Semileptonic decays of bottom baryons at LEP

Technical Report:

Abstract

We study semileptonic {Lambda}{sub b} decays where the {Lambda}{sub b} originates from Z{sub o} decays into b quarks. The differential decay distributions are calculated using the heavy quark effective theory. We investigate the energy distribution of the decay leptons. In {Lambda}{sub b} decays the lepton energy distribution is sensitive to the standard model parameters via the nontrivial {Lambda}{sub b} polarization. We also discuss a possibility to study b quark fragmentation into baryons using the semileptonic decays. (orig.).
