We show that for both quarks and gluons there are eight generalized parton distributions in the proton: four which conserve parton helicity and four which do not. We explain why time reversal invariance does not reduce this number from eight to six, as previously assumed in the literature.

  1. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 7.0

    Calculations of di-meson photoproduction amplitudes at leading order show cross sections up to 100 times larger than single-meson cases, enabling better GPD extraction.

  2. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 6.0

    Computes LO amplitudes for di-meson photoproduction channels sensitive to quark GPDs and reports high cross sections suitable for GPD studies at JLab energies.

    hep-ph 2025-12 unverdicted novelty 2.0

    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.
