The strong $I^_{b} N B$ and $I^_{c} N D$ vertices

arXiv:1410.7548 · doi:10.1103/PhysRevD.90.114011

Abstract

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