Studies of Charmonium at BESIII

Abstract

In recent years, lots of studies of charmonium decays have been performed at BESIII based on large data samples of $J/\psi$, $\psi (3686)$ and $\psi (3770)$. Recent results in searches for radiative transitions of $\psi (3770)$ and rare phenomena in charmonium decays, and studies of light hadrons structures and properties will be presented.
