$\ddot{I}•\to 3\ddot{I}€$ and $\ddot{I}•\ddot{I}{€}^0$ transition form factor from Khuri-Treiman equations

A. Garcia-Lorenzo, M. Albaladejo, S. Gonzlez-Solis +6

This work studies the $\ddot{I}•\to 3\ddot{I}€$ decay and the $ϕ\to π^0 γ^\ast$ transition form factor, utilizing the Khuri-Treiman formalism to account for analyticity, crossing, and unitari…
