Description

After a brief introduction to QCD at small $x_{Bj}$ we show that the wave function of a hadron or nucleus at small $x$ contain a large number of gluons. We argue that this kinematics dominates high energy scattering and that the hadron/nucleus can be describes as a strong classical color field from which a parton in the projectile scatters. We apply this formalism to particle production in Deep Inelastic Scattering off of protons and nuclei as well as to proton-nucleus collisions at RHIC and the LHC and elucidate the connections to scattering of cosmic rays.
