Possible ${\Sigma }^{\ast }(1/2^{-})$ in the initial-state polarized $\gamma N\to K^{+}{\Sigma }^{\ast }(1385)\to K^{+}\pi \Lambda$ reaction near threshold

Yun-Hua Chen, Bing-Song Zou

By using an effective Lagrangian method, we study the effects of a newly proposed ${\Sigma }^{\ast }(1/2^{-})$ state with mass around 1380 MeV in the initial-state polarized $γN\rightarrow K^{+} Σ…
