Analysis of the X(6600), X(6900), X(7300) and related tetraquark states with the QCD sum rules

In this work, we re-investigate the mass spectrum of ground state, first, second and third radial excited states diquark-antidiquark type fully-charm tetraquark with QCD sum rules plus Regge trajectories. We take account CMS ATLAS experimental data preform a self-consistent analysis, then try to make possible assignments $X(6600)$, $X(6900)$ $X(7300)$ in picture $J^{PC}=0^{++}$ or $1^{+-}$.
