An extensive theoretical analysis of off-forward parton distributions (OFPDs) is presented. The OFPDs and the form factors of the quark energy-momentum tensor are estimated at a low-energy scale using a bag model. Relations among the second moments of OFPDs, the form factors, and the fraction of the nucleon spin carried by quarks are discussed.

Discussion (0). Continue with ORCID to comment.

  1. Generalized parton distributions of the kaon and pion within the nonlocal chiral quark model

    hep-ph 2024-11 conditional novelty 6.0 of 10

    The paper extends the nonlocal chiral quark model to strange quarks and computes kaon and pion generalized parton distributions, their QCD evolution, and strange-to-light gravitational form factor ratios.

  2. Origin of the nucleon gravitational form factor $B_N(t)$: Exposition in light-front holographic QCD

    hep-ph 2026-01 unverdicted novelty 5.0 of 10

    In light-front holographic QCD the nucleon gravitational form factor B_N(t) vanishes exactly in the symmetric limit due to an antisymmetric longitudinal factor and remains strongly suppressed for realistic nucleon wav...

  3. Mechanical properties of the nucleon from the generalized parton distributions

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Using a double-distribution GPD model constrained by elastic-scattering data, the paper fits DQ(0) = -3.37 ± 0.17 from Compton form factors and derives proton pressure, shear, and radii.

  4. Gluon skewed generalized parton distributions of proton from a light-front Hamiltonian approach

    hep-ph 2025-01 conditional novelty 5.0 of 10

    Using light-front wave functions with one dynamical gluon, the authors obtain all leading-twist gluon GPDs of the proton at nonzero skewness and find diffraction-like patterns in longitudinal position space.

  5. T-odd Wigner Distributions in boost-invariant longitudinal position space and Spin-momentum correlation in proton

    hep-ph 2024-08 unverdicted novelty 5.0 of 10

    T-odd leading-twist GTMDs in σ-space exhibit -t-dependent oscillations with transverse-longitudinal interference, while Sivers and Boer-Mulders Wigner distributions encode proton spin-transverse momentum correlations.

  6. Energy-momentum tensor densities in the bag model

    hep-ph 2019-07 unverdicted novelty 3.0 of 10

    The bag model in the large-N_c limit produces theoretically consistent EMT form factors and densities for the nucleon that satisfy general requirements.

  7. Three-dimensional imaging of hadrons with hard exclusive reactions: advances in experiment, theory, phenomenology, and lattice QCD

    hep-ph 2025-12 unverdicted novelty 2.0 of 10

    A community white paper reviewing GPD-based 3D imaging of hadrons — experiment, theory, phenomenology, lattice QCD — and the roadmap toward precision tomography at JLab, COMPASS, J-PARC, and future electron-ion colliders.
