Abstract

BESIII has collected $1.3 \times 1 0^{8} J / ψ$ and $0.4 \times 1 0^{8}$ of $ψ^{'}$ , which are the world’s largest data samples of $J / ψ$ and $ψ^{'}$ from $e^{+} e^{-}$ collision. Radiative decays of charmonium provide a gluon-rich environment and are therefore regarded as one of the most promising hunting grounds for gluonic excitations. Significant progresses in the light-quark sector have been made with the unprecedented high statistics data sets. Several recent results on light hadron spectroscopy and light hadron decays will be reported, including: 1, the observation of the anomalous line shape of $X (1835)$ near $p \bar{p}$ mass threshold and related studies; 2, studies of glueballs in $J / ψ$ radiative decays; 3, search for $1^{- +}$ exotic in $χ_{c 1} \to η π π$ .
