英文摘要: Based on the high precision experimental data released by the CLAS Collaboration recently, the interaction mechanism of the photoproduction of Lambda(1520) off a proton target is investigated within a Regge-plus-resonance approach. With the decay amplitudes predicted in the constituent quark model, the roles played by nucleon resonances are studied. It is found that N(2120) provides the most important contribution among the nucleon resonances predicted in the constituent quark model. The t channel contribution with Regge trajectories and the Lambda intermediate u channel are responsible to the behaviors of the differential cross section at forward and backward angles, respectively.
