Analysis of the coupling constants ga0ηπ0 and ga0η′π0 with light-cone QCD sum rules
a0(980) light-cone QCD sum rules
2009/12/24
In this article, we take the point of view that the light scalar meson a0(980) is a conventional qq state, and calculate the coupling constants ga0ηπ0 and ga0η′π0 with the light-cone QCD sum rules. Th...
