Measurement of the top quark mass in the lepton+jets channel using the lepton transverse momentum

Abstract: This Letter reports a measurement of the top quark mass, , in data from collisions at corresponding to 2.7 fb?1 of integrated luminosity at the Fermilab Tevatron using the CDF II detector. Events with the topology are selected. An unbinned likelihood is constructed based on the dependence of the lepton transverse momentum, , on . A maximum likelihood fit to the data yields a measured mass . In this measurement, the contribution by the jet energy scale uncertainty to the systematic error is negligible. The result provides an important consistency test for other measurements where explicit use of the jet energy is made for deriving the top quark mass.
