Abstract

The decay Ï(2S)â†Î•J/Ï is used to measure, for the first time, all prominent Î•-meson branching fractions with the same experiment in the same dataset, thereby providing a consistent treatment of systematics across branching fractions. We present results for Î• decays to ÎÎ, Ï€+Ï€- Ï€0, 3Ï€0, Ï€+Ï€-Î and e+e-Î, accounting for 99.9% of all Î• decays. The precision of several of the branching fractions and their ratios is improved. Two channels, Ï€+Ï€-Î and e+e-Î show results that differ at the level of three standard deviations from those previously determined.
