Measurement of the top-quark mass using a leptonic invariant mass in pp collisions at CMS = 13 TeV with the ATLAS detector
Original language description
A measurement of the top-quark mass (mt) in the t-t ! lepton+jets channel ispresented, with an experimental technique which exploits semileptonic decays of b-hadronsproduced in the top-quark decay chain. The distribution of the invariant mass m'μ ofthe lepton, ' (with ' = e, μ), from the W-boson decay and the muon, μ, originatingfrom the b-hadron decay is reconstructed, and a binned-template profile likelihood fit isperformed to extract mt. The measurement is based on data corresponding to an integratedluminosity of 36.1 fb-1 of CMS = 13 TeV pp collisions provided by the Large Hadron Colliderand recorded by the ATLAS detector. The measured value of the top-quark mass ismt = 174.41 +- 0.39 (stat.) +- 0.66 (syst.) +- 0.25 (recoil) GeV, where the third uncertaintyarises from changing the Pythia8 parton shower gluon-recoil scheme, used in top-quarkdecays, to a recently developed setup.
