Measurement of the Branching Fraction of J/psi --> pi+ pi- pi0
Abstract
Using 58 million J/psi and 14 million psi' decays obtained by the BESII experiment, the branching fraction of J/psi --> pi+ pi- pi0 is determined. The result is (2.10+/-0.12)X10-2, which is significantly higher than previous measurements.
