We present a detailed study of the partial decay widths of a spin-parity resonance JP = 3/2-N* with a mass of <^>2070 MeV obtained from the coupled channel s-wave vector-baryon pN, wN, %N, K*A, and K*E dynamics. This state, which couples strongly to the K*E channel, corresponds to a nucleon with a hidden strange quark content, in analogy to the Pc states discovered by the LHCb Collaboration, and we denote it as Ps(2080). A state with such a nature can decay to vector-baryon, pseudoscalar-baryon, and pseudoscalar-baryon resonance channels, involving triangular loops in the latter two cases. As we will show, the partial decay widths to pseudoscalar-baryon resonance channels, like ,TN*(1535), ,TN*(1650), KA(1405), are comparable to those related to ground state baryons in the final state, like ,TN, rlN, KA. In this way, reactions involving such lighter baryon resonances in the final state can be used as an alternative source of information on the properties of an N* with hidden strangeness. (AU) | |
