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 …

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 study of ${B}_{s}^{0}$ decays to the $CP$-odd final state $J/\ensuremath{\psi}{f}_{0}(980)$ with $J/\ensuremath{\psi}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and ${f}_{0}(980)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. Using $p\overline{p}$ collision data with an integrated luminosity of $3.8\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the CDF II detector at the Tevatron we measure a ${B}_{s}^{0}$ …

We reconstruct ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}D{K}^{\ifmmode\pm\else\textpm\fi{}}$ decays in a data sample collected by the CDF II detector at the Tevatron collider corresponding to $1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity. We select decay modes where the $D$ meson decays to either ${K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ (flavor eigenstate) or ${K}^{\ensuremath{-}}{K}^{+}$, …

Limits on the Higgs boson production rate are obtained …

This Letter describes the first determination of bounds on the $CP$-violation parameter $2{\ensuremath{\beta}}_{s}$ using ${B}_{s}^{0}$ decays in which the flavor of the bottom meson at production is identified. The result is based on approximately 2000 ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ decays reconstructed in a $1.35\text{ }\text{ …

We present a measurement of ${R}_{\mathcal{B}}$, the ratio of the branching fraction for the rare decay ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ to that for the Cabibbo-favored decay ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$. Charge-conjugate decays are implicitly included. A signal of $2005\ifmmode\pm\else\textpm\fi{}104$ events for the decay ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ is obtained using the …
