Study of $\chi_{cJ}\to \eta \eta \eta^\prime$ via intermediate charmed meson loop mechanisms and its implications for non-observation of $\eta_1(1855)$ in $\chi_{cJ}$ decays
Charmed-meson loop calculations reproduce the branching fractions of chi_cJ to eta eta eta' and the absence of eta1(1855) signal in the eta eta' spectrum.
