  Despite measurements which date more than 20 years ago, no straightforward
solution of the ratio of the parity-conserving (P-wave) to parity- violating
(S-wave) decays of the hyperons has been obtained. Here we use two 2-point
methods in QCD sum rules to examine the problem. We find that resonance
contributions are needed to fit the data, similar to a chiral perturbation
theory treatment.
