Direct Antiboson-Boson Production in Antiproton - Collisions at SQRT.S = 1.8 Tev

The first measurement of bottom quark production in the forward detector at CDF is presented in this thesis. Events from the 1988/89 Fermilab collider run were selected with forward muons with nearby jets to form a bottom quark tag. The efficiency and acceptance of the detector are then taken into account and the number of events is turned into a cross section: sigma(p_sp{t} {b}>20 GeV, 1.9<|eta ^{b}|<2.5) = (124. +/- 35. +/- 76.) nb. The contribution from direct bottom quarks is sigma(p _sp{t}{b}>20 GeV, p _sp{t}{| b}>15 GeV, 1.9<|eta^{b} |<2.5) = (100. +/- 30._sp{-31.}{+30.}) nb.
