Nucleon Gravitational Form Factors
read the original abstract
A symmetry-preserving analysis of strong interaction quantum field equations is used to complete a unified treatment of pion, kaon, nucleon electromagnetic and gravitational form factors. Findings include a demonstration that the pion near-core pressure is roughly twice that in the proton, so both are significantly greater than that of a neutron star; parton species separations of the nucleon's three gravitational form factors, in which, inter alia, the glue-to-quark ratio for each form factor is seen to take the same constant value, independent of momentum transfer; and a determination of proton radii orderings, with the mechanical (normal force) radius being less than the mass-energy radius, which is less than the proton charge radius. This body of predictions should prove useful in an era of anticipated experiments that will enable them to be tested.

Experimental access to the gluonic origin of the proton mass
The scalar gluonic trace form factor of the proton can be reconstructed from DVCS quark GFFs, near-threshold J/ψ gluon GFFs, and the nucleon sigma-term form factor.

Gravitational transverse momentum distribution of proton
Analytical expressions for quark gravitational TMDs are derived in the LFQDM, verified against standard TMD relations, and linked to transverse pressure and shear-force distributions.

Gluon Gravitational $ D$-Form Factor: The $\sigma$-Meson as a Dilaton Confronted with Lattice Data II
Lattice fits to gluon gravitational form factors support the sigma meson as dilaton with new predictions for rho and delta, reinforcing evidence for scale symmetry in low-energy QCD.

The color force acting on a quark in the pion and nucleon
In the instanton liquid model, the color force on a struck quark in the pion and nucleon is derived from twist-3 operators, related to gravitational and transversity form factors, and mapped in the transverse plane wi...
