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 …

This paper describes a measurement of the top quark mass, ${M}_{\mathrm{top}}$, with the dynamical likelihood method (DLM) using the CDF II detector at the Fermilab Tevatron. The Tevatron produces top/antitop ($t\overline{t}$) pairs in $p\overline{p}$ collisions at a center-of-mass energy of 1.96 TeV. …

This article presents a measurement of the top quark mass using the CDF II detector at Fermilab. Colliding beams of protons and antiprotons at Fermilab's Tevatron ($\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$) produce top/antitop pairs, which decay to ${W}^{+}{W}^{\ensuremath{-}}b\overline{b}$; events are selected where one $W$ …

We report on a search for the pair production of scalar leptoquarks (LQ), using $191\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of proton-antiproton collision data recorded by the CDF experiment during Run II of the Tevatron. The leptoquarks are sought via their decay into a neutrino …

We report a measurement of the $t\overline{t}$ production cross section using the CDF II detector at the Fermilab Tevatron. The data consist of events with an energetic electron or muon, missing transverse energy, and three or more hadronic jets, at least one …

We present a measurement of the $t\overline{t}$ production cross section using events with one charged lepton and jets from $p\overline{p}$ collisions at a center-of-mass energy of 1.96 TeV. In these events, heavy flavor quarks from top quark decay are identified with a …

We report a measurement of the ratio of the bottom quark production cross section in antiproton-proton collisions at $\sqrt{s}=630 \mathrm{GeV}$ to 1800 GeV using bottom quarks with transverse momenta greater than 10.75 GeV identified through their semileptonic decays and long lifetimes. The …

An angular analysis of ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}$ and ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\varphi}$ has been used to determine the decay amplitudes with parity-even longitudinal ( ${A}_{0}$) and transverse ( ${A}_{\ensuremath{\parallel}}$) polarization and parity-odd transverse ( ${A}_{\ensuremath{\perp}}$) polarization. The measurements are based on 190 ${B}^{0}$ and 40 ${B}_{s}^{0}$ candidates …

This Letter describes a direct measurement of the $W$ boson total decay width, ${\ensuremath{\Gamma}}_{W}$, using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of $90{\mathrm{pb}}^{\ensuremath{-}1}$, collected during the 1994--1995 run of the Fermilab Tevatron $p\overline{p}$ collider. The width is …

This Letter describes a direct search for charged Higgs boson production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ recorded by the Collider Detector at Fermilab. Two-Higgs-double extensions to the standard model predict the existence of charged Higgs bosons $({H}^{\ifmmode\pm\else\textpm\fi{}})$. In such models, the branching …

The lifetimes of the ${B}^{\ensuremath{-}}$ and ${\overline{B}}^{0}$ mesons are measured using the partially reconstructed semileptonic decays $\overline{B}\ensuremath{\rightarrow}D{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}X$, where D is either a ${D}^{0}$ or ${D}^{*+}$ meson. The data were collected by the CDF detector at the Fermilab Tevatron collider during 1992--1993 and …
