Abstract

The effect on nonleptonic processes of quark-antiquark pairs due to quantum chromodynamics is studied. Their presence improves agreement between theory and experiment for hyperon decays. In kaon decays a new ΔI = 1 2 contribution is found, but Δ = 3 2 effects are still large to to be in agreement.
