Description

BESIII has the world’s largest samples of $J/\psi$ and $\psi (3686)$ events from
$e^{+}{e}^{-}$annihilations, which offer an ideal and clean laboratory to study light meson
spectroscopy , in particular for the search for QCD exotics. Recent important
achievements in this field, including the observation of a 1-+ state, ${\eta }_1(1855)$ in
$J/\psi ->\gamma \eta {\eta }^{\prime }$, the observation of the $X(2600)$ in $J/\psi ->\gamma {\eta }^{\prime }{\pi }^{+}{\pi }^{-}$,
and the PWA of $J/\psi ->\gamma {\eta }^{\prime }{\eta }^{\prime }$ will be highlighted.
