We work out details of defining the spatial densities corresponding to the gravitational form factors of spin-0 and spin-1/2 systems using spherically symmetric sharply localized wave packets. The expressions for the spatial densities are provided in the frames with both zero and non-zero expectation values of the momentum operator.

  1. Quantum stress and torsion distributions in the deuteron

    nucl-th 2026-02 conditional novelty 7.0 of 10

    First complete non-relativistic impulse-approximation calculation of all eleven deuteron EMT form factors, including non-conserved c-bar and s-bar form factors that map to force and torsion distributions inside the nucleons.

  2. Reconstruction of Gravitational Form Factors using Generative Machine Learning

    hep-ph 2026-02 conditional novelty 6.0 of 10

    A diffusion model trained on synthetic physics-motivated curves reconstructs the proton's A(t), J(t), D(t) from sparse data, extracting c8=-4.6±0.8, c9=-0.61±0.19, and D(0)=-4.3±0.8.

  3. Gravitational form factors of the Higgs boson

    hep-ph 2025-08 conditional novelty 6.0 of 10

    The one-loop electroweak gravitational form factors of the Higgs give a finite theta2 and an energy radius r^2 approximately 1.44e-6 GeV^-2, with theta1 requiring an EFT counterterm.

  4. Mechanical properties of the $\Omega^-$ baryon from gravitational form factors

    hep-ph 2025-07 conditional novelty 5.0 of 10

    Using QCD sum rules, the authors extract seven gravitational form factors of the Omega baryon and derive its internal energy, angular momentum, pressure, shear, radii, and D-terms.
