Experimental Status of Conventional Charmonium Spectroscopy

Based on data samples taken by the BESIII, Belle, KEDR and LHCb experiments, many measurements on conventional charmonium spectroscopy were finished in the past years. Some of recent results, such as precise measurements of J/ψ and ψ(2S) masses, the J/ψ decay width, the J/ψ and ψ(2S) electronic widths, two-photon width of χ_c0,2 meson, the χ_c1,2 resonance parameters with the decays χ_c0,2 → J/ψµ⁺µ⁻, the η_c resonance parameters and observations of X(3823) and X^*(3860), were reported.
