Probing the Sivers asymmetries through $rm J/psi$ photoproduction in $rm p^uparrow p$ collision with forward proton tagging

In this paper we probe the Sivers asymmetries through $rm J/psi$ photoproduction in $rm p^uparrow p$ collision within the non-relativistic QCD framework, based on color octet model and the Transverse Momentum Dependent Parton Distributions (TMDs). Both the DGLAP evolution and the TMD evolution are included. The intensity and the sign of the Sivers asymmetry is strongly related on evolution model used to investigate the Gluon Sivers Function (GSF). A sizable asymmetry is obtained as a function of the rapidity, $rm log{(x_{gamma})}$ or $rm log{(x_{g})}$ dependence using a recent parametrization of GSF at the RHIC and AFTER@LHC experiments with the LHC planned forward detector acceptances.
