We present a novel method of extraction of the Collins-Soper kernel directly from the comparison of diﬀerential cross-sections measured at diﬀerent energies. Using this method, we analyze the pseudo-data generated by the CASCADE event generator and extract the Collins-Soper kernel predicted by the parton-branching model in the wide range of transverse distances. The procedure can be applied, with minor modiﬁcations, to the real measured data for Drell-Yan and SIDIS processes.
