New results on radiative J/psi decays from MARK III at SPEAR

Conference ·
OSTI ID:6875968
Selected topics on radiative decays of the J/psi from MARK III at SPEAR are presented. These topics include the decay J/psi ..-->.. ..gamma..K anti K where the final state resonances f'(1515), theta(1700) and xi(2200) have been analyzed. The decay J/psi ..-->.. (..gamma.. vector vector) is presented in three final states, J/psi ..-->.. ..gamma.. phi phi, ..gamma.. rho rho and ..gamma omega omega.., providing the first measurement of the eta/sub c/ spin-parity (in ..gamma.. phi phi) and evidence for structures (in ..gamma.. rho rho and ..gamma omega omega..) near 1.7 GeV. 24 references.
