Should $\bar{p}p\to \bar{\Lambda }\Lambda$ be revived?

Abstract

The continued interest of CP violation in hyperon decay (as well as many other physics topics that could be addressed by such a facility) suggests that a dedicated $\bar{p}$ storage ring at Fermilab ought to be reconsidered. With recent and anticipated technical progress, sensitivity many orders of magnitude beyond that achieved in LEAR may be possible, including 10^{-5} sensitivity for the $\Lambda /\bar{\Lambda }$ CP-asymmetry parameter $A_{\Lambda }$.
