The strong $\Lambda_bNB$ and $\Lambda_cND$ vertices
  We investigate the strong vertices among $\Lambda_b$, nucleon and $B$ meson as well as $\Lambda_c$, nucleon and $D$ meson in QCD. In particular, we calculate the strong coupling constants $g_{\Lambda_bNB}$ and $g_{\Lambda_cND}$ for different Dirac structures entered the calculations. In the case of $\Lambda_cND$ vertex, the result is compared with the only existing prediction obtained at $Q^2=0$.
