Summary:A structure called was observed in the process, where , by the Belle Collaboration in 2019. This resonance can be interpreted as a compact state with a dominant tetraquark component. The mass eigenstate is treated as a linear combination of the diquark-antidiquark and components due to the mixing via gluonic exchanges, and a mixing angle between them can be estimated from electronic widths. This mixing provides a mechanism for the production in high energy collisions through its component, and the Drell–Yan and prompt production cross sections for the process at the LHC are worked out. Present experimental status of the -resonance is also discussed.
