Hadron Spectroscopy from BES and CLEOc
Yuan, Chang-Zheng
Original · EN
Recent results from BES and CLEOc experiments on hadron spectroscopy and charmonium decays using J/psi, psi' and psi'' data samples collected in e+e- annihilation are reviewed, including the observation of X(1835) in J/psi --> gamma pi+ pi- eta', study of the scalar particles in J/psi radiative and hadronic decays, as well as in chic0 hadronic decays, and the study of the ``ρπpuzzle'' in J/psi, psi', and psi'' decays. We also make a few comments on partial wave analysis, and the study of the ρπpuzzle.
