Measurement of the Diffractive Structure Function of the Antiproton in Proton-Antiproton Collisions at √s = 1800 and 630 GeV
… diffractive structure function FjjD of the antiproton obtained from a study of single diffractive dijet events produced in association with a leading antiproton in pp̄ collisions at the center-of-mass energy √s = 1800 and 630 GeV is presented. Inclusive samples of single diffractive events …

Search for Second-Generation Leptoquarks in Proton-Antiproton Collisions
… leptoquarks (LQ_2) in around 114 pb^-1 of proton-antiproton collisions, recorded with the D0 detector between September 2002 and June 2003 at a centre-of-mass energy of sqrt{s} = 1.96 TeV. The predictions of the Standard Model and models including scalar leptoquark production are compared to the …

Design Of A High Luminosity 100 Tev Proton Antiproton Collider
… A 10 34 cm-2 s-1 luminosity 100 TeV proton-antiproton collider is explored with 7× the energy of the LHC. The dipoles are 4.5 T to reduce cost. A proton-antiproton collider is selected as a future machine for several reasons. The cross section for many high mass states is 10 times higher in …

A search for top quarks in proton-antiproton collisions using dileptons
A search for tt pairs in pp collisions with a center of mass energy $\sqrt s$ = 1.8TeV is presented. The analysis looks for tt pairs which decayed through the chain $\bar {tt}\to W\sp+bW\sp-\bar b\to\ell\sp+\bar \nu b\ell\sp-\nu\bar b$ where one of the b quarks is explicitly identified. In a sample …

Study of muons associated with jets in proton-antiproton collisions at sqrt.s = 1.8 TeV
Production of heavy quark flavors in proton-antiproton collisions with a center-of-mass energy of 1.8 $\times$ 10$\sp{12}$ electron volts is studied for events containing hadronic jets with a nearby muon track, where both the jet and the muon are produced at large angles from the incident beams. …

Measurement of Z Boson Transverse Momentum In Proton-Antiproton Collisions At sqrt(s)=1.96 TeV
This dissertation describes a measurement of the shape of the boson transverse momentum distribution in $p\bar{p}\rightarrow Z/\gamma^{*}\rightarrow e^+e^- +X$ events at a center-of-mass energy of 1.96 TeV. The measurement is made for events with electron-positron mass between $70 < M_{ee} < 110$ …

Observation of tungsten ---> muon-neutrino decays in proton-antiproton collisions at sqrt. s = 1.8 TeV
… positively charged kaons, produced in proton-antiproton annihilations at rest, has been measured with good momentum resolution $(\delta p/p$ = 1.5%) and high statistics ($\sim$300,000 potential decays). The data were obtained with the Experiment PS183 magnetic pair spectrometer at LEAR, the …

A search for signatures of dark matter in the AMS-01 electron and antiproton spectrum
… -1 spectrum of AMS-01 (essentially electrons and antiprotons). To avoid model dependent complications we assume that the primary annihilation channel is through W+W- production. We use the galactic propagation software GALPROP to determine the dark matter spectra at Earth from a smooth isothermal …

Study of muons associated with jets in proton-antiproton collision at [square root]s = 1.8 TeV
Production of heavy quark flavors in proton-antiproton collisions with a centerof- mass energy of 1.8 x 1012 electron volts is studied for events containing hadronic jets with a nearby muon track, where both the jet and the muon are produced at large angles from the incident beams. The muon …
