Description

The three narrow $P_c$ 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 various reactions, such as γp → ϕp, γp → K$\Lambda$, γp → KΣ, γp → KΣ*, γp → KΣ, pp → pK$\Lambda$, $J/\psi\to K_S\bar n\Lambda$+c.c., $\chi_{c0}\to\bar pK^{*+}\Lambda$+c.c. , etc., which give clear supports of the existence of the strange molecular partners of $P_c$ states. More production processes of these $N^*$ resonances with hidden strangeness are proposed to further test the hadronic molecular picture.
