Radiative decays of the {upsilon}(1S) to {gamma}{pi}{sup 0}{pi}{sup 0}, {gamma}{eta}{eta} and {gamma}{pi}{sup 0}{eta}

We report on a study of exclusive radiative decays of the Υ(1S) resonance into the final states γπ0π0, γηη and γπ0η, using 1.13 fb−1 of e+e− annihilation data collected at √ s = 9.46GeV with the CLEO III detector operating at the Cornell Electron Storage Ring. In the channel γπ0π0, we measure the branching ratio for the decay mode Υ(1S) → γf2(1270) to be (10.5 ± 1.6 (stat) +1.9 −1.8 (syst)) × 10−5. We place upper limits on the product branching ratios for the isoscalar resonances f0(1500) and f0(1710) for the π 0π0 and ηη decay channels. We also set an upper limit on the Υ(1S) radiative decay into π0η. PACS numbers: 13.20.Gd, 12.39.Mk

Using 5.63 pb{sup -1} of data accumulated at the {psi}(2S) resonance with the CLEO III and CLEO-c detectors corresponding to 3.08x10{sup 6} {psi}(2S) decays, a search is performed for the decay {psi}(2S){yields}{eta}{sub c}{pi}{sup +}{pi}{sup -}{pi}{sup 0} to test a theoretical prediction based upon the assumption that the cc pair in the {psi}(2S) does not annihilate directly into three gluons but rather survives before annihilating. No signal is observed, and a combined upper limit from six {eta}{sub c} decay modes is determined to be B({psi}(2S){yields}{eta}{sub c}{pi}{sup +}{pi}{sup -}{pi}{sup 0}){<=}1.0x10{sup -3} at 90% C.L. This upper limit is about an order of magnitude below the theoretical expectation.Using
