We measure the particle-level forward-backward production asymmetry in $b\overline{b}$ pairs with masses (${m}_{b\overline{b}}$) larger than $150\text{ }\text{ }\mathrm{GeV}/{c}^{2}$, using events with hadronic jets and employing jet charge to distinguish $b$ from $\overline{b}$. The measurement uses $9.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $p\overline{p}$ collisions at …

The top-quark mass ${M}_{\text{top}}$ is measured using top quark-antiquark pairs produced in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV and that decay into a fully hadronic final state. The full data set collected with the CDF II detector at the …

We present a measurement of the ratio of the top-quark branching fractions $R=B(t\ensuremath{\rightarrow}Wb)/B(t\ensuremath{\rightarrow}Wq)$, where $q$ represents any quark flavor, in events with two charged leptons, imbalance in total transverse energy, and at least two jets. The measurement uses proton-antiproton collision data at …

Drell-Yan lepton pairs are produced in the process $p\overline{p}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}+X$ through an intermediate ${\ensuremath{\gamma}}^{*}/Z$ boson. The lepton angular distributions are used to provide information on the electroweak-mixing parameter ${sin}^{2}{\ensuremath{\theta}}_{W}$ via its observable effective-leptonic ${sin}^{2}{\ensuremath{\theta}}_{W}$, or ${sin}^{2}{\ensuremath{\theta}}_{\mathrm{eff}}^{\mathrm{lept}}$. A new method to infer ${sin}^{2}{\ensuremath{\theta}}_{W}$ or, …

We present a measurement of the ratio of the top-quark branching fractions $R=\mathcal{B}(t\ensuremath{\rightarrow}Wb)/\phantom{\rule{0ex}{0ex}}\mathcal{B}(t\ensuremath{\rightarrow}Wq)$, where $q$ represents quarks of type $b$, $s$, or $d$, in the final state with a lepton and hadronic jets. The measurement uses $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ proton-antiproton collision data …

The combination of searches performed by the CDF and D0 collaborations at the Fermilab Tevatron Collider for neutral Higgs bosons produced in association with $b$ quarks is reported. The data, corresponding to $2.6\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity at CDF and $5.2\text{ …

We present a measurement of the $CP$-violating parameter ${\ensuremath{\beta}}_{s}^{J/\ensuremath{\psi}\ensuremath{\phi}}$ using approximately 6500 ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ decays reconstructed with the CDF II detector in a sample of $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ corresponding to $5.2\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ integrated luminosity produced by the Tevatron collider …

A multivariate likelihood method to measure electroweak couplings with the Drell--Yan process at the LHC is presented. The process is described by the dilepton rapidity, invariant mass, and decay angle distributions. The decay angle ambiguity due to the unknown assignment of the …
