-wave fully charmed tetraquark resonant states

Wang, G.-J.*; Meng, Q.*; Oka, Makoto

-wave resonances in the fully charmed tetraquark system are studied in the quark model. The complex scaling method allows us to get the complex eigen-energies of the tetraquark system above the fall-apart decay thresholds. We found two resonances in each of the $J^{PC}=0^{++}$ , $1^{+-}$ and $2^{++}$ sectors, respectively. The obtained resonances are about 100 MeV higher than the recently found resonance, .
