Abstract
We study the Sivers asymmetry in inelastic $J/\psi$ leptoproduction, $ep^\uparrow \to e+ J/\psi+X$, within a transverse momentum dependent scheme, the so-called generalized parton model (GPM). The effects of final-state interactions are properly taken into account by employing the color-gauge invariant GPM (CGI-GPM). For the $J/\psi$ formation the non-relativistic QCD (NRQCD) framework is adopted. Predictions for unpolarized cross sections and maximized Sivers asymmetries at EIC energies are given.

Report
This paper discusses J/psi sivers asymmetries in particular in the context of EIC kinematics, with interesting results for the analyzing power of this channel as a probe of the gluon sivers function. The Journal's acceptance criteria for these proceedings are met.
