Abstract

Using 53 pb-1 of e+e- annihilation data taken at the ψ(2S) resonance, a comprehensive study has been made of the radiative decays of samples of 5.1 million J/ψ and 24.5 million ψ(25) into pairs of pseudoscalar mesons, π+π-, π0π0, K+ K-, KS0KS0 and ηη. Product branching fractions for the radiative decays of J/ψ and ψ(2S) to scalar and tensor resonances have been determined, and are discussed in relation to predicted glueballs. For ψ(25) radiative decays, the search for glueballs has been extended to masses between 2.5 GeV and 3.3 GeV.
