The two-scale evolution of Collins-Soper-Sterman-type for the unintegrated PDF in the regime qT << mu is derived from the BFKL evolution in physical rapidity with longitudinal momentum conservation constraint in coordinate space form. Comparisons of analytic results with Monte-Carlo implementation of the evolution are also done. This work is a continuation of the calculation done in Phys. Rev. D 104, 054039 (2021).
