# Gravitational form factors of a spin one particle

## TL;DR

This paper defines gravitational form factors for a spin-one particle, linking energy-momentum tensor form factors to spatial distributions of energy, spin, pressure, and shear forces, and relates them to generalized parton distributions.

## Contribution

It introduces a formalism for gravitational form factors of a spin-one particle and connects them to spatial distributions and generalized parton distributions.

## Key findings

- Form factors related to energy, spin, pressure, and shear forces are derived.
- Multipole expansion of the static energy-momentum tensor is provided.
- Relations between gravitational form factors and generalized parton distributions are established.

## Abstract

We define the form factors of the quark and gluon symmetric energy-momentum tensor (EMT). The static EMT is related to the spatial distributions of energy, spin, pressure and shear forces. They are obtained in the form of a multipole expansion. The relations between gravitational form factors and the generalised parton distributions are given.
