摘要：

In the framework of the soft-wall model of AdS/QCD we calculated the rho meson nucleon coupling constant. Bulk-to boundary propagators for the free vector and spinor fields are presented, whose boundary values correspond to rho meson and to the nucleon respectively. The interaction Lagrangian between these fields is written in the bulk of AdS space and includes magnetic type interactions as well. Using the AdS/CFT correspondence from the bulk interaction action we derived the g (rho N N) coupling constant in the boundary QCD. We found that the soft-wall model result for the g (rho N N) constant is more close to empirical values than the one obtained in the hard-wall model.
