Description
We study the photoproduction of light vector mesons considering both
the proton and the nucleus as targets. Utilizing the dipole picture
and wave functions obtained via AdS/QCD, we were able to describe the
HERA $\gamma p$ data and extend the analysis to the nuclear case by
employing the Glauber–Gribov formalism. This formalism is supplemented
by an effective nuclear suppression factor, $R_G$, which accounts for
the gluon shadowing correction. Our results are compared to recent $Pb
Pb \rightarrow \rho Pb Pb$ data from the LHC, and predictions for
other light vector mesons are presented.
