The a0K+K--vertex in light cone QCD sum rules
Abstract
We investigate the a0K+K--vertex in the framework of light cone QCD sum rules. We estimate the coupling constant ga0K+K- which is an essential ingredient in the analysis of physical processes involving a0(980) meson. Our result is somewhat larger than the previous determinations of this coupling constant.
