CP Violation in Hyperon Decays from SUSY with Hermitian Yukawa and A Matrices

Abstract

We show that a large CP asymmetry in hyperon decays can be naturally realized in the framework of SUSY models. The possibility is implemented by the hermiticities of Yukawa and A matrices. And also, the observed values of $\epsilon$ and ${\epsilon }^{\prime }$ are explained.
