چکیده
We report a measurement of the top-quark mass using events collected by the CDF II detector from pp collisions at square root of s = 1.96 TeV at the Fermilab Tevatron. We calculate a likelihood function for the top-quark mass in events that are consistent with tt --> bl(-)nu(l)bl'+ nu'(l) decays. The likelihood is formed as the convolution of the leading-order matrix element and detector resolution functions. The joint likelihood is the product of likelihoods for each of 33 events collected in 340 pb(-1) of integrated luminosity, yielding a top-quark mass M(t) = 165.2 +/- 6.1(stat) +/- 3.4(syst) GeV/c2. This first application of a matrix-element technique to tt --> bl+ nu(l)bl'- nu(l') decays gives the most precise single measurement of M(t) in dilepton events. Combined with other CDF run II measurements using dilepton events, we measure M(t) = 167.9 +/- 5.2(stat) +/- 3.7(syst) GeV/c2.

We report on a simultaneous measurement of the top quark mass (Mtop) in the Lepton+Jets and Dilepton channels using pp̄ collisions at √ s = 1.96 TeV from 4.8 fb −1 of data collected with the CDF detector at the Fermilab Tevatron. In the Lepton+Jets channel, a top quark mass (m t ) is reconstructed for every event by minimizing a χ-like function to the overconstrained kinematics of the tt̄ system....

We measure the top quark mass in tt̄ events using up to 3.6 fb of pp̄ collisions at √ s = 2 TeV. New results are described for matrix element methods with single lepton and dilepton channels, and template methods with all-jets and dilepton channels. Standardization of systematic uncertainties has proceeded between the CDF and D0 collaborations. A combined measurement of 173.1 ± 0.6(stat) ± 1.1(sy...
متن کاملSearch for Pair Production of Stop Quarks Mimicking Top Event Signatures
We update our search for the pair-produced super-symmetric partner of the top quark (stop quark) from 1.9fb−1 to 2.7fb−1 of data collected with CDF II. We search for the scalar top quarks via their decay channel: t̃1 → b + χ̃1 → b+χ̃1+ν+` which gives an event signature similar to that of a top dilepton event. We reconstruct events under the stop decay hypothesis and use the reconstructed stop mass...
