Abstract:

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=8 TeV, using a dataset corresponding to an integrated luminosity of 20.3 fb −1 . This analysis searches for W ′ bosons in the W ′ →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 ′ 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 ′ -boson effective couplings as a function of the W ′ -boson mass using the CL s procedure. For a left-handed (right-handed) W ′ boson, masses below 1.70 (1.92) TeV are excluded at 95% confidence level. © 2015
