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.

The conference focused on the current status of baryon spectroscopy, form factors and structure functions, electroweak interactions and symmetries, strange and exotic states, chiral perturbation theory, heavy quark physics, and medium modifications, through plenary session summaries and reviews and parallel session reports of recent experimental and theoretical advances. Plans for future facilities and upgrades were highlighted in special plenary sessions.
