$\pi^0$-$\eta$-$\eta^{\prime}$ mixing from $V\!\rightarrow\!P\gamma$ and $P\!\rightarrow\!V\gamma$ decays

An enhanced phenomenological model that includes isospin-symmetry breaking is presented in this letter. The model is then used in a number of statistical fits to the most recent experimental data for the radiative transitions $V ⁣ P γ$ ( $V = ρ$ , $K^{*}$ , $ω$ , $ϕ$ and $P = π$ , $K$ , $η$ , $η^{'}$ ) and estimations for the mixing angles amongst the three pseudoscalar states with vanishing third-component of isospin are obtained. The quality of the performed fits is good, e.g. $χ_{min}^{2} / d.o.f = 1.9$ . The current experimental uncertainties allow for isospin symmetry violations with a confidence level of approximately $2.5 σ$ .
