Measurement of the top-quark mass using a leptonic invariant mass in pp collisions at s=13 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the top-quark mass (mt) in the tt¯ lepton+jets channel is presented, with an experimental technique which exploits semileptonic decays of b-hadrons produced in the top-quark decay chain. The distribution of the invariant mass mμ of the lepton, (with =e,μ), from the W-boson decay and the muon, μ, originating from the b-hadron decay is reconstructed, and a binned-template profile likelihood fit is performed to extract mt.
