Sivers Asymmetry in $e+p^\uparrow \rightarrow e+J/ψ+X$ [PDF]
Asmita MukherjeeA 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.View original: http://arxiv.org/abs/1209.2774
