abstract
We study the transverse momentum dependent (TMD) parton distributions at small-x in a consistent framework that takes into account the TMD evolution and small-x evolution simultaneously. The small-x evolution effects are included by computing the TMDs at appropriate scales in terms of the dipole scattering amplitudes, which obey the relevant Balitsky-Kovchegov equation. Meanwhile, the TMD evolution is obtained by resumming the Collins-Soper type large logarithms emerged from the calculations in small-x formalism into Sudakov factors.

Analytical CGC amplitudes and cross sections for forward g o q¯qg and g o ggg trijet production in pA collisions are obtained, with rapidity and collinear divergences shown to match JIMWLK and DGLAP evolution.
An IRC-safe azimuthal energy-flow cos2φ moment in DIS dijets linearly projects the elliptic gluon Wigner harmonic after a calculable kinematic subtraction.
A conservative BFKL-aware endpoint matching of the NLO forward jet vertex moves R21 toward CMS but does not simultaneously describe all five CMS azimuthal observables under the tested BLM/MOM prescriptions.
For the dipole gluon TMD, the Sudakov-limited maximum phase-space density of h_1^{⊥g} is 2 n_g^{max} ∼ 2 α_s^{-3/2} in the saturation region.
