Results from Charmonium Decays
Chang-Zheng Yuan
Abstract
Recent results from BES and CLEOc experiments on charmonium decays using J/psi, psi' and psi'' data samples collected in e+e- annihilation are reviewed, including the measurement of the relative phase between strong and electromagnetic decays of psi', the study of the ``rho pi puzzle'' in J/psi and psi' decays, and the search for the non-DDbar decays of psi''. The decays of chicJ produced in psi' radiative transition are also reviewed. These new results shed light on the understanding of QCD.
