Title: Top quark mass measurement using the template method at CDF

Abstract

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.

Measurements of the top-quark decay width and mass at CDF using the template method.

Thesis/Dissertation Tang, Jian

Measurements of the top quark decay width and mass are presented using the tt events produced in p p collisions at Fermilab's Tevatron collider and collected by the CDF II detector. A data sample corresponding to 4.3 fb^-1 of integrated luminosity is used for the top quark width measurement. Two estimators, the reconstructed top quark mass and the mass of hadronically decaying W boson that comes from the top-quark decay are reconstructed for each event and compared with templates of different input top quark widths and deviations from nominal CDF jet energy scale (ΔJES) to perform a simultaneous fit formore »« less

Measurement of the top quark mass at CDF using the `neutrino phi weighting' template method on a lepton plus isolated track sample

Journal Article Aaltonen, T ; /Helsinki Inst. of Phys. ; Adelman, J ; ... - Submitted to Phys.Rev.D

We present a measurement of the top quark mass with t{bar t} dilepton events produced in p{bar p} collisions at the Fermilab Tevatron ({radical}s = 1.96 TeV) and collected by the CDF II detector. A sample of 328 events with a charged electron or muon and an isolated track, corresponding to an integrated luminosity of 2.9 fb{sup -1}, are selected as t{bar t} candidates. To account for the unconstrained event kinematics, we scan over the phase space of the azimuthal angles ({phi}{sub {nu}1}, {phi}{sub {nu}2}) of neutrinos and reconstruct the top quark mass for each {phi}{sub {nu}1}, {phi}{sub {nu}2} pairmore »« less
