Color fluctuation phenomena in $\gamma A$ collisions at the LHC

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 ($\rho$ -meson photoproduction)  and in the hard regime ($J/\psi$ photoproduction). We make CF based  predictions for the distribution...

description 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 ($\rho$ -meson photoproduction)  and in the hard regime ($J/\psi$ photoproduction). We make CF based  predictions for the distribution over the number  of wounded nucleons $\nu$ in the inelastic photon--nucleus scattering.  We show that CFs lead to a dramatic enhancement of this distribution at $\nu=1$ and large $\nu > 10$. Our predictions can be tested in proton--nucleus and nucleus--nucleus ultraperipheral collisions.
