Abstract
Motivated by the Belle Collaboration's new observation of , we investigate the possibility of its configuration as a -wave tetraquark state from QCD sum rules. Eventually, the extracted mass for the -wave -scalar-diquark -scalar-antidiquark state agrees well with the experimental data of , which could support its interpretation as a -wave scalar-scalar tetraquark state.
