| 英文摘要 | The differential cross-section data from the CLAS Collaboration for gamma p -> K*(+) Lambda have been analyzed based on an effective Lagrangian approach. The t-channel K, kappa, K* exchanges, the s-channel N and near-threshold N-*'s exchanges, the u-channel Lambda, Sigma, Sigma*(1385) exchanges, and the generalized contact term are considered in constructing the reaction amplitude. It is found that by including the N (2060)5/2(-) resonance, which is responsible for the shape of the angular distribution of gamma p -> K*(+) Lambda near the K*Lambda threshold, and one of the N(2000)5/2(+), N(2040)3/2(+), N(2100)1/2(+), N(2120)3/2(-) and N (2190)7/2(-) resonances, one can describe the cross-section data for this reaction reasonably well. More experimental data on spin observables are needed to further pin down the resonance contents and associated resonance parameters in this reaction. |
