dc.description.abstract We study the coupling of the Λ(1520)≡Λ* resonance to the K* vector meson and nucleon. This coupling is not directly measured from the resonance decay, but is expected to be important in hyperon production reactions, in particular for the exotic Θ+ production. We compute the coupling in two different schemes, one in the chiral unitary model where the Λ* is dominated by the quasibound state of mesons and baryons, and the other in the quark model where the resonance is a p-wave excitation in the three valence quarks. Although it is possible to construct both models such that they reproduce the KN and πΣ decays, there is a significant difference between the Λ*K*N couplings in the two models. In the chiral unitary model gΛ*K*N∼1.5, while in the quark model gΛ*K*N∼10. The difference of the results stems from the different structure of the Λ* in both models, and hence, an experimental determination of this coupling would shed light on the nature of the resonance
