Early experiments at Fermilab observed significant polarization of inclusively produced hyperons. these and subsequent experiments showed that?° were produced polarized while {bar {Lambda}}° had no polarization in the same kinematical region. Other hyperons and antihyperons were also seen to be polarized. Recent Fermilab experiments have showed this to be a rich and complex phenomena. Theoretical understanding is still lacking. Fermilab E761 has shown that bent single crystals can be used to process the polarization of hyperons and from the precession angle measure the hyperons̀ magnetic moment. This opens the possibility of measuring the magnetic moments of charmed baryons. Finally, I will briefly discuss Fermilab E781, an experiment designed to study charmed particle production by? − hyperons.

This seminar focusses on the key issues addressed in measuring the hyperon-nucleon strong and weak interaction observables and in modelling the hyperon-nucleon interaction. Both quark and baryon pictures are addressed. Results from recent experiments at BNL, KEK, CERN and FNAL, including hyperon production, polarization and decay, are explored; both S = -1 and S = -2 systems are included. The status of our understanding of hyperon weak decays in the nuclear medium is examined and the constraints placed upon our modelling of the hyperon-nucleon interaction by our knowledge of hypernuclear properties are also investigated. Finally, the present status of, as well as future prospects for, the measurements of the hyperon-nucleon interaction are summarized.

The fact that inclusively produced hyperons are produced with significant polarization was first discovered at Fermilab about seventeen years ago. This and subsequent experiments showed that [Lambda][degree] were produced polarized while [bar [Lambda] [degree]] had no polarization in the same kinematical region. This set the stage for many experiments which showed that most hyperons are produced polarized. Recent Fermilab experiments have showed that this phenomena is even more complex than previously thought and theoretical understanding is still lacking. Nevertheless polarized hyperon beams have been an extremely useful experimental tool in measuring hyperon magnetic moments and hyperon [beta]-decay. Recently, hyperon radiative decays have been studied and magnetic moment precession of channeled particles in bent crystals has been observed.
