abstract

We examine the spatial density within extended objects of the momentum component $p^+$, and find relativistically exact connections to Fourier transforms of gravitational form factors. We apply these results to obtain semi-empirical momentum density distributions within nucleons, and similar distributions for spin-1 objects based on theoretical results from the AdS/QCD correspondence. We find that the momentum density in the transverse plane is more compact than the charge density.

  1. Transverse energy-momentum tensor distributions in polarized nucleons

    hep-ph 2026-04 unverdicted novelty 6.0 of 10

    Transverse EMT distributions in polarized nucleons are derived in the quantum phase-space formalism; they reduce to standard light-front densities (including bad components) in the infinite-momentum frame.

  2. Relativistic energy-momentum tensor distributions in a polarized nucleon

    hep-ph 2025-03 unverdicted novelty 6.0 of 10

    Relativistic EMT distributions in polarized nucleons recover good and bad light-front components in the IMF after including polarization effects.

  3. Mechanical properties of the proton from a deformed AdS holographic model

    hep-ph 2025-11 conditional novelty 4.0 of 10

    A deformed AdS holographic model with a Dirac proton computes the gluon gravitational form factor A in good agreement with lattice QCD after normalizing the zero point, but the D-term and derived pressure/shear distri...

  4. Deuteron gravitational form factors, generalized parton distributions, and charge density in the framework of the soft-wall AdS/QCD model

    hep-ph 2024-12 conditional novelty 4.0 of 10

    The deuteron is modeled as a twist-6 vector field in thermal soft-wall AdS/QCD, yielding gravitational form factors, GPDs, and charge densities whose temperature dependence is governed by a modified dilaton parameter.

  5. Generalized parton distributions of a deuteron in an AdS/QCD hard-wall model

    hep-ph 2026-06 unverdicted novelty 3.0 of 10

    Deuteron GFFs and GPDs calculated in hard-wall AdS/QCD agree in momentum dependence with soft-wall results and match experimental gravitational mean square radius.
