英文摘要	In this work the roles of the nucleon resonances in the Lambda(1520) photoproduction off a proton target are investigated within the effective Lagrangian method. Besides the Born terms, including the contact term and s, u, and K exchanged t channels, the vector meson K* exchanged t channel is considered in our investigation, which is negligible at low energy and important at high energy. The important nucleon resonances predicted by the constituent quark model (CQM) are considered and the results are found to be well comparable with the experimental data. Besides the dominant D-13(2080), the resonance [5/2(-)](2)(2080) predicted by the CQM is found to be important for reproducing the experimental data. Other nucleon resonances are found to give small contributions in the channel considered in this work. With all important nucleon resonances predicted by the CQM, the prediction of the differential cross section at an energy up to 5.5 GeV is presented also; this can be checked by future CLAS experimental data.
