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 Zcs(3985) state, the study of the new decay modes of ψ_2(3823) ψ2(3823) state, observation of resonance structure in e^+e^- → π^+π^-ψ_2(3823) process, the study of the e^+e^- → K^+K^-J/ψ process, cross section measurement of e^+e^- → ωπ^0 and ωη ωη process, branching fraction measurement of ψ(3686)→Σ̄^0Λ + c.c. ψ(3686)→Σ‾0Λ+c.c. process. Decay channels for χcJ → ΛΛ̄ χcJ→ΛΛ‾ , χcJ → ΛΛ̄η χcJ→ΛΛ‾η , ψ(3686) → ΛΛ̄ω ψ(3686)→ΛΛ‾ω and η_c(2S)→3(π^+π^-) ηc(2S)→3(π+π−) are also discussed. The property of the spin singlet P wave Charmonium state, h_c is also reported.
