The strange quark plays a crucial role in many aspects of nuclear physics, from its contribution to nucleon form factors, to the production and decay properties of hypernuclei, to possible kaon condensation in neutron stars. The strange quark is distinct from the other quarks in that its mass sits so near that of the typical hadronic scale that it is difficult to treat accurately in any of the known effective theories of QCD. Much remains to be learned about both QCD and electroweak interactions through a study of strangeness.

On-going and planned experiments, at facilities such as those at Brookhaven, CERN, Jülich, Fermilab, the Frascati phi factory, the Jefferson Lab, KEK, and MIT-Bates explore critical aspects of strange physics. This is a particularly opportune time for a Program dedicated to strange physics, where we expect theorists to guide experimentalists working at forthcoming facilities, and experimentalists to guide theorists in understanding and interpreting the latest measurements. We hope to establish interactions among leading scientists in the field of strange physics that will survive to unravel some of the most puzzling aspects in the field.

The "Physics of Strangeness" program is scheduled to run from Monday September 28 (1998) until Friday December 4 (1998).
