Theoretical study of the $\Lambda$(1520) photoproduction off proton target based on the new CLAS data

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.
