Strong A dependence observed in diffractive deep inelastic scattering.

Impact parameter effects are crucial for understanding high energy nuclear interactions.

Abstract

We show that the enhancement of the saturation scale in large nuclei relative to the proton is significantly influenced by the effects of quantum evolution and the impact parameter dependence of dipole cross sections in high energy QCD. We demonstrate that there is a strong A dependence in diffractive deeply inelastic scattering and discuss its sensitivity to the measurement of the recoil nucleus.
