abstract
We calculate azimuthal asymmetries in back-to-back production of $J/\psi$ and a photon in electron-proton scattering process at the future electron-ion collider (EIC) using TMD factorization framework. We consider the cases where the proton is unpolarized or transversely polarized. For the formation of $J/\psi$, non-relativistic QCD (NRQCD) is used. We find that the cross-section gets contribution from only one color octet state, as a result, the azimuthal modulations become independent of the long-distance matrix elements (LDMEs), and thus can be used to probe, in particular the gluon TMDs which are dominant in this kinematics. We show estimates of the upper bounds of different azimuthal asymmetries using the positivity bounds on TMDs. In addition, we show estimate of asymmetries using the Gaussian parametrization of the TMDs.

The impact of the TMD shape function on matching the transverse momentum spectrum in $J/\psi$ production at the EIC
A process-dependent soft-gluon term in the J/psi TMD shape function is needed to keep the matched cross-section and cos(2phi) asymmetry predictions physical at the EIC, which supports the analytic result of Boer et al...
