a0→ π 0η Decay in QCD Sum Rules
Abstract
We investigate the a0→ π 0η decay in the framework of QCD sum rules. We estimate the coupling constant ga0π η which plays an essential role in the analysis of physical processes involving a0(980) meson. We also estimate the coupling constant ga0π η by using the experimental limits of the decay width of the a0→ π 0η decay and compare with our QCD sum rule result.
