چکیده
This Letter reports a search for a narrow resonant state decaying into two W bosons and two b quarks where one W boson decays leptonically and the other decays into a quark-antiquark pair. The search is particularly sensitive to top-antitop resonant production. We use the full data sample of proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected by the CDF II detector at the Fermilab Tevatron, corresponding to an integrated luminosity of 9.45 fb(-1). No evidence for resonant production is found, and upper limits on the production cross section times branching ratio for a narrow resonant state are extracted. Within a specific benchmark model, we exclude a Z' boson with mass, M(Z'), below 915 GeV/c(2) decaying into a top-antitop pair at the 95% credibility level assuming a Z' boson decay width of Γ(Z') = 0.012 M(Z'). This is the most sensitive search for a narrow qq-initiated tt resonance in the mass region below 750 GeV/c(2).

The first search for electroweak single top quark production from the exchange of an s-channel virtual W boson using a data sample composed of events with an imbalance in the total transverse momentum, b-tagged jets, and no identified leptons (/ ET bb̄) is presented.

متن کاملMeasurement of Single Top Quark Production in 7.5 fb−1 of CDF Data Using Neural Networks
We report a measurement of single top quark production in lepton plus jets final state using 7.5 fb−1 of pp̄ collision data collected by CDF Run II experiment. We select events in the W + jets topology consistent with the signature of a charged lepton (electron or muon), large missing transverse energy ( 6 ET ) from the W boson decay and two or three jets, at least one of them is required to be ...
متن کاملSearches for Resonances Decaying to Top
The top quark was discovered in 1995 by the CDF and D0 collaborations [2, 3]. During Run I (1992-1996) both experiments collected a data set of about 125 pb. In 2001 Run II has started operating with a center-of-mass-energy of √ s = 1.96 TeV and an increased luminosity. One of the main aims is to further investigate the properties of top quarks. End of 2006 there was first evidence for single t...
متن کاملTop-Antitop Production and Decay Events
We have analyzed the available data on pp̄ → t t̄ followed by the decays (t → bW+, t̄ → b̄W) which lead to eμ2jets or l4jets configurations, using a likelihood method we proposed earlier. The outcome is compared with the recent CDF analysis. In an appendix, we discuss the nature of the additional “slow” μ+ observed in one CDF dilepton event, concluding that it is most probably a “tertiary lepton” r...
متن کاملTop Mass Measurement at Cdf
We report on recent measurements of the top quark mass using tt̄ candidate events selected in ≃ 320 pb of data from the ”Run II” operation period of the Tevatron pp̄ collider. More emphasis is given on the best single measurement to date (Mtop = 173.5 +3.9 −3.8 GeV/c ), provided by CDF using the ”lepton plus jets” channel, where one W decays to a lepton-neutrino pair and the other into quarks (to...

We present three recent analyses (Abstracts 169, 170 and 174) of the mass of the top quark (Mt) using top-antitop candidate events collected by the D0 experiment at the Fermilab Tevatron Collider: (i) a 3.6 events/fb sample of data in the lepton+jets channel analyzed to extract a precision value of Mt using the "Matrix-Element" (ME) method, wherein each event probability is calculated from the ...
