    Abstract

    We have studied the production of prompt muons in hadronic events from e+e- annihilation at a center-of-mass energy of 29 GeV with the PEP4-TPC (Time Projection Chamber) detector. The muon p and pt distributions are well described by a combination of bottom- and charm-quark decays, with fitted semimuonic branching fractions of (15.21.91.2)% and (6.91.11.1)%, respectively. The muon spectra imply hard fragmentation functions for both b and c quarks, with z(b quark)=0.800.050.05 and z(c quark)=0.600.060.04. We derive neutral-current axial-vector couplings of a(b quark)=-0.91.10.3 and a(c quark)=1.51.50.5 from the forward-backward asymmetries.
