Measurement of the top quark mass with lepton+jets final states using collisions at

The mass of the top quark is measured using a sample of $$ events collected by the CMS detector using proton-proton collisions at $$ $$ at the CERN LHC. Events are selected with one isolated muon or electron and at least four jets from data corresponding to an integrated luminosity of 35.9 $$ . For each event the mass is reconstructed from a kinematic fit of the decay products to a $$ hypothesis. Using the ideogram method, the top quark mass is determined simultaneously with an overall jet energy scale factor (JSF), constrained by the mass of the W boson in $$ 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 $$ . The dependence of this result on the kinematic properties of the event is studied and compared to predictions of different models of $$ production, and no indications of a bias in the measurements are observed.
