| dc.description | The coupled channel model of the a0(980) and a0(1450) resonances has been constructed using the separable pion-eta and K-anti K interactions. We have shown that two S-matrix poles corresponding to the a0(980) meson have significantly different widths in the complex energy plane. The K-anti K to pion-eta branching ratio, predicted in our model near the a0(1450) mass, is in agreement with the result of the Crystal Barrel Collaboration. The K-anti K interaction in the S-wave isovector state is not sufficiently attractive to create a bound a0(980) meson. | |
