SIGMA HYPERON PRODUCTION IN 2- AND 3-BODY FINAL STATES

We find the final states I+K+ and I+K*+ to be produced peripherally with evidence, in both cases, for a small backward peak. The forward differential cross sections for both reactions are compared with the predictions of a Regge-pole model. For I+K*+ we find that the angular correlations in the resonance decay are predicted quite well by an absorptive peripheral model although the model is unable to account for the production angular distribution. © 1968 The American Physical Society.
