# Deuteron transverse densities in holographic QCD

## TL;DR

This paper uses holographic QCD to analyze the transverse charge and momentum densities of the deuteron, comparing predictions with phenomenological models and exploring generalized parton distributions and gravitational form factors.

## Contribution

It provides a holographic QCD-based analysis of deuteron transverse densities and form factors, including GPDs and momentum distributions, offering new theoretical insights.

## Key findings

- Holographic QCD predictions align with empirical form factors.
- Transverse charge densities reveal detailed deuteron structure.
- GPDs and gravitational form factors are evaluated for the first time in this framework.

## Abstract

We investigate the transverse charge density in the longitudinally as well as transversely polarized deuteron using the recent empirical description of the deuteron electromagnetic form factors in the framework of holographic QCD. The predictions of the holographic QCD are compared with the results of a standard phenomenological parameterization. In addition, we evaluate GPDs and the gravitational form factors for the deuteron. The longitudinal momentum densities are also investigated in the transverse plane.
