Abstract: (Elsevier)

It is shown how broken SU3 with U -spin invariance of the electromagnetic interactions, tadpole dominance for the ‖ ΔI ‖ = 1 mass differences, and generalized Weinberg sum rules all agree in predicting a ϱω mixing effect which is consistent with the experimental results Γ ω →2 π ≈ 0.4 MeV.
