Radiative decays of the Upsilon(1S) to gamma pi(0)pi(0), gamma eta eta and gamma pi(0)eta Academic Article uri icon

abstract

  • We report on a study of exclusive radiative decays of the (1S) resonance into the final states 00, and 0, using 1.13fb-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 00, we measure the branching ratio for the decay mode (1S)f2(1270) to be (10.51.6(stat)-1.8+1. 9(syst))10-5. We place upper limits on the product branching ratios for the isoscalar resonances f0(1500) and f0(1710) for the 00 and decay channels. We also set an upper limit on the (1S) radiative decay into 0. 2007 The American Physical Society.
