Description

Abstract: I will review what my collaboration groups found on N with hidden strangeness in γp → KΛ, γp → KΣ, γp → KΣ, γp → KΣ, and their open strange partners in KLp→π+Σ0, K−p → KΞ reactions inn last two years. More production processes of the penta-quark states with strangeness are proposed to further test the hadronic molecular picture.
