Kaon and Nucleon States with Hidden Charm

Abstract

In this talk we discuss the formation of exotic hadrons with hidden charm arising from three-body interactions. To be more specific, in the strangeness sector, we predict the existence of a mesonic state, $K^{\ast }(4307)$, which is dynamically generated from the three-body interactions of the $KD{\bar{D}}^{\ast }$ system, has mass around $4307$ MeV and quantum numbers $I(J^P)=1/2(1^{-})$. In the baryonic sector, we predict the existence of $N^{\ast }$ states, which are generated from the three-body interactions of the $ND{\bar{D}}^{\ast }$ system, with masses around $4400\sim 4600$ MeV, widths of $2\sim 20$ MeV and positive parity.
