abstract

We study the strong interactions among the heavy bottom spin--1/2 $\Sigma_b$ baryon, nucleon and $B$ meson as well as the heavy charmed spin--1/2 $\Sigma_c$ baryon, nucleon and $D$ 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.

    A QCD sum rule analysis produces masses, pole residues and six on-shell strong coupling constants for the ΛcD(*)N*(1535) and ΛbB(*)N*(1535) vertices.
