Radiative decays of basic scalar, vector and tensor mesons and the determination of the P-wave q multiplet

Abstract.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 q ones. 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 q multiplet.
