Sub-eikonal corrections to dipole structure functions F_L, F_T and the g1-related asymmetry are derived in a gauge-invariant dipole operator basis, with F_L shown to be finite and the others logarithmically divergent.

Unpolarized GPDs and GTMDs at small x with non-zero skewness are expressed via the dipole amplitude N and odderon O with modified rapidity Y = ln min{1/|x|, 1/|ξ|}.
The n-particle gluon radiation spectrum in shockwave scattering is a generalized Susskind-Glogower squeezed coherent state, and multi-graviton radiation follows similarly via double copy, with feasible large squeezing parameters ~ln(n_bar) leading to enhanced quantum noise in gravitational wave sp
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.
After Q_s-adaptive coarse graining, conditional gluon Husimi momentum distributions from fixed-coupling SO(3)-BK evolution collapse as functions of k/Q_s(Y,b), with conditional entropy growing at unit slope versus ⟨ln Q_s²⟩.
Derives Reggeized quark operator from Wilson lines and its nonlinear rapidity RG evolution in QCD, recovering known Regge trajectories in dilute and large-Nc limits after signature projection.
Collinearly improved IMST BK evolution moves the elliptic node and reshapes the rapidity and hard-scale dependence of coherent diffractive dijet ⟨cos2φ⟩ relative to LO BK, not just a normalization shift.
One-loop quark TMD calculation in projectile light-cone gauge produces CSS evolution equations whose rapidity structure is compared to the target gauge result.
Replacing the rapidity argument of the dipole amplitude with ln min{1/|x|, 1/|ξ|} and refining initial conditions for non-linear evolution can eliminate two R-factors in small-x shockwave calculations.
Review summarizing observed cold nuclear matter modifications in hadron-nucleus collision data and proposing experimental strategies for the EIC to clarify underlying QCD mechanisms.

Squeezed-state radiation in shockwave scattering: QCD-Gravity double copy
The n-particle gluon radiation spectrum in shockwave scattering is a generalized Susskind-Glogower squeezed coherent state, and multi-graviton radiation follows similarly via double copy, with feasible large squeezing parameters ~ln(n_bar) leading to enhanced quantum noise in gravitational wave sp
