Description

The three narrow Pc states decaying to J/ψp observed by the LHCb experiment are consistent with earlier predictions for one D¯Σc and two D¯Σc 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 → KΛ, γp → KΣ, γp → KΣ*, γp → KΣ, pp → pKΛ, J/ψKSn¯Λ+c.c., χc0p¯K+Λ+c.c. , 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.
