Description

psi(2S) provides good opportunities for the study of chi_cJ, eta_c, and h_c decays. These studies can be used to verify QCD based models, which provide predictions for the decay mechanism. With the world's largest sample of 4.48*10^8, progress on the charmonium decays has been made. In the talk, we report the new results, such as the first measurement of the branching ratioof chi_c1,2 to mu+ mu-; observation of chi_c1 to omega phi; observation of the h_c hadronic decays; the study of eta_c hadronic decay.
