Proton-Nucleus Scattering in the Color Glass Condensate

We present an alternative description of the proton-nucleus collision within the framework of the Color Glass Condensate (CGC). This is based on the eikonal approximation for three valence quarks in a projectile proton which propagate in the strong gauge field created by the target nucleus treated as the CGC. The similar construction was recently done for the C-odd Odderon exchange. This description directly allows us to compute the evolution of the scattering amplitude between a 3-quark state and the CGC. We show the evolution equations in the weak and strong field regimes, and discuss the effects of gluon saturation.
