Description
We study the various transverse-momentum-dependent (TMD) gluon distributions entering the cross section for forward di-jet production in dilute-dense collisions. For each TMD distribution we identify their operator definitions at small $x$ and finite $N_c$ as correlators of Wilson lines. With the result, we show the equivalence between the nearly back-to-back limit of the Color Glass Condensate cross section and the small-$x$ limit of the TMD factorization, at finite $N_c$. We obtain an analytical result for the gluon distributions in the Golec-Biernat-Wusthoff model, their perturbative behavior at large transverse momentum in the McLerran-Venugopalan model, and, numerically, their JIMWLK evolution towards small $x$. We observe geometric scaling regime for all the TMDs after some evolution.
