Findings

Predicted a meson state at 4307 MeV with specific quantum numbers.

Identified N* states with masses between 4400 and 4600 MeV.

Estimated widths of the N* states between 2 and 20 MeV.

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 $KD\bar{D}^*/K\bar D D^*$ and $ND\bar{D}^*/N\bar{D}D^*$ systems and predicted states generated from the respective three-body dynamics. In the case of the $KD\bar{D}^*/K\bar D D^*$ system we predict the formation of a meson state with mass around $4307$ MeV and quantum numbers $I(J^P) = 1/2(1^-)$, $K^*(4307)$, and from the study of the $ND\bar{D}^*/N\bar{D}D^*$ system we found $N^*$ states with masses in the range $4400\sim 4600$ MeV, width of $2\sim 20$ MeV and positive parity.
