Small x dynamics of the unpolarised color dipole gluon TMD PDFs for all transverse momenta
This paper derives a closed-form expression for the unpolarized color dipole gluon TMD distribution across all transverse momenta by Fourier-Bessel transforming a general solution of the Balitsky-Kovchegov equation, revealing a characteristic inversion of x-ordering at the saturation scale that serves as a model-independent signature of gluon saturation.
