In this work, the genuine resonance states of full-charm tetraquark systems with quantum numbers JPC=0++,1+−,2++ are searched in a nonrelativistic chiral quark model with the help of the Gaussian Expansion Method. In this calculation, two structures, meson-meson and diquark–antidiquark, as well as their mixing with all possible color-spin configurations, are considered. The results show that no bound states can be formed. However, resonances are possible because of the color structure. The genuine resonances are identified by the stabilization method (real scaling method). Several resonances for the full-charm system are proposed, and some of them are reasonable candidates for the full-charm states recently reported by LHCb.

Starting from the Vlasov–Landau kinetic equation, linearized around the global equilibrium state and assuming the finite dimensional approximation to the non-hydrodynamical subspace, we derive the hydrodynamical equations for a weakly coupled, one-component plasma. Explicit expressions are given for the transport coefficients and frequencies of the hydrodynamical modes. These results describe the influence of the plasma oscillations on the hydrodynamical behaviour of the system. Certain differences are obtained compared with the standard phenomenological approach. Also the real part of the frequency for the plasma mode in our model is in agreement with the Bohm–Gross dispersion relation.
