英文摘要	Based on the experimental data released recently by the CLAS Collaboration, the f(1)(1285) photoproduction off a proton target is investigated in an effective Lagrangian approach. In our model, s-channel, u-channel, and t-channel Born terms are included to calculate the differential cross sections, which are compared with the recent CLAS experiment. An interpolating Reggeized treatment is applied to the t channel, and it is found that the t-channel contribution is dominant in the f(1)(1285) photoproduction and the u-channel contribution is responsible for the enhancement at backward angles. The present calculation does not take into account any explicit s-channel nucleon-resonance contribution; nevertheless, our model provides a good description of the main features of the data. It suggests small couplings of the f(1)(1285) and the nucleon resonances in this energy region.
