Description
The cross section for the process is measured precisely at center-of-mass energies from 3.77 to 4.60 GeV using of data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant structures are observed in a fit to the cross section. The first resonance has a mass of and a width of , while the second one has a mass of and a width of , where the first errors are statistical and second ones are systematic. The first resonance agrees with the resonance reported by previous experiments. The precision of its resonant parameters is improved significantly. The second resonance is observed in for the first time. The statistical significance of this resonance is estimated to be larger than . The mass and width of the second resonance agree with the resonance …
