The ratios RJ(P)Γ(J)→P+P-), P = π or K, have been evaluated ad due to contact interactions genrated by gauge invariance, for mesons with natural JP. RJ increases rapidly with J. This provides unambigous tests for the model and indicates that contact terms are prolific sources of photons and leptons in hadron collisions. © 1979.
