Quadrupole pressure and shear forces inside baryons in the large N limit

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

“…[20,44] and newly parametrized in Refs. [14,43] to conveniently express the strong forces in a hadron acting on the radial area element. Following Refs.…”

“…Following Refs. [14,43] we can express the stress tensor in terms of the pressure and shear forces densities by…”

“…The functions p 2 (r ) and p 3 (r ) are named the quadrupole pressure densities, and the s 2 (r ) and s 3 (r ) are called the quadrupole shear force densities according to Ref. [14]. These densities p n (r ) and s n (r ) are respectively written as…”

“…[13], the relevant structure for the GFFs of the was sorted out. The general properties of the pressure and shear forces for the isobar were derived in the large-N c limit [14]. Compared to the GFFs of the nucleon, the GFFs of the isobar have a far more complicated structure: ten different kinds of the GFFs together with the EMT-nonconserving form factors.…”

“…For the higher spin hadrons, the works on the parametrization of the stress tensor are made in Refs. [14,44].…”
