Abstract
It was pointed out recently that supersymmetry can generate flavor-changing gluonic dipole operators with sufficiently large coefficients to dominate the observed value of ε′/ε. We point out that the same operators contribute to direct CP violation in hyperon decay and can generate a CP violating asymmetry A(Λ_0) in the range probed by the current E871 experiment. Interestingly, models that naturally reproduce the relation λ = md/ms do not generate ε′/ε but could lead to an A(Λ_0) of O(10-3). ©2000 The American Physical Society.
