Measurement of direct CP asymmetry in B± → J/ K± decays produced in pp̅ collisions at √s = 1.96TeV
… 6fb−1 of pp̄ collisions at √s = 1.96TeV from the CDF detector at the Fermi National Accelerator Laboratory. Approximately 80,000 B− → J/ K− (and charge conjugate) events were selected on the dimuon trigger and the yields were determined using a simultaneous mass and lifetime fit. After …

W mass measurement with muons at SQRT.S. = 1.8 TeV
… an analysis of $W \to\ \mu\ \nu$ decays in the CDF detector at the Fermilab Tevatron $\bar p p$ collider. The mass is 79.90 $\pm$ 0.53(stat.) $\pm$ 0.31(sys.) $\pm$ 0.16(scale) GeV/c$\sp2$. When this result is combined with previous CDF measurements, sin$\sp2\theta\sb{W}$ is determined to be …

A measurement of the mass of the W vector boson from antiproton proton going to charged W boson going to muon muon neutrino at 1.8 TeV
… collider run at the Fermilab Tevatron with the CDF detector. A fit to the transverse mass spectrum of a sample of 3268 $\rm W\to\mu\nu$ events from 19.7 $\rm pb\sp{-1}$ of data yields a mass of $M\sbsp{W}{\mu} = 80.310 \pm 0.205$ (stat.) $\pm$ 0.120 (syst.) $\pm$ 0.050 (scale). This result is …

Measurement of the mass and width of the Z boson from Z going to positron-electron decay in antiproton-proton collisions at sqrt.s = 1.8 TeV
… The Z $\to$ e$\sp{+}$e$\sp{-}$ data from the CDF detector yields a mass of the Z boson of M$\sb{\rm Z}$ = 90.78 $\pm$ 0.40(stat.) $\pm$ 0.38(syst.) $\pm$ 0.2(scale) GeV/c$\sp2$ and a width of $\Gamma\sb{\rm Z}$ = 2.8 $\pm$ 1.0(stat.) $\pm$ 0.5(syst.) GeV.

Observation of W [right arrow] [mu][nu] decays in proton-antiproton collisions at [square root]s = 1.8 TeV
… the Fermilab Tevatron collider. Details of the CDF detector are given and event selection criteria are developed. A cross section times branching ratio, based on a sample of three W --+ J-lV candidate events extracted from 27.2 ± 4.1 nb-1 of data taken in the 1987 collider run, is calculated to …

A measurement of the inclusive differential Drell-Yan cross-section with dimuons at sqrt.s = 1.8 TeV
… pseudorapidity region of $-0.6<\eta<0.6$ of the CDF detector. The differential cross section $d\sigma/dMdY\vert\sb{Y=0}$ is measured for dimuon invariant masses between 11 GeV/c$\sp2$ and 40 GeV/c$\sp2$ and is compared to next-to-leading order theoretical predictions. The …

Direct Photon Differential Cross Section in p̄p Collisions at the Square Root of s = 1.8 TeV
<p>Data taken from the Collider Detector at Fermilab (CDF) during the 1992-1993 run are used to measure the cross section for production of isolated prompt photons in p̄p collisions at √s = 1.8 TeV. Prompt photon production in p̄p collisions is sensitive to the gluon structure function of the …
