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.

$J/\psi$ Photoproduction from Threshold to HERA: Leading-Twist Convolution, Small-$x$ Pathology, and Eikonal Unitarization
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.
