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