Abstract

We study the processes , , and using a data sample of recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy collider at center-of-mass energies at and near the (, 3, 4) resonances. This is the first observation of the decay and we measure the branching fraction . Significant interference is observed between and the nonresonant two-photon process . A Dalitz plot analysis is performed of decays to , , and . Combined with our previous analysis of , we measure the parameters and the ratio between its and couplings. The decay is dominated by the resonance, also observed in radiative decays. A new resonance is observed in the channel. We also compare decays to and final states in association with scalar mesons as they relate to the identification of the scalar glueball.
