Strong $\Sigma_bNB$ and $\Sigma_cND$ coupling constants in QCD

High Energy Physics - Phenomenology 2015-09-29 v3 Nuclear Theory

Abstract

We study the strong interactions among the heavy bottom spin--1/2 Σb\Sigma_b baryon, nucleon and BB meson as well as the heavy charmed spin--1/2 Σc\Sigma_c baryon, nucleon and DD meson in the context of QCD sum rules. We calculate the corresponding strong coupling form factors defining these vertices by using a three point correlation function. We obtain the numerical values of the corresponding strong coupling constants via the most prominent structure entering the calculations.
