Abstract
A recent search for heavy resonances, namely W bosons, decaying to a top quark and a bottom quark with a lepton and missing transverse momentum plus jets in the final state is presented. The analysed data come from proton-proton collision and correspond to an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector at the Large Hadron Collider at √s = 13 TeV. No significant excess of data over the Standard Model prediction is found and the results are expressed as upper limits on the W → t¯b production cross-section times branching ratio as a function of the W boson mass. The production of right-handed W bosons is excluded at 95% confidence level for masses below 3.15 TeV. A prospect for this search at the high luminosity LHC is also reported, showing the expected sensitivity for an integrated luminosity of 3000 fb−1 and a centre-of-mass of √s = 14 TeV.
