Description
We perform an analysis of the BK evolution equation formulated in momentum space, supplemented by higher-order resummation corrections motivated by renormalization group improvements and the kinematical constraints. The equation is solved over a wide range of transverse momenta and longitudinal momentum fractions using GPU-optimized numerical computation. The solutions are fitted to HERA data, allowing us to extract the unintegrated gluon density over a broad momentum range. The pattern of the resulting saturation scale obtained from the gluon density shows behavior consistent with the expected QCD evolution map.
