摘要By using an effective Lagrangian method, we study the effects of a newly proposed Sigma*(1/2(-)) state with mass around 1380 MeV in the initial-state polarized gamma N -> K+Sigma*(1385) -> K+pi Lambda process near threshold. The theoretical predictions for the helicity cross sections sigma(3/2), sigma(1/2), as well as their ratios, and the angular distributions of pi in the pi Lambda center-of-mass system are given. It is found that assuming Sigma*(1/2(-)) exists or not, these physical quantities are distinctly different. So our results could be useful for the investigation of the existence of Sigma*(1/2(-)) when the experimental data are available in the future.
