abstract

We present a model of exclusive $\phi$-meson lepto-production $ep \to e'p'\phi$ near threshold which features the strangeness gravitational form factors of the proton. We argue that the shape of the differential cross section $d\sigma/dt$ is a sensitive probe of the strangeness D-term of the proton.

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Spin-resummed holographic QCD unifies near-threshold GFF and high-energy pomeron regimes for heavy quarkonium photoproduction and shows fixed-spin GFF extraction is not controlled.

    hep-ph 2025-06 conditional novelty 6.0 of 10

    Using a light-front Hamiltonian with three-quark and three-quark-plus-gluon Fock sectors, the authors extract quark and gluon gravitational form factors and find a proton mass decomposition of 31.5% quark energy, 34.7...

  3. Gravitational form factors of the nucleon in the Skyrme model based on scale-invariant chiral perturbation theory

    hep-ph 2025-07 conditional novelty 5.0 of 10

    A Skyrme model with a dilaton field attributes the proton's negative internal pressure and confining force to the gluonic scale anomaly, and reproduces the lattice QCD D(t) form factor.
