  "abstract": "<p>A search for new charged massive gauge bosons, called ${W}^{\\prime }$, is performed with the ATLAS detector at the LHC, in proton\u2013proton collisions at a centre-of-mass energy of $\\sqrt{s}=8\\text{}\\text{TeV}$, using a dataset corresponding to an integrated luminosity of $20.3{\\text{fb}}^{-1}$. This analysis searches for ${W}^{\\prime }$ bosons in the ${W}^{\\prime }\\to t\\overline{b}$ 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 ${W}^{\\prime }$ bosons. No significant deviation from the Standard Model expectation is observed and limits are set on the ${W}^{\\prime }\\to t\\overline{b}$ cross-section times branching ratio and on the ${W}^{\\prime }$-boson effective couplings as a function of the ${W}^{\\prime }$-boson mass using the ${\\mathrm{CL}}_{s}$ procedure. For a left-handed (right-handed) ${W}^{\\prime }$ boson, masses below 1.70 (1.92) TeV are excluded at 95% confidence level.</p>",
