Abstract

The BESIII experiment has collected world's largest direct $e^+e^-$ colliding beam data at the $J/\psi$, $\psi'$, $\psi$(3770) and at and around the $Y$(4260). These data have enabled the study of hadrons at unprecedented precisions. We present results on the light hadron spectroscopy, production of hadrons in radiative decays of charmonia, observation of new excited $N^*$ baryons and of anomalous decays of the $\eta/\eta'$ states.
