Abstract

We report final results on prompt electron production in hadronic events from e+e- annihilations at s =29 GeV, obtained with the DELCO detector at the SLAC storage ring PEP. We find the semielectronic branching ratios of charm and bottom quarks to be B(cse+e)=(11.6-0.9 +1.1)% and B(bce-e)=(14.9-1.9 +2.2)% respectively. These results, from the complete data set, are consistent with an earlier analysis of partial data and indicate hard fragmentation functions for both c and b quarks, with mean values zc=0.590.04 and zb=0.720.05. The errors indicated here are a combination of statistical and systematic uncertainties.
