The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measuremen

We report a measurement of the forward-backward asymmetry, A(FB), in b (b) over bar pairs produced in proton-antiproton collisions and identified by muons from semileptonic b-hadron decays. The event sample is collected at a center-of-mass energy of

A measurement of vector boson (V) production in conjunction with a D*(2010)(+) meson is presented. Using a data sample corresponding to 9.7 fb(-1) of proton-antiproton collisions at center-of-mass energy root s = 1.96 TeV produced by the Fermilab Tev

A search for a Higgs boson with suppressed couplings to fermions, h(f), assumed to be the neutral, lower-mass partner of the Higgs boson discovered at the Large Hadron Collider, is reported. Such a Higgs boson could exist in extensions of the standar

Measurement of the B-c(+/-) production cross section in p(p)over-tilde collisions at root s=1.96 TeV
We describe a measurement of the ratio of the cross sections times branching fractions of the B-c(+) meson in the decay mode B-c(+) -> J/psi mu(+)nu to the B+ meson in the decay mode B+ -> J/psi K+ in proton-antiproton collisions at center-of-mass en

Combined constraints from the CDF and D0 Collaborations on models of the Higgs boson with exotic spin J and parity P are presented and compared with results obtained assuming the standard model value J(P) = 0(+). Both collaborations analyzed approxim

Results of a study of the substructure of the highest transverse momentum (p(T)) jets observed by the CDF Collaboration are presented. Events containing at least one jet with p(T) > 400 GeV/c in a sample corresponding to an integrated luminosity of 5

Production of the Y(1S) meson in association with a vector boson is a rare process in the standard model with a cross section predicted to be below the sensitivity of the Tevatron. Observation of this process could signify contributions not described

We present a measurement of the top-quark mass in events containing two leptons (electrons or muons) with a large transverse momentum, two or more energetic jets, and a transverse-momentum imbalance. We use the full proton-antiproton collision data s
