Study of Charmonium(-like) Spectroscopy and Decay at BESIII

The recent results on Charmonium and Charmonium-like states at BESIII are reviewed, including the observation of ${\mathrm{Z}}_{\mathrm{c}\mathrm{s}}(3985)$ state, the study of the new decay modes of ${\psi }_2(3823)$ state, observation of resonance structure in ${\mathrm{e}}^{+}{\mathrm{e}}^{-}\to {\pi }^{+}{\pi }^{-}{\psi }_2(3823)$ process, the study of the ${\mathrm{e}}^{+}{\mathrm{e}}^{-}\to {\mathrm{K}}^{+}{\mathrm{K}}^{-}\mathrm{J}\mathrm{/}\psi$ process, cross section measurement of ${\mathrm{e}}^{+}{\mathrm{e}}^{-}\to \omega {\pi }^0$ and $\omega \eta$ process, branching fraction measurement of $\psi (3686)\to {\bar{\mathrm{\Sigma }}}^0\mathrm{\Lambda }+c\mathrm{.}c\mathrm{.}$ process. Decay channels for ${\chi }_{cJ}\to \mathrm{\Lambda }\bar{\mathrm{\Lambda }}$, ${\chi }_{cJ}\to \mathrm{\Lambda }\bar{\mathrm{\Lambda }}\eta$, $\psi (3686)\to \mathrm{\Lambda }\bar{\mathrm{\Lambda }}\omega$ and ${\eta }_c(2S)\to 3({\pi }^{+}{\pi }^{-})$ are also discussed. The property of the spin singlet P wave Charmonium state, ${\mathrm{h}}_{\mathrm{c}}$ is also reported.
