Özet
Using a sample of (10.09±0.04)×109 J/? events collected with the BESIII detector, a partial wave analysis of J/???? ? is performed. The masses and widths of the observed resonances and their branching fractions are reported. The main contribution is from J/???f0(2020) with f0(2020)?? ? , which is found with a significance of greater than 25?. The product branching fraction B(J/???f0(2020)) B(f0(2020)?? ? ) is measured to be (2.63±0.06(stat.)+0.31-0.46(syst.))×10-4. © 2022 American Physical Society. All rights reserved.
