Description
The world’s larges sample of 4.48108 psi(2S) events provides good opportunities for the study of chi_cJ, eta_c, and h_c decays via its radiative transition. Using this data sample, a lot of progress on chi_cJ and h_c decays has been made. New results, including the observation of OZI suppressed decays chi_cJ -> phi omega, measurements of chi_cJ-> phi phi eta, observation of chi_cJ -> 4 Ks and sigma p-bar Ks, observation of new h_c hadronic decay modes will be introduced.
