摘要：

Data on the nucleon spin structure suggests that the u- (and d-) quark distributions in the Lambda hyperon may be polarized. If this correlation carries over into fragmentation, then the study of polarized Lambda's in the current fragmentation region of deep inelastic lepton scattering will be a sensitive probe of the nucleon spin structure. Lambda production by polarized electrons from unpolarized targets can search for this correlation. If it is significant, Lambda production by unpolarized electrons from longitudinally and transversely polarized targets can probe the u-quark helicity and transversity distributions in the nucleon.
