A possible ${\Sigma }^{\ast }$ or ${\Lambda }^{\ast }$ resonance with $J^P=3/2^{-}$ in $K^{-}p\to K\Xi$ scattering

Zheng-Li Luo, Jia-Jun Wu, Bing-Song Zou

We analyze the $K^{-}p\to K^{+}{\Xi }^{-}$ and $K^{-}p\to K^0{\Xi }^0$ processes in the energy region $1.8<\sqrt{s}<2.8$ GeV within an effective Lagrangian approach. The $\Lambda (1800)$ and $\Sigma (2250)$ reso…
