Tree-level and one-loop collinear matching relations are computed for leading-power gluon TMD PDFs, yielding the first Wandzura-Wilczek approximation for the gluon worm-gear T distribution along with a closed-form mass correction series.
After including TMD evolution, the Sivers asymmetry in these J/ψ processes at EIC kinematics remains sizable and largely independent of LDME choices, providing a robust probe of the gluon Sivers function.
