$N^*$ states with hidden charm and a three-body nature


الملخص بالإنكليزية

In this work we study the formation of $N^*$s as a consequence of the dynamics involved in the $NDbar D^*-Nbar D D^*$ system when the $Dbar D^*-bar D D^*$ subsystem generates $X(3872)$ in isospin 0 and $Z_c(3900)$ in isospin 1. States with isospin $I=1/2$ and mass in the energy region $4400-4600$ MeV are obtained with spin-parity $J^P=1/2^+$ and $3/2^+$, predicting in this way the existence of $N^*$ resonances with hidden charm and a three-body nature.
