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 ...
First Observation of Vector Boson Pairs in a Hadronic Final State at the Tevatron Collider
(American Physical Society, 2009-08)
We present the first observation in hadronic collisions of the electroweak production of vector boson pairs (VV, V=W, Z) where one boson decays to a dijet final state. The data correspond to 3.5 fb[superscript -1] of ...
Top quark mass measurement in the tt[over -bar] all hadronic channel using a matrix element technique in pp[over -bar] collisions at sqrt[s]=1.96 TeV
(American Physical Society, 2009-04)
We present a measurement of the top quark mass in the all hadronic channel (tt̅→bb̅q[subscript 1]q̅[subscript 2]q[subscript 3]q̅[subscript 4] using 943 pb[superscript -1] of pp̅ collisions at √s=1.96 TeV collected at the ...
Top quark mass measurement in the lepton plus jets channel using a modified matrix element method
(American Physical Society, 2009-04)
We report a measurement of the top quark mass, m_t, obtained from pp̅ collisions at √s=1.96 TeV at the Fermilab Tevatron using the CDF II detector. We analyze a sample corresponding to an integrated luminosity of ...
Search for Charged Higgs Bosons in Decays of Top Quarks in pp-bar Collisions at sqrt s=1.96 TeV
(American Physical Society, 2009-09)
We report on the first direct search for charged Higgs bosons decaying into cs̅ in tt̅ events produced by pp̅ collisions at √s=1.96 TeV. The search uses a data sample corresponding to an integrated luminosity of ...
Measurement of the tt-bar production cross section in 2 fb-1 of pp-bar collisions at sqrt[s]=1.96 TeV using lepton plus jets events with soft muon b tagging
(American Physical Society, 2009-03)
We present a measurement of the tt̅ production cross section in pp̅ collisions at √s=1.96 TeV using events containing a high transverse momentum electron or muon, three or more jets, and missing transverse energy. Events ...
Measurement of particle production and inclusive differential cross sections in p(p)over-bar collisions at root s=1.96 TeV
(American Physical Society, 2009-06)
We report a set of measurements of particle production in inelastic p(p)over-bar collisions collected with a minimum-bias trigger at the Tevatron Collider with the CDF II experiment. The inclusive charged particle transverse ...
Measurement of the top quark mass using the invariant mass of lepton pairs in soft muon b-tagged events
(American Physical Society, 2009-09)
We present the first measurement of the mass of the top quark in a sample of tt̅ →ℓν̅ bb̅ qq̅ events (where ℓ=e,μ) selected by identifying jets containing a muon candidate from the semileptonic decay of heavy-flavor hadrons ...
Precision Measurement of the X(3872) Mass in J/ psi pi + pi - Decays

We present an analysis of the mass of the X(3872) reconstructed via its decay to J/ψπ[superscript +]π[superscript -] using 2.4 fb[superscript -1] of integrated luminosity from pp̅ collisions at √s=1.96 TeV, collected ...
