Kaon-induced production of strange hidden-charm molecular pentaquarks $P_{\psi s}^{\Lambda }$ from proton

Shu Chen, Jun-Tao Zhu, Shu-Yi Kong +1

In this work, we investigate the kaon-induced production of strange hidden-charm pentaquark $P_{\psi s}^{\Lambda }$ states, including the $P_{\psi s}^{\Lambda }(4459)$ and $P_{\psi s}^{\Lambda }(4338)$ observed by the L…
