Description
Consequences following from the SU(3) symmetry, from the quark model and from dispersion sum rules are treated for two-photon decays of tensor mesons. In the SU(3) model with the mixing angle given by the mass formula, the prediction for GITA(f'→2γ) agrees with the experiment at reasonable values of B(f'→K anti K). The following results are obtained making use of the sum rules: GITA(f'→2γ)=2.62+-0.44 keV, GITA(A2 → 2γ)--0.89+-0.33 keV, and GITA(f'→2γ)B(f' → K anti K)=0.061+-0.005 keV if GITA(K*0 → K0 γ)=78 keV, 0.32+-0.13 keV if GITA(K*0 → K0γ)=248 keV
