A measurement is presented of elastic Deeply Virtual Compton Scattering e^+ + p -> e^+ + photon + p at HERA using data taken with the H1 detector. The cross section is measured as a function of the photon virtuality, Q^2, and the invariant mass, W, of the gamma p system, in the kinematic range 2 < Q^2 < 20 GeV^2, 30 < W < 120 GeV and |t| < 1 GeV^2, where t is the squared momentum transfer to the proton. The measurement is compared to QCD based calculations.

    hep-ph 2026-05 unverdicted novelty 7.0 of 10

    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 2025-04 conditional novelty 6.0 of 10

    A light-cone meson-baryon model is used to compute the eight nonzero twist-3 generalized parton distributions of ubar and dbar sea quarks at zero skewness, plus the derived e(x) and orbital angular momentum.

    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.

  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.
