Strong Sigma N-b B and Sigma N-c D coupling constants in QCD

2015    Azizi, K.; Sarac, Y.; Sundu, H.

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. (C) 2015 Elsevier B.V. All rights reserved.
