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 tt̅ decays using the data sample corresponding to an integrated luminosity of 5.6 fb-1 of pp̅ collisions at Tevatron with √s=1.96 TeV, collected with the CDF II detector. We construct templates of two recons...

We present a measurement of the top quark mass in the lepton+jets and dilepton channels of tt̅ decays using the data sample corresponding to an integrated luminosity of 5.6 fb-1 of pp̅ collisions at Tevatron with √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 Mtop=172.1±1.1(stat)±0.9(syst) GeV/c2. |
