The vector meson delta-baryon coupling constant in the framework of a soft-wall model AdS/QCD

In this paper, we study the interaction of a vector meson with delta baryons in the framework of a soft wall model AdS/QCD. Inside the Anti-de Sitter (AdS) space has been introduced a pseudoscalar field for breaking chiral symmetry, gauge fields with left and right chiral symmetries, and Rarita-Schwinger fields. The vector field is determined using gauge fields with left and right chiral symmetries, and profile functions for all these fields are introduced into the AdS space. Additionally, a minimal gauge and magnetic gauge Lagrangian interactions were introduced interior the AdS space. Using the interaction Lagrangian and according to the AdS/CFT (conformal field theory), the coupling constant of the vector meson with delta baryons is obtained as an integral over an additional dimension. Using the computer program “Mathematics 7”, the numerical values of the coupling constant of the vector meson with the delta baryon in the soft wall model AdS/QCD were determined.
