Sivers Asymmetry in $e+p^{\uparrow }\to e+J/\psi +X$

Abstract

A recent investigation of the single spin asymmetry (SSA) in low virtuality electroproduction/photoproduction of $J/\psi$ in color evaporation model is presented. It is shown that the asymmetry is sizable and can be used as a probe for the still unknown gluon Sivers function.
