Searching for strange hidden-charm pentaquark state $P_{cs}(4459)$ in $\gamma p\to K^{+}{P}_{cs}(4459)$ reaction

Cai Cheng, Feng Yang, Yin Huang

We investigate the possibility of studying the strange hidden-charm pentaquark state $P_{cs}(4459)$ by photon-induced reactions on a proton target in an effective Lagrangian approa…
