Description: A search for new charged massive gauge bosons, called W, is performed with the ATLAS detector at the LHC, in proton–proton collisions at a centre-of-mass energy of √s=8TeV, using a dataset corresponding to an integrated luminosity of 20.3fb−1. This analysis searches for Wbosons in the W→t¯bdecay 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 3.0TeV, for right-handed or left-handed Wbosons. No significant deviation from the Standard Model expectation is observed and limits are set on the W→t¯bcross-section times branching ratio and on the W-boson effective couplings as a function of the W-boson mass using the CLsprocedure. For a left-handed (right-handed) Wboson, masses below 1.70 (1.92)TeVare excluded at 95% confidence level.
