| dc.description | Recent results on charmonia decays at BES/BEPC are reported, including the observation of psi'-->K_S K_L, psi'--> Vector + Tensor for the measurement of the relative phase between the strong and electromagnetic decays of psi' and a test of the pQCD ``12% rule'' between psi' and J/psi decays; the study of psi'--> gamma gamma J/psi for the determination of psi'--> pi^0 J/psi, eta J/psi, gamma chi_c1 and gamma chi_c2 decay branching fractions; the test of the color-octet mechanism via chi_cJ--> p \bar{p} and chi_cJ--> Λ\barΛ; and a search for the CP violating process psi' and J/psi--> K_S K_S. | |
