| Abstract: | Based on the four-quark interpretation of the scalara 0(980) meson a model for theγγ→a 0→π 0 η reaction amplitude is constructed which describes well the experimental data. The ideas about the nature of thea 0(980) meson which appeared after the Crystal Ball measurement of the two-photon production of thea 0 meson are discussed briefly. |
