Available in PDF, EPUB and Kindle. Book excerpt: The CDF and D0 collaborations each have collected over 110 pb−1 from top quark physics and searches for first generation leptoquarks (LQ), using the entire statistics of these large data sets. After careful selection, both collaborations have collected top quark data samples consisting of several dozen events each. From these events both experiments have measured the top quark mass and pair production cross section in a variety of decay channels, including the so-called dilepton, lepton plus jets, and all jets channels. The combined top quark mass from both experiments in the lepton plus jets channels is m{sub t} = 175.6±5.5 GeV/c2. CDF and D0 have also performed optimized searches for the pair production of first generation leptoquarks. No candidate events were found. Combining the results from the ee+jets, e?+jets, and??+jets channels both experiments set 95% confidence level (CL) upper limits on the LQ pair production cross section as a function of mass and of?, the branching fraction to a charged lepton.
