Title: Measurement of the top quark mass with lepton+jets final states using pp collisions at $$\sqrt{s}=$$ 13 TeV

Abstract

The mass of the top quark is measured using a sample of $$\mathrm{t\overline{t}}$$ events containing one isolated muon or electron and at least four jets in the final state, collected by the CMS detector using proton-proton collisions at $$\sqrt{s}=$$ 13 TeV at the CERN LHC. The events are selected from data corresponding to an integrated luminosity of 35.9 fb$$^{-1}$$. For each event the mass is reconstructed from a kinematic fit of the decay products to a \ttbar hypothesis. Using the ideogram method, the top quark mass is determined simultaneously with an overall jet energy scale factor (JSF), constrained by the mass of the W boson in $$\mathrm{q\overline{q}'}$$ decays. The measurement is calibrated on samples simulated at next-to-leading order matched to a leading-order parton shower. The top quark mass is found to be 172.25$$\pm$$0.08 (stat+JSF)$$\pm$$0.62 (syst) GeV. The dependence of this result on the kinematic properties of the event is studied and compared to predictions of different models of $$\mathrm{t\overline{t}}$$ production, and no indications of a bias in the measurements are observed.
