Abstract

We study the deuteron charge radius in the framework of a hard-wall AdS/QCD model. We present basic elements of the hard-wall model and write metrics for the AdS space. We introduce a vector field with twist τ=6 describing deuteron in the bulk of AdS space and other vector fields to describe photon respectively, write an effective action for the bulk fields interactions, find a G₁(Q²), G₂(Q²) and G₃(Q²) form factors, then quadrupole G_Q(Q²) and charge G_C(Q²) form-factors of a deuteron. Thus, from the charge G_C(Q²) form factor we find the deuteron charge radius R_C in the framework of a hard-wall AdS/QCD model. Then we compare our result with the results soft-wall model and experimental data.
