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

Based on a sample of $2.25\times {10}^8$ $J\mathrm{/}\psi$ events collected with the BESIII detector at BEPCII, a full partial wave analysis on $J\mathrm{/}\psi \to \gamma \eta \eta$ was performed using the relativistic covariant tensor amplitude method. The results show that the dominant $0^{++}$ and $2^{++}$ components are from the $f_0(1710)$, $f_0(2100)$, $f_0(1500)$, $f_2^{\mathrm{\prime }}(1525)$, $f_2(1810)$ and $f_2(2340)$. The resonance parameters and branching fractions are also presented.
