This workshop gives an overview of the physics opportunities that would be created by high-quality, intense pion beams with energies up to about 1 GeV. Topics explored include hypernuclear structure studies using the (π,K) reaction, hyperon–nucleon scattering including polarization, high-energy pion–nucleus reactions such as absorption and double charge exchange, baryon–resonance investigations, and decays of the π and h mesons. The present status of high-energy pion beamlines and instrumentation as well as new directions in the field were also discussed.

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.
