Available in PDF, EPUB and Kindle. Book excerpt: We have measured the lifetime of an ensemble of particles containing b quarks, tagged with a high p/sub T/ lepton from their semileptonic decay. Using a method which estimates the production point of each particle in the beam ellipse, we measured a lifetime of 0.98 +- 0.12 +- 0.13 psec. We have also studied methods of partially reconstructing B mesons decaying into D/sup/star//minus// mesons plus charged leptons or mesons. We have searched the Mark II PEP data samples and find five candidates for B° decay. Four of these B° candidates form good vertices, and their measured proper lifetimes are presented. 18 refs.
