Radiative J/psi decays and the pseudoscalar puzzle
Conference

OSTI ID:5370897
Recent results on radiative decays of the J/PSI, obtained by the SPEAR detectors Mark III and Crystal Ball and the DCI detector DM2 at Orsay, are presented. The status of the glueball candidates theta(1690), iota(1460), and xi(220), and the decays J/PHI ..-->.. ..gamma.. Vector Vector are reviewed. A coupled channel analysis of iota(1460) decays to K anti K..pi.., rho rho, ..omega omega.., and ..gamma..rho is presented which may help to understand the pseudoscalar sector in radiative J/PHI decays. 42 refs., 16 figs.
