Within the framework of the Khuri–Treiman equations, we show that the ω→3π Dalitz-plot parameters obtained with a once-subtracted amplitude are in agreement with the latest experimental determination by BESIII. Furthermore, we show that at low energies the ωπ0 transition form factor obtained from our determination of the ω→3π amplitude is consistent with the data from MAMI and NA60 experiments.engAtribución 3.0 España$$\omega \rightarrow 3\pi $$ and $$\omega \pi ^{0}$$ transition form factor revisitedjournal articlehttps://doi.org/10.1140/epjc%2Fs10052-020-08576-6https://link.springer.com/article/10.1140/epjc/s10052-020-08576-6open accessFísica-Modelos matemáticosFísica matemática
