Single Spin Asymmetry in $e+p^\uparrow \rightarrow e+J/\psi+X$.

R. Godbole, A. Misra, A. Mukherjee & V. Rawoot
We report on a recent investigation of the single spin asymmetry (SSA) in low virtuality electroproduction of $J/\psi$ in color evaporation model. We show that this can be used as a probe for the still unknown gluon Sivers function.
