Partial wave analysis of $J/\psi \to \gamma \eta \eta$

Based on a sample of 2.25×108 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), f2′(1525), f2(1810) and f2(2340). The resonance parameters and branching fractions are also presented.
