We develop an off-shell extention of the Regge-eikonal approach which automatically takes into account off-shell unitarity. We argue that exclusive vector-meson production cross-sections measured at HERA can be fairly described with classical universal Regge trajectories. No extra ``hard'' trajectories of high intercept are needed for that.

  1. The OPE-Regge Transition in $J/\psi$ Photoproduction

    hep-ph 2026-04 unverdicted novelty 5.0

    Leading-twist convolution with small-x singular PDFs matches threshold J/ψ data but requires eikonal unitarization fitted to HERA to cover the full energy range, with the dispersive real part dominating near threshold.
