Abstract: In deeply inelastic lepton-nucleus scattering (DIS), the average jet transverse momentum is broadened because of the multiple scattering in the nuclear medium. The size of jet broadening is proportional to the multiparton correlation functions inside nuclei. We show that, at leading order, jet broadening in DIS and nuclear enhancement in a dijet momentum imbalance and averaged Drell-Yan transverse momentum square, $〈{q}_{T}^{2}〉,$ share the same four-parton correlation functions. We argue that jet broadening in DIS provides an independent measurement of the four-parton correlation functions and a test of the QCD treatment of multiple scattering.
