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 $g_{{\Sigma_{c}\Sigma_{c}\pi}}=-8.0\pm1.7$ and $g_{{\Sigma_{b}\Sigma_{b}\pi}}=-11.0\pm2.1$.

    hep-ph 2025-11 unverdicted novelty 5.0

    Light-cone sum rules yield radiative decay widths for ground-state vector mesons that match data where available and exhibit a universal linear dependence on a function A(x) in log coordinates arising from decay-const...
