Abstract

We report results of the first measurements of Λ and Λ̄ polarization produced in deep inelastic polarized muon scattering on the nucleon. The results are consistent with an expected trend towards positive polarization with increasing cursive Greek chi_F. The polarizations of Λ and Λ̄ appear to have opposite signs. A large negative polarization for Λ at low positive cursive Greek chi_F is observed and is not explained by existing models. A possible interpretation is presented.
