Prospects for low-energy antiproton physics at Fermilab

Abstract

Fermilab has long had the world's most intense antiproton source, but the opportunities for medium-energy antiproton physics have been limited, and those for low-energy antiproton physics nonexistent. The conclusion of E835 brings this era to an end. While the future of antiproton physics at Fermilab remains highly uncertain, developments are occurring that may lead to a low-energy program within the next several years, with the possibility of an improved medium-energy program thereafter. These issues were considered at the recent $\bar{p}2000$ Workshop at Illinois Institute of Technology. I summarize the current status of the Fermilab antiproton facility, review hyperon {\em CP} violation as an example of the physics that might be achievable, and discuss future possibilities.
