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 thec andb quarks are (9.1±0.9 (stat.)±1.3 (syst.))% and (11.0±1.8±1.0)%, respectively. Theb quark fragmentation function peaks at highz with 〈z b 〉=0.74±0.05±0.03. The axial couplings to the neutral current area c =2.3±1.4±1.0 for thec quark anda b =−2.0±1.9±0.5 for theb quark.
