at 95% confidence level.|
