Abstract

Using the most general form of the interpolating currents, the coupling constants gΣbΣbπg_{\Sigma_b\Sigma_b\pi} and gΣcΣcπg_{\Sigma_c\Sigma_c\pi} are calculated within the light cone QCD sum rules approach. It is found that gΣcΣcπ=8.0±1.7g_{{\Sigma_{c}\Sigma_{c}\pi}}=-8.0\pm1.7 and gΣbΣbπ=11.0±2.1g_{{\Sigma_{b}\Sigma_{b}\pi}}=-11.0\pm2.1.
