\[49\]. The model has a mass scale $M_{KK}$ like the SS model in which we set its value by computing the pion decay constant. Then, we study the baryon \[50\] and obtain its size. We show that the size of the baryon is of order one with respect to the ’t Hooft coupling, so the problem of the zero size of the baryon in the critical holography model is solved. But the size of the baryon is still smaller than the mass scale of holographic QCD, so we treat it as a point-like object and introduce an isospin $1/2$ Dirac field for the baryon \[49\]. We write a 5D effective action for the baryon field and reduce it to 4D using the mode expansion of gauge field and baryon field and obtain the NN potential in terms of the meson exchange interactions. We calculate the meson-nucleon couplings using the suitable overlapping wave function integrals and compare them with the results of SS model. Also, we compare the nucleon-meson couplings obtained from noncritical holographic model with the results of SS model and predictions of some phenomenological models. Our study shows that the noncritical results are in good agreement with the other
