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

In this work we study the formation of N*'s as a consequence of the dynamics involved in the ND (D) over bar* - N (D) over barD* system when the D (D) over bar* - (D) over barD* 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 found to arise with spin-parity J(P) = 1/2(+) and 3/2(+), thus leading to predictions of the existence of N* resonances with hidden charm and a three-body nature. We also discuss the possibility of the existence of Delta(c) states, i.e., Delta's with hidden charm.

Automated summary

In this work, the formation of N*'s in the ND (D) over bar* - N (D) over barD* system is studied. It is found that states with isospin I = 1/2 and mass in the energy region 4400 - 4600 MeV can arise with spin-parity J(P) = 1/2(+) and 3/2(+), indicating the existence of N* resonances with hidden charm and a three-body nature. The possibility of the existence of Delta(c) states, Delta's with hidden charm, is also discussed.
