abstract
We present first calculations of the fluctuating gluon distribution in a proton as a function of impact parameter and rapidity employing the functional Langevin form of the JIMWLK renormalization group equation. We demonstrate that when including effects of confinement by screening the long range Coulomb field of the color charges, the evolution is unitary. The large-x structure of the proton, characterized by the position of three valence quarks, retains an effect on the proton shape down to very small values of x. We determine the dipole scattering amplitude as a function of impact parameter and dipole size and extract the rapidity evolution of the saturation scale and the proton radius.

Comparison of SMASH and McDipper initial condition models shows agreement in longitudinal deposition at lower energies but substantial differences in energy and baryon deposition at higher center-of-mass energies.
Predictions for vector meson production in light-nucleus UPCs show t-differential observables sensitive to nuclear structure models and saturation suppression that grows with nuclear mass and collision energy.
