Description
The three narrow Pc states decaying to J/ψp observed by the LHCb experiment are consistent with earlier predictions for one $\bar D\Sigma_c$ and two $\bar D^*\Sigma_c$ bound states. Their strange partners are expected to exist. Here we present evidence for the production of these N resonances with hidden strangeness in $\gamma p$ reactions, such as γp → ϕp, γp → KΣ, γp → KΣ, γp → KΣ, etc., which give clear supports of the existence of the strange molecular partners of Pc states. More production processes of these N resonances with hidden strangeness are proposed to further test the hadronic molecular picture.
