摘要：
In the framework of the soft-wall model of AdS/QCD we calculated the ρ meson nucleon coupling constant. Bulk-to boundary propagators for the free vector and spinor fields are presented, whose boundary values correspond to ρ 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 gρNN coupling constant in the boundary QCD. We found that the soft-wall model result for the gρNN constant is more close to empirical values than the one obtained in the hard-wall model.
