Using the available data on deeply virtual Compton scattering (DVCS) off protons and utilizing neural networks enhanced by the dispersion relation constraint, we determine six out of eight leading Compton form factors in the valence quark kinematic region. Furthermore, adding recent data on DVCS off neutrons, we separate contributions of up and down quarks to the dominant form factor, thus paving the way towards a three-dimensional picture of the nucleon.

  1. Exclusive Quark and Gluon Dijet Production as Probes of GPDs at Collider Energies

    hep-ph 2026-07 unverdicted novelty 6.0 of 10

    Exclusive quark and gluon dijet electroproduction is analyzed in collinear factorization as a GPD probe, extending prior work with helicity GPDs and an electromagnetic channel, with HERA comparisons and EIC projections.

  2. Assessing the impact of the electron ion collider in China on Deeply Virtual Compton Scattering

    hep-ph 2025-12 conditional novelty 5.0 of 10

    Projected EicC DVCS asymmetry data would substantially reduce uncertainties on all leading-order Compton form factors, most strongly in the sea-quark region.
