Özet

We investigate the a(0) -> pi(0)eta decay in the framework of QCD sum rules. We estimate the coupling constant g(a0 pi eta) which plays an essential role in the analysis of physical processes involving a(0)(980) meson. We also estimate the coupling constant g(a0 pi eta) by using the experimental limits of the decay width of the a(0) -> pi(0)eta decay and compare with our QCD sum rule result.
