Abstract: | It is shown that Fπ(s) can be calculated in a model independent way if one knows the phase δ1 and the inelasticity η of the p-wave ππ scattering and also Fπ and the form factor of the γ1 → π°ω transition for s> (mω + mπ)2. The correction on Fπ(s) for s< (mω + mπ)2 due to the πω state with a strong ?′(1250) allows to explain the discrepancy between ?-dominance predictions and the experimental data. |
