Based on a sample of 2.25 × 10 8 J/ψ events collected with the BESIII detector at BEPCII, a full partial wave analysis on J/ψ → γηη was performed using the relativistic covariant tensor amplitude method. The results show that the dominant 0 ++ and 2 ++ components are from the f0(1710), f0(2100), f0(1500), f ′ 2 (1525), f2(1810) and f2(2340). The resonance parameters and branching fractions are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
