Description
Vector meson eletroproduction is a key channel for probing the nucleon’s generalized parton distributions (GPDs), particularly the gluon contributions at lepton–hadron colliders such as HERA and the future EIC/EicC. In this talk, we present the next-to-next-to-leading order (NNLO) QCD radiative corrections to the leading-twist process γ* N → V N. The NNLO corrections are found to have a substantial impact. We also perform phenomenological studies using two well-known GPD models and compare the results with HERA experimental data.
