Deuteron Electromagnetic Form Factors in AdS/QCD

Abstract

We extend a soft-wall AdS/QCD approach to a description of deuteron properties. Our framework is based an effective action formulated in terms of AdS fields, which are holographically equivalent to the deuteron and photon fields. This action produces the equation of motion for the deuteron wave function and the \(Q^2\)-dependent electromagnetic current, which are then used to calculate the deuteron electromagnetic form factors and structure functions in the Euclidean region. We show that the predicted deuteron quantities are expressed through a universal function, which is defined by a single scale parameter \(\kappa \) and which has the correct \(1/Q^{10}\) power scaling at large \(Q^2\).
