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 …

A measurement of the antiproton proton going to antilambda baryon lambda baryon and antiproton proon going to antisigma 0 lambda plus c.c. reactions at 1.726 GeV/c
… were investigated at an average antiproton momentum of 1.726 $\pm$ 0.001 GeV/c using the Low Energy Antiproton Ring (LEAR) at CERN. Total and differential cross sections, hyperon polarizations, and spin correlation coefficients were measured for these strangeness production …

Search for magnetic monopoles possibly produced by proton-antiproton collisions at the Tevatron collider.
… they could have been produced by the proton-antiproton collisions at the Tevatron collider---the highest energy accelerator existing in the world, and trapped in the CDF and DO detectors. We took Al, Be, and Pb samples from the Tevatron and used the induction technique with SQUIDs …

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 …
