Exotic states with triple charm

In this work we investigate the possibility of the formation of states from the dynamics involved in the D* D* D* system by considering that two D*'s generate a JP = 1+ bound state, with isospin 0, which has been predicted in an earlier theoretical work. We solve the Faddeev equations for this system within the fixed center approximation and find the existence of J(P) = 0(-), 1(-) and 2(-) states with charm 3, isospin 1/2, masses similar to 6000 MeV, which are manifestly exotic hadrons, i.e., with a multiquark inner structure.

Automated summary

This study investigates the possibility of the formation of exotic hadrons in the D* D* D* system. It is found that two D*'s can generate a bound state with JP = 1+, isospin 0. By solving the Faddeev equations within the fixed center approximation, states with J(P) = 0(-), 1(-), and 2(-) are discovered, which have charm 3, isospin 1/2, and masses around 6000 MeV, indicating their multiquark inner structure.
