We present a high-quality description of the deuteron electromagnetic form factors in a soft-wall AdS/QCD approach. We first propose an effective action describing the dynamics of the deuteron in the presence of an external vector field. Based on this action the deuteron electromagnetic form factors are calculated, displaying the correct 1/Q^10 power scaling for large Q^2 values. This finding is consistent with quark counting rules and the earlier observation that this result holds in confining gauge/gravity duals. The Q^2 dependence of the deuteron form factors is defined by a single and universal scale parameter kappa, which is fixed from data.

Structure of lightest nuclei in the visible Universe
A two-cluster light-front model with three fitted parameters reproduces several deuteron observables, while the hidden-color mixture used to explain them is not explicitly computed.

Generalized parton distributions of a deuteron in an AdS/QCD hard-wall model
Deuteron GFFs and GPDs calculated in hard-wall AdS/QCD agree in momentum dependence with soft-wall results and match experimental gravitational mean square radius.
