Measurement of the b-hadron production cross section using decays to mu(-DX)-X-0 final states in p(p)over-bar collisions at root s=1.96 TeV
(American Physical Society, 2009-05)
We report a measurement of the production cross section for b hadrons in pp-bar collisions at √s=1.96 TeV. Using a data sample derived from an integrated luminosity of 83 pb[superscript -1] collected with the upgraded ...
Search for the Production of Narrow tb-bar Resonances in 1.9 fb-1 of pp-bar Collisions at sqrt[s]=1.96 TeV
(American Physical Society, 2009-07)
We present new limits on resonant tb̅ production in pp̅ collisions at √s=1.96 TeV, using 1.9 fb[superscript -1] of data recorded with the CDF II detector at the Fermilab Tevatron. We reconstruct a candidate tb̅ mass ...
Observation of the Omega [subscript b][superscript -] baryon and measurement of the properties of the Xi[subscript b][superscript -] and Omega [subscript b][superscript -] baryons
(American Physical Society, 2009-10)
We report the observation of the bottom, doubly-strange baryon Ω[subscript b][superscript -] through the decay chain Ω[subscript b][superscript -]→J/ψΩ[superscript -], where J/ψ→μ[superscript +]μ[superscript -], Ω[superscript ...
Search for the Associated Production of the Standard-Model Higgs Boson in the All-Hadronic Channel
(American Physical Society, 2009-11)
We report on a search for the standard-model Higgs boson in pp̅ collisions at √s=1.96 TeV using an integrated luminosity of 2.0 fb[superscript -1]. We look for production of the Higgs boson decaying to a pair of bottom ...
Measurement of the tt-bar cross section in pp-bar collisions at sqrt[s]=1.96 TeV using dilepton events with a lepton plus track selection
(American Physical Society, 2009-06)
This paper reports a measurement of the cross section for the pair production of top quarks in pp̅ collisions at √s=1.96 TeV at the Fermilab Tevatron. The data were collected from the CDF run II detector in a set of runs ...
Search for new particles decaying into dijets in proton-antiproton collisions at sqrt[s]=1.96 TeV
(American Physical Society, 2009-06)
We present a search for new particles which produce narrow two-jet (dijet) resonances using proton-antiproton collision data corresponding to an integrated luminosity of 1.13 fb[superscript -1] collected with the CDF II ...
Production of psi (2S) mesons in pp-bar collisions at 1.96 TeV
(American Physical Society, 2009-08)
We have measured the differential cross section for the inclusive production of ψ(2S) mesons decaying to μ[superscript +]μ[superscript -] that were produced in prompt or B-decay processes from pp̅ collisions at 1.96 TeV. ...
Search for the neutral current top quark decay t-->Zc using the ratio of Z-boson+4 jets to W-boson+4 jets production
(American Physical Society, 2009-09)
We have used the Collider Detector at Fermilab (CDF-II) to search for the flavor-changing neutral-current (FCNC) top-quark decay t→Zc using a technique employing ratios of W and Z production, measured in pp̅ data corresponding ...
Observation of New Charmless Decays of Bottom Hadrons
(American Physical Society, 2009-07)
We search for new charmless decays of neutral b hadrons to pairs of charged hadrons, using 1 fb[superscript -1] of data collected by the CDF II detector at the Fermilab Tevatron. We report the first observation of the ...
Evidence for a Narrow Near-Threshold Structure in the J/ psi phi Mass Spectrum in B+-->J/ psi phi K+ Decays
(American Physical Society, 2009-06)
Evidence is reported for a narrow structure near the J/ψϕ threshold in exclusive B+→J/ψϕK+ decays produced in (p)over-bar p collisions at √s=1.96 TeV. A signal of 14±5 events, with statistical significance in excess of ...
