Sivers asymmetry in inelastic J/ leptoproduction at the EIC
Abstract
We study the Sivers asymmetry in inelastic J/ leptoproduction, ep e+ J/+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/ formation the non-relativistic QCD (NRQCD) framework is adopted. Predictions for unpolarized cross sections and maximized Sivers asymmetries at EIC energies are given.
