Gravitational form factors of a baryon with spin-3/2

The energy-momentum tensor (EMT) for a spin-3/2 baryon is related to \emph{seven} mechanical quantities. In this work, we provide the general form of the gravitational form factors (GFFs) for a spin-3/2 baryon by using the multipole expansion and interesting relations between the EMT densities and the GFFs. To verify those general relations, we study the nucleon and the $Δ$ GFFs within the SU(2) Skyrme model based on the large $N_{c}$ limit.
