Provides a method to extract the gluon Sivers function from experimental data.

Enhances understanding of gluon transverse momentum distributions.

Abstract

We present a recent calculation of the single spin asymmetry in inclusive photoproducton of $J/\psi$ at the future EIC, that can be used to probe the gluon Sivers function.
