Linear sigma model predictions for V→Sγ and S→Vγ decays

The radiative decays V→Sγ and S→Vγ with V=ρ,ω,ϕ and S=a0,σ,f0 are calculated within the framework of the Linear Sigma Model. Current experimental data on the ϕ→f0γ and ρ→σγ branching ratios and the ratio Γ(ϕ→f0γ)/Γ(ϕ→a0γ) are satisfactorily accommodated in our approach. We also estimate the decay widths of the f0,a0→ργ,ωγ transitions. All the processes considered are of interest for ongoing experimental programs in Frascati, Jülich and Novosibirsk.
