Abstract

Determining the dipole model unintegrated gluon distribution (UGD) is a problem of significant interest in small-. x physics. Here we relate the dipole gluon distribution to the angular correlation function of the process pA→ℓℓπ0X, which provides a clean probe of the nuclear structure, and compute numerical predictions for the correlation function based on three models for the UGD: the GBW model, and BK evolution with fixed and running coupling. With all three models, the correlation exhibits an interesting double-peak structure, but the BK evolution is necessary to reproduce the near-side emission peak.
