abstract

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

  1. On the nature of fully-charmed four-quark exotic state $X(6900)$ from its photoproduction off nuclei

    hep-ph 2026-08 conditional novelty 5.0 of 10

    Nuclear photoproduction of X(6900) off carbon and tungsten is predicted to differ by 10-30% between compact-tetraquark, J/psi-psi(3770) molecular, and hybrid interpretations, potentially allowing future electron-ion c...

    hep-ph 2026-07 unverdicted novelty 5.0 of 10

    Symmetry analysis of compact tetraquarks shows low-energy states favor J^P=2+ and places X(6600), X(6900), X(7100) among the lower levels of the fully charmed spectrum.

  3. A novel configuration of gluonic tetraquark state

    hep-ph 2024-11 conditional novelty 5.0 of 10

    The predicted masses of the octet-octet-octet tetracharm hybrid states, 6.98 GeV (0++) and 7.26 GeV (0-+), overlap the observed X(6900) and X(7200).
