    Abstract

    We have measured the inclusive prompt electron cross section over a wide momentum range (P>0.5 GeV/c) with the PEP-4 TPC detector. The semielectronic branching fractions of the c and b quarks are (9.1±0.9 (stat.)±1.3 (syst.))% and (11.0±1.8±1.0)%, respectively. The b quark fragmentation function peaks at high z with 〈zb〉=0.74±0.05±0.03. The axial couplings to the neutral current are ac=2.3±1.4±1.0 for the c quark and ab=-2.0±1.9±0.5 for the b quark.
