Abstract

The mass of the top quark is measured using a sample of TeX candidate events with one electron or muon and at least four jets in the final state, collected by CMS in pp collisions at TeX TeV at the LHC. A total of 5174 candidate events is selected from data corresponding to an integrated luminosity of 5.0 fb−1. For each event the mass is reconstructed from a kinematic fit of the decay products to a TeX hypothesis. The top-quark mass is determined simultaneously with the jet energy scale (JES), constrained by the known mass of the W boson in TeX decays, to be 173.49 ± 0.43 (stat. + JES) ±0.98 (syst.) GeV.
