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.
The abundant production of lepton pairs via $J/Psi$ creation at COMPASS, $pi ^pm , p^uparrow to J/Psi , X to ell^+ ell^- X$, allows a measurement of the transverse Single Spin Asymmetry generated by the Sivers effect. The crucial issue of the sign ch
We study inclusive $J/psi$ photoproduction at NLO at large $P_T$ at HERA and the EIC. Our computation includes NLO QCD leading-$P_T$ corrections, QED contributions via an off-shell photon as well as those from $J/psi$+charm channels. For the latter,
We study the inclusive J/psi production at large transverse momenta at lepton-hadron colliders in the limit when the exchange photon is quasi real, also referred to as photoproduction. Our computation includes the leading-P_T leading-v next-to-leadin
We estimate transverse single spin asymmetry (TSSA) in electroproduction of $J/psi$ for J-Lab and EIC energies. We present estimates of TSSAs in $J/psi$ production within generalized parton model (GPM) using recent parametrizations of gluon Sivers fu
Understanding various fundamental properties of nucleons and nuclei are among the most important scientific goals at the upcoming Electron-Ion Collider (EIC). With the unprecedented opportunity provided by the next-generation machine, the EIC might p
