Abstract

In the framework of the local Nambu-Jona-Lasinio model the radiative decay widths of the scalar mesons f₀(980) and a₀(980) into ργ and ωγ are calculated. The contributions of the quark loops and the meson loops are taken into account. For the radiative decays of the scalar meson f₀(980) the contribution of the meson loops plays the dominant role. On the other side for the radiative decays of the scalar meson a₀(980) the main contribution is given by the quark loops.
