| The Λ(1520) resonance has been recently studied in a unitarized coupled channel formalism with πΣ(1385), KΞ(1530), K¯N and πΣ as constituents blocks. We provide a theoretical study of the predictions of this model in physical observables of the pp→pK+K−p and pp→pK+π0π0Λ reactions. In particular, we show that the ratio between the π0π0Λ and K−p mass distributions can provide valuable information on the ratio of the couplings of the Λ(1520) resonance to πΣ(1385) and K¯N that the theory predicts. Calculations are done for energies which are accessible in an experimental facility like COSY at J\'ulich or the developing CSR facility at Lanzhou. | |||
