Abstract

Recent results on prompt lepton production from PEP are presented. Measurements are given for the differential cross section of prompt leptons. Semi-leptonic branching ratios and fragmentation functions of charm and bottom quarks are discussed. Preliminary data on the properties of bottom quark jet are reported.
