摘要：
Within the framework of nonrelativistic QCD (NRQCD) effective field theory, we study the leptoproduction of J/jr at next-to-leading order in perturbative QCD for both unpolarized and polarized electron-ion collisions. We demonstrate that the J/jr-tagged deep inelastic scattering in the future ElectronIon Collider can be served as a golden channel for reasons including constraining NRQCD long-distance matrix elements, probing the nuclear gluon distribution functions, as well as investigating the gluon helicity distribution inside a longitudinal polarized proton.
