Abstract

In this report I review some results on the charmonium and light hadron spectroscopy mainly from BESIII and Belle experiments. For the charmonium, the contents include the observation of ψ(4040)/ψ(4160)η\jpsi\psi(4040)/\psi(4160) \to \eta \jpsi, the measurements of the ηc/ηc(2S)\eta_c/\eta_c(2S) resonance parameters and their decays, the evidence of the ψ2(13D2)\psi_2(1^3D_2) state in the χc1γ\chi_{c1}\gamma mass spectrum. For the light hadron spectroscopy, the contents include the X(1835)X(1835) research in e+e\jpsi+X(1835)e^+e^- \to \jpsi + X(1835) and γγηπ+π\gamma \gamma \to \eta' \pi^+ \pi^- processes, and the analysis of the ηη\eta \eta, ωϕ\omega \phi, ϕϕ\phi\phi and ωω\omega \omega mass spectra in low mass region.
