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 KDDˉ/KDˉDKD\bar{D}^*/K\bar D D^* and NDDˉ/NDˉDND\bar{D}^*/N\bar{D}D^* systems and predicted states generated from the respective three-body dynamics. In the case of the KDDˉ/KDˉDKD\bar{D}^*/K\bar D D^* system we predict the formation of a meson state with mass around 43074307 MeV and quantum numbers I(JP)=1/2(1)I(J^P) = 1/2(1^-), K(4307)K^*(4307), and from the study of the NDDˉ/NDˉDND\bar{D}^*/N\bar{D}D^* system we found NN^* states with masses in the range 440046004400\sim 4600 MeV, width of 2202\sim 20 MeV and positive parity.
