Description

With the worldly largest psi(2S) samples collected at BEESIII, systematic studies of the decays of eta_c(2S) are performed. As an example, the observation of the decay eta_c(2S) -> 3 (pi+ pi-) will be reported in this talk. Based on the 450M psi(2S) samples, the mass and width of h_c are updated as well as the branching fraction of psi(2S) -> pi0 h_c. In this talk, search for new hadronic decays of h_c and observation of h_c -> proton anti-proton eta will be reported too. And the upper limit of h_c -> pi0 J/psi will be provided. This analysis utilizes the electron-positron collision data at the energy regions above 4 GeV.
