The gluon D-term at small x is a next-to-eikonal stress observable whose sign is not determined by the dipole or saturation profile.

D-term of nuclei exhibits kinks at magic neutron numbers, showing strong sensitivity of mechanical properties to shell structure.
Charmonium-nucleon femtoscopy is proposed as a probe of the nucleon D-form factor by constructing an effective potential from lattice gravitational form factors and matching it to HAL QCD results.
Hadronic form factors violate QCD dispersion relations due to incomplete time-like spectral data above the last known resonance, which radial Regge trajectories can fill as a minimal ansatz, shown for the pion form factor.
A hadronic approach based on dispersion relations and meson dominance achieves a successful description of lattice QCD data for gravitational form factors of pions and nucleons.
