Radiative Decays of Basic Scalar, Vector and Tensor Mesons and the Determination of the P-Wave Qbar {Q} Multiplet

We perform simultaneous calculations of the radiative decays of scalar mesons f₀(980) → γγ, a₀(980) → γγ, vector meson φ(1020) → γf₀(980), γa₀(980), γπ⁰, γη, γη' and tensor mesons a₂(1320) → γγ, f₂(1270) → γγ, f₂(1525) → γγ assuming all these states to be dominantly the qbar {q} ones¹. A good description of the considered radiative decays is reached by using almost the same radial wave functions for scalar and tensor mesons that supports the idea for the f₀(980), a₀(980) and a₂(1320), f₂(1270), f₂(1525) to belong to the same P-wave qbar {q} multiplet.
