Query: A New Experiment to Study Hyperon CP Violation, Charmonium, and Charm   Fermilab operates the world's most intense antiproton source, now exclusively
dedicated to serving the needs of the Tevatron Collider. The anticipated 2009
shutdown of the Tevatron presents the opportunity for world-leading low- and
medium-energy antiproton programs. We summarize the status of the Fermilab
antiproton facility and review physics topics for which a future experiment
could make the world's best measurements.
