· Physical Review. D.
Based on events collected with the BESIII detector operating at the BEPCII collider, a partial wave analysis of the decay is performed. We observe for the first time two new structures on the invariant mass distribution, with significances exceeding and ; the first with , mass , and width , the second with , mass , and width . These measurements provide important input for the strangeonium spectrum. In addition, the mixing signal in and the corresponding electromagnetic decay are measured with improved precision, providing crucial information to understand the nature of and .
