摘要：

We study semileptonic LAMBDA(b) decays where the LAMBDA(b) originates from Z0 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(b) decays the lepton energy distribution is sensitive to the standard model parameters via the nontrivial LAMBDA(b) polarization, We also discuss a possibility to study b quark fragmentation into baryons using the semileptonic decays.
