Inclusive Electron Production from Heavy Quarks with the Tasso Lead-Liquid Argon Calorimeters in Electron Positron Annihilation at PETRA

The production of electrons from the decay of bottom and charm hadrons has been studied in e('+)e('-) annihilation at 34.6 GeV center of mass energy using lead -liquid argon calorimeters. It is observed that the b quark fragmentation function is peaked at large values of the scaling variable z with. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). For c quarks. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). is observed. A forward-backward charge asymmetry of A = -0.25 (+OR-) 0.22 was measured in b production. As the calorimeters and the methods of pattern recognition are well suited to (pi)('0) identification, the inclusive (pi)('0) cross section has also been measured.
