Recent BES Results on psi' Decay
X. H. Mo
Abstract
With 14 Million psi' events, many two-body decay channels are studied, which include Vector Pseudoscalar, Vector Tensor, Pseudoscalar Pseudoscalar channels. Based on systematical measurements for charmonium decay, 12% rule is tested, the phase between strong and electromagnetic amplitudes is studied. In addition, hadronic and radiative transitions of charmonia are measured to improve experimental accuracy and test theoretical calculations.
