Abstract
We study the strong interactions among the heavy bottom spin--1/2 baryon, nucleon and meson as well as the heavy charmed spin--1/2 baryon, nucleon and 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.
