$\omega \to 3\pi$ and $\omega\pi^{0}$ transition form factor revisited
In light of recent experimental results, we revisit the dispersive analysis of the $\omega \rightarrow 3\pi $ decay amplitude and of the $\omega \pi ^0$ transition form factor. Within the framework of the Khuri–Treiman equations, we show that the $\omega \rightarrow 3\pi $ Dalitz-plot parameters obt...

description | In light of recent experimental results, we revisit the dispersive analysis of the $\omega \rightarrow 3\pi $ decay amplitude and of the $\omega \pi ^0$ transition form factor. Within the framework of the Khuri–Treiman equations, we show that the $\omega \rightarrow 3\pi $ 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 $\omega \pi ^0$ transition form factor obtained from our determination of the $\omega \rightarrow 3\pi $ amplitude is consistent with the data from MAMI and NA60 experiments. |
