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 …

Design Of A High Luminosity 100 Tev Proton Antiproton Collider
… scale. 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 …

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 …

Direct Measurement of the W Boson Decay Width in Proton-Antiproton Collisions at sqrt(s)=1.96 TeV
This dissertation describes a direct measurement of the W boson total decay width, using the DZero detector at the Fermilab Tevatron Collider. The measurement uses an integrated luminosity of 177.3 pb-1 data, collected during the 2002-2003 run. The width is determined from the shape of the …

A Measurement of B Hadron Correlations in Proton-Antiproton Collisions at Center of Mass Energy = 1.8 TeV
B hadron correlations provide input into the significance of higher-order bb¯ production mechanisms. We present a study of B hadron correlations in pp¯ collisions at s = 1.8 TeV. Events containing a bb¯ pair are identified by the presence of an energetic electron or muon and both B …
