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 …

Analysis of B [sigma] flavor oscillations at CDF
… oscillations using data collected with the CDF detector. The data samples are formed of both fully and partially reconstructed B meson decays, B, -+ D7r(irir) and B8 -- Dalv. A likelihood fitting framework is implemented and appropriate models and techniques developed for describing the …

Observation of B⁰s - B⁻⁰s oscillations and the development and application of same-side-kaon flavor tagging
… Bs oscillations, using data collected with the CDF detector. The sub-percent precision of the measurement is also noteworthy. The data sample used for this analysis includes fully and partially reconstructed Bdecays: ... The focus of this thesis is the algorithm of same-side-kaon tagging which …

A study of QCD processes at low momentum transfer in hadron-hadron collisions
… source of systematic error for the inclusive CDF jet cross section at low transverse momentum. The actual assumption is that the underlying event energy is similar to the energy found in soft events (minimum bias events). We examined both jet and minimum bias events using data from the CDF …

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 …
