Top quark mass measurement using the template method at CDF
We present a measurement of the top quark mass in the lepton+jets and dilepton channels of tt[over-bar] decays using the data sample corresponding to an integrated luminosity of 5.6 fb[superscript -1] of pp[over-bar] collisions at Tevatron with [sqrt]s=1.96 TeV, collected with the CDF II detector....

| description | We present a measurement of the top quark mass in the lepton+jets and dilepton channels of tt[over-bar] decays using the data sample corresponding to an integrated luminosity of 5.6 fb[superscript -1] of pp[over-bar] collisions at Tevatron with [sqrt]s=1.96 TeV, collected with the CDF II detector. We construct templates of two reconstructed top quark masses from different jets-to-quarks combinations and the invariant mass of two jets from the W decays in the lepton+jets channel, and a reconstructed top quark mass and mT2, a variable related to the transverse mass in events with two missing particles, in the dilepton channel. The simultaneous fit of the templates from signal and background events in the lepton+jets and dilepton channels to the data yields a measured top quark mass of M[subscript top]=172.1±1.1(stat)±0.9(syst) GeV/c[superscript 2]. |
