Abstract (data abstract)
ATLAS-CERN-LHC. A measurement of the top-quark mass in the ttbar -> l+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 of the lepton from the $W$-boson decay and the muon originating from the b-hadron decay is reconstructed, and a binned-template profile likelihood fit is performed to extract the top mass. The measurement is based on proton-proton collision data corresponding to an integrated luminosity of 36.1 fb^-1 at a center-of-mass energy of 13 TeV provided by the Large Hadron Collider and recorded by the ATLAS detector.
