Abstract We investigate coherent photoproduction of light vector mesons in Pb–Pb ultraperipheral collisions using the color dipole approach. Our analysis incorporates the Glauber–Gribov formalism with a gluon shadowing correction modeled via an effective suppression factor RG. This factor is fitted to match experimental data from the deep inelastic structure function F2 (E665) and ρ meson photoproduction (ALICE), yielding optimal agreement with RG=0.85 at scale Mρ2/4=0.15 GeV2. Based on this framework, we provide predictions for coherent photoproduction of ground and excited states, including ρ(2S), ω(1S,2S), and ϕ(1S,2S), employing holographic wave functions for the vector mesons.
