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 ( -meson photoproduction) and in the hard regime (J/ 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.
