Gluon Sivers Function and Single Spin Asymmetry in $e+p^{\uparrow }\to e+J/\psi +X$

Rohini M. Godbole, Anuradha Misra, Asmita Mukherjee +1

We propose measurement of transverse single spin asymmetry (SSA) in charmonium production as a probe of gluon Sivers function. We estimate SSA in low virtuality electroproduction o…
