AbstractWe study the reactions J/psi -> (Lambda) over barK(-)p and J/psi -> (Lambda) over bar pi(+)pi(-)Lambda with a unitary chiral approach. We predict the ratio of the invariant-mass distributions of these two reactions at the Lambda(1520) peak position, which is free of the unknown production mechanism and reflects only the properties of the Lambda(1520). An experimental measurement of this ratio will provide the couplings of the Lambda(1520) to its decay channels, allowing to test the predictions of the chiral unitary approach on this resonance, which appears as dynamically generated in that approach.
