Abstract

We conduct the first comprehensive P-wave four-body dynamical calculations of the fully charmed tetraquark systems within the quark potential model. We apply the Gaussian expansion method to solve the four-body Schr\"odinger equation, incorporating both dimeson and diquark-antidiquark spatial configurations. The matrix elements of P-wave states are calculated analytically using the infinitesimally-shifted Gaussian basis functions. With the complex scaling method, we obtain several fully charmed P-wave resonant states with compact tetraquark configuration in the mass region of (7.0,7.2)(7.0,7.2) GeV, including states with exotic quantum numbers JPC=0,1+J^{PC}=0^{--},1^{-+}. However, we find no resonant states with the mass M<7M<7 GeV and width Γ<200\Gamma<200 MeV. Combining the present investigation with our previous results on S-wave fully charmed tetraquark systems, we find no candidates for the experimental states X(6400)X(6400) and X(6600)X(6600) in the quark model.
