Kaon-induced production of strange hidden-charm molecular pentaquarks
$P^\Lambda_{\psi s}$ from proton
In this work, we investigate the kaon-induced production of strange hidden-charm pentaquark $P^\Lambda_{\psi s}$ states, including the $P^\Lambda_{\psi s}(4459)$ and $P^\Lambda_{\psi s}(4338)$ observed by the LHCb collaboration. Coupled-channel interactions involving the channels $\bar{K}N$, $\Xi_c^{(*)}\bar{D}^{(*)}$, $\Xi'_c\bar{D}^{(*)}$, $\Lambda_c\bar{D}_s^{(*)}$, and $\Lambda J/\psi$ are studied using effective Lagrangians to describe these interactions. The potential …
