We study inclusive $J/\psi$ photoproduction at NLO at large $P_T$ at HERA and the EIC. Our computation includes NLO QCD leading-$P_T$ corrections, QED contributions via an off-shell photon as well as those from $J/\psi$+charm channels. For the latter

International audience; We perform the first next-to-leading order computation of the γ(*)→V (ρ,ϕ,ω) exclusive impact factor in the QCD shock-wave approach and in the most general kinematics. This paves the way to the very first quantitative st

Physical review / D 63(7), 079902 (2001). doi:10.1103/PhysRevD.65.079902
As a first step towards the computation of the NLO corrections to the photon impact factor in the $\gamma^*\gamma^* \to \gamma^* \gamma^*$ scattering process, we calculate

Parametrization of $F_2^\gamma$ at low $Q^2$ and of $\sigma_{\gamma \gamma}$ and $\sigma_{\gamma^* \gamma}$ at high-energies

8 pp. (2000).
A parametrization of the real photon structure function $F_2^\gamma$ in the low $Q^2$, low $x$ region is formulated. It includes both the vector meson dominance (VMD) and the QCD components, the latter suitably extrapolated to the
