We present in this letter the first systematic feasibility study of accessing generalised parton distributions of the pion at an electron-ion collider through deeply virtual Compton scattering at next-to-leading order. It relies on a state-of-the-art model, able to fulfil by construction all the theoretical constraints imposed on generalised parton distributions. Strikingly, our analysis shows that quarks and gluons interfere destructively and that gluon dominance could be spotted by a sign change of the DVCS beam spin asymmetry.

  1. Extraction of Pion Unpolarized Quark and Gluon Generalized Parton Distributions using Deep Neural-Networks

    hep-ph 2026-08 conditional novelty 6.0 of 10

    A DNN fit to pion form-factor and lattice data produces quark and gluon GPDs; quark results agree with lattice, gluon results rely on a fitted normalization factor.

  2. 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.

  3. Mapping spatial distributions within pseudoscalar mesons

    hep-ph 2024-12 conditional novelty 5.0 of 10

    A new analytic parametrization of meson valence-quark GPDs yields spatial charge and mass distributions and radius ratios for pions, kaons and heavy-light mesons.

  4. 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.
