Latest results from the MARK II at PEP
Description
Single photon annihilation results from the MARK II detector at PEP based on approx. 100 pb-1 of integrated liminosity taken at a center of mass energy root 8 = 29 GeV are presented. A study of inclusive leptons for momenta greater than or equal to 2 GeV/c yield the average semileptonic branching ratios of bottom (b) and charm (c) quarks and information about the b fragmentation function. A measurement of the bottom hadron lifetime is presented based on a study of the prompt lepton impact parameters. In addition a precise measurement of the tau life time and a updated D0 lifetime are reported. A search for supersymmetric electrons, weak neutral current couplings from leptons and bottom particles and evidence for K/sup */'s at PEP are also presented
