It was pointed out recently that supersymmetry can generate flavor-changing gluonic dipole operators with sufficiently large coefficients to dominate the observed value of epsilon'/epsilon. We point out that the same operators contribute to direct CP violation in hyperon decay and can generate a CP violating asymmetry A(\Lambda^0_-) in the range probed by the current E871 experiment. Interestingly, models that naturally reproduce the relation lambda = sqrt{m_d/m_s} do not generate epsilon'/epsilon but could lead to an A(\Lambda^0_-) of O(10^{-3}).

CP violation in $\Sigma^+\to p\ell^+\ell^-$ within the standard model and beyond
The CP-violating decay-rate asymmetry in Σ⁺→pℓ⁺ℓ⁻ is allowed to reach tens of percent and is testable at LHCb.
