Transverse single spin asymmetry in $p+p^\uparrow \rightarrow J/\psi +X$

We present estimates of transverse single spin asymmetry (TSSA) in p+p↑→J/ψ+X within the color evaporation model of charmonium production in a generalized parton model (GPM) framework, using the recently obtained best fit parameters for the gluon Sivers function (GSF) extracted from PHENIX data on T...

description We present estimates of transverse single spin asymmetry (TSSA) in p+p↑→J/ψ+X within the color evaporation model of charmonium production in a generalized parton model (GPM) framework, using the recently obtained best fit parameters for the gluon Sivers function (GSF) extracted from PHENIX data on TSSA in p+p↑→π0+X at midrapidity. We calculate asymmetry at s=200  GeV, and compare the results with PHENIX data on TSSA in the process p+p↑→J/ψ+X. We also present estimates for asymmetry at s=115  GeV corresponding to the proposed fixed target experiment AFTER@LHC and at s=500  GeV corresponding to the higher RHIC energy. Finally, we investigate the effect of the transverse momentum dependent (TMD) evolution of the densities involved, on the asymmetry.
