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.

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.
