Abstract

We explain that color fluctuations (CFs) in the light-cone photon wave function lead to much stronger shadowing in the coherent production both in the soft regime (ρ -meson photoproduction) and in the hard regime (J/ψ photoproduction). We make CF based predictions for the distribution over the number of wounded nucleons ν in the inelastic photon–nucleus scattering. We show that CFs lead to a dramatic enhancement of this distribution at ν = 1 and large ν > 10. Our predictions can be tested in proton–nucleus and nucleus–nucleus ultraperipheral collisions.
