\begin{document}$ J^{PC}=0^{++} $\end{document}, \begin{document}$ 0^{-+} $\end{document}, \begin{document}$ 0^{--} $\end{document}, \begin{document}$ 1^{--} $\end{document}, \begin{document}$ 1^{+-} $\end{document}, and \begin{document}$ 1^{++} $\end{document}. The analysis reveals the existence of fully strange tetraquark states with masses ranging from approximately \begin{document}$ 2.07 $\end{document} to \begin{document}$ 3.12 $\end{document} GeV. These predictions are compared with existing experimental observations of potential fully strange tetraquark resonances, notably the \begin{document}$ X(2300) $\end{document} recently reported by the BESIII Collaboration, which may be interpreted as a fully strange tetraquark state. Furthermore, the possible decay modes of these fully strange tetraquark states are analyzed, providing guidance for their identification in current and future high-energy experiments, such as BESIII, Belle II, and LHCb."> Fully strange tetraquark states via QCD sum rules -
