Kaon and nucleon states with hidden charm

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, $K^*(4307)$, which is dynamically generated from the three-body interactions of the $KD\bar D^*$ system, has a mass around 4307 MeV and quantum numbers $I(J^P) = 1/2 (1^-)$. In the baryonic sector, we predict the existence of $N^*$ states, which are generated from the three-body interactions of the $ND\bar D^*$ system, with masses around 4400∼4600 MeV, widths of 2 ∼20 MeV and positive parity.
