et al.

We present a measurement of the top quark mass in the lepton+jets and dilepton channels of t$$\bar{t}$$ decays using the template method. The data sample corresponds to an integrated luminosity of 5.6 fb^-1 of p$$\bar{p}$$ collisions at Tevatron with √s = 1.96 TeV, collected with the CDF II detector. The measurement is performed by constructing templates of three kinematic variables in the lepton+jets and two kinematic variables in the dilepton channel. The variables are two reconstructed top quark masses from different jets-to-quarks combinations and the invariant mass of two jets from the W decay in the lepton+jets channel, and a reconstructed top quark mass and m_T2, 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_top = 172.1±1.1 (stat)±0.9 (syst) GeV/c².
