Kaon, Nucleon and ${\Delta }^{\ast }$ Resonances with Hidden Charm

Abstract

In this presentation we discuss the generation of hadrons with an exotic quark content and hidden charm emerging from three-body interactions. To be more specific, we have studied the $KD{\bar{D}}^{\ast }/K\bar{D}{D}^{\ast }$ and $ND{\bar{D}}^{\ast }/N\bar{D}{D}^{\ast }$ systems and predicted states generated from the respective three-body dynamics. In the case of the $KD{\bar{D}}^{\ast }/K\bar{D}{D}^{\ast }$ system we predict the formation of a meson state with mass around $4307$ MeV and quantum numbers $I(J^P)=1/2(1^{-})$, $K^{\ast }(4307)$, and from the study of the $ND{\bar{D}}^{\ast }/N\bar{D}{D}^{\ast }$ system we found $N^{\ast }$ states with masses in the range $4400\sim 4600$ MeV, width of $2\sim 20$ MeV and positive parity.
