Khuri-Treiman analysis of J=ψ → π + π − π0
We study the decay J/ψ→π+π-π0 within the framework of the Khuri-Treiman equations. We find that the BESIII experimental dipion mass distribution in the ρ(770)-region is well reproduced with a once-subtracted P-wave amplitude. Furthermore, we show that F-wave contributions to the amplitude improve th...

| Sumario: | We study the decay J/ψ→π+π-π0 within the framework of the Khuri-Treiman equations. We find that the BESIII experimental dipion mass distribution in the ρ(770)-region is well reproduced with a once-subtracted P-wave amplitude. Furthermore, we show that F-wave contributions to the amplitude improve the description of the data in the ππ mass region around 1.5 GeV. We also present predictions for the J/ψ→π0γ* transition form factor. |
