Measurement of the B hadron energy distribution in Z0 decays
Abstract
We have measured the B hadron energy distribution in Z0 decays using a sample of semileptonic B decays recorded in the SLD experiment at SLAC. The energy of each tagged B hadron was reconstructed using information from the lepton and a partially reconstructed charm-decay vertex. We compared the scaled energy distribution with several models of heavy quark fragmentation. The average scaled energy of primary B hadrons was found to be <xEB>=0.716+/-0.011(stat)+0.021-0.022(syst).
