CP Violation in $\Lambda$ to p ${\pi }^{-}$: SM vs New Physics

Abstract

I discuss CP violation in $\Lambda$ to p ${\pi }^{-}$ comparing the standard model expectations with what could happen in new physics scenarios. I point out that Fermilab experiment E871 is sensitive to some of these scenarios.
