The $g_{{\Sigma }_Q{\Sigma }_Q\pi }$ Coupling Constant via Light Cone QCD Sum Rules

Abstract

Using the most general form of the interpolating currents, the coupling constants $g_{{\Sigma }_b{\Sigma }_b\pi }$ and $g_{{\Sigma }_c{\Sigma }_c\pi }$ are calculated within the light cone QCD sum rules approach. It is found that $g_{{\Sigma }_c{\Sigma }_c\pi }=-8.0\pm 1.7$ and $g_{{\Sigma }_b{\Sigma }_b\pi }=-11.0\pm 2.1$.
