We report the results of a search for the anomalous production of a massive particle decaying to four electrons via two ${Z}^{0}$ bosons in $1.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ collected by the CDF II detector at Fermilab. …

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 measure the mean lifetime $\ensuremath{\tau}=2/({\ensuremath{\Gamma}}_{L}+{\ensuremath{\Gamma}}_{H})$ and the decay-width difference $\ensuremath{\Delta}\ensuremath{\Gamma}={\ensuremath{\Gamma}}_{L}\ensuremath{-}{\ensuremath{\Gamma}}_{H}$ of the light and heavy mass eigenstates of the ${B}_{s}^{0}$ meson, ${B}_{sL}^{0}$ and ${B}_{sH}^{0}$, in ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ decays using $1.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the CDF II detector at the …

We report the observation of two narrow resonances consistent with states of orbitally excited (L=1) B_(s) mesons using 1 fb;(-1) of pp[over ] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II detector at the Fermilab Tevatron. We use …

We have performed a search for new particles which decay to two photons using $1.2\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity from $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ collected using the CDF II detector at the Fermilab Tevatron. We find the diphoton mass …

We report on measurements of the inclusive jet production cross section as a function of the jet transverse momentum in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$, using the ${k}_{\mathrm{T}}$ algorithm and a data sample corresponding to $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the …

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 on a search for the flavor-changing neutral current decay ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ in $p\overline{p}$ collisions at $\sqrt{s}=1.96\mathrm{TeV}$ using $65{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected by the CDF II experiment at the Fermilab Tevatron Collider.
