Search for W′ → tb decays in the hadronic final state using pp collisions at √s=13TeV with the ATLAS detector
A search for W ′ -boson production in the W ′ →tb¯→qq¯ ′ bb¯ decay channel is presented using 36.1fb −1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search is interpreted in terms of both a left-handed and a right-handed ch...
