Abstract
We use meson pairs collected at the resonance with the Belle detector to measure the branching fraction for . Our measurement uses a sum-of-exclusives approach in which 38 of the hadronic final states with strangeness equal to , denoted by , are reconstructed. The inclusive branching fraction for , which corresponds to a minimum photon energy of 1.9 GeV, is measured to be , where the first uncertainty is statistical and the second is systematic.
