| 英文摘要 | The LEPS Collaboration has recently reported a measurement of the gamma n -> K+Sigma*(-)(1385) reaction using a linearly polarized photon beam around the resonance region. The observed beam asymmetry is sizably negative at E-gamma = 1.8-2.4 GeV, in contrast to the presented theoretical prediction. In this paper, we calculate this process using the framework of the effective Lagrangian approach. By including a newly proposed Sigma(J(P) = 1/2(-)) state with a mass around 1380 MeV, the experimental data for both gamma n and gamma p experiments can be well reproduced. It is found that the Sigma(1/2(-)) and/or the contact term may play an important role and may deserve further investigation. |
