Abstract：
We have examined the parametrization of the e ⁺e ^-→ ωπ ⁰cross section in the vicinity of the φ resonance and the extraction of the branching fraction of the isospin violating process φ → ωπ ⁰from experimental data. We found that there are two possible solutions of the branching fraction: one is 4 × 10 ^-5, and the other is 7 × 10 ^-3. The latter is two orders of magnitude higher than the former, which is the commonly accepted one.
