Hadronic decays of charmonia from BESII
Chang-Zheng Yuan
Abstract
Recent results on charmonia decays at BESII/BEPC are reported, including the observation of psi'-->KS KL, psi'--> Vector + Tensor and psi'--> Vector + Pseudoscalar 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 test of the color-octet mechanism via chicJ --> p p and chicJ-->ΛΛ; the first observation of chic0--> f0(980)f0(980); and a study of the psi' and chicJ decays with KS KS in the final states.
