In 2009, the BESIII experiment has collected about 225M $jpsi$ and 106M $psip$ samples, both of which are the world largest on-peak charmonium production. Based on these dataset, BESIII has made great effort on the study of the charmonium decays, some important of which have been reviewed in this proceeding. In addition, a searching for new physics through the $CP/P$ violation process is reported.
Recent results on Charmonium decays are reviewed which includes two-, three- and four-body decays of $chi_{cJ}$ states, observations of Y(4260) through $pipi J/psi$ transitions, precise measurements of $M(D^0)$, $M(eta)$ as well as $mathcal{B}(etato X)$.
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 charmon
Based on $psi(3686)$ decays of 106 million, the 1.31 billion J/psi events and a data sample of $psi(3770)$ with $2.9~fb^{-1}$ integrated luminosity, many analyses are performed. Exclusively baryonic decays of the $psi(3770)$, the radiative transition
While the charmonium model has been effective in describing ccbar bound mesons, there have been many recently discovered charmonium-like states it cannot accommodate. Here I provide a review of recent results from the B-factories including the X(3872
BESIII experiment has collected about 20 fb$^{-1}$ luminosity data between $sqrt{s}=3.8$ and 4.7 GeV via $e^{+}e^{-}$ collision. In this talk, we present the recent $XYZ$ results at BESIII, including mass and width measurements of $Y(4220)$, search f
