- Abstract
In light of recent experimental results, we revisit the dispersive analysis of the ω → 3 π decay amplitude and of the ω π 0 transition form factor. Within the framework of the Khuri–Treiman equations, we show that the ω → 3 π 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 ω π 0 transition form factor obtained from our determination of the ω → 3 π amplitude is consistent with the data from MAMI and NA60 experiments.
