Photoproduction of $\Lambda (1405)$ with the two-pole structure

Seung-il Nam, Hyun-Kyu Jo

We investigate the $\Lambda (1405,1/2^{-})\equiv {\Lambda }^{\ast }$ photoproduction off the proton target, i.e. $\gamma p\to K^{+}{\Lambda }^{\ast }$, considering explicitly its two-pole structure, the higher ($Λ^*_H:\,1430\,\m…
