A process-dependent soft-gluon term in the J/psi TMD shape function is needed to keep the matched cross-section and cos(2phi) asymmetry predictions physical at the EIC, which supports the analytic result of Boer et al. and suggests a node-based test for the gluon TMD sign.

The impact of the TMD shape function on matching the transverse momentum spectrum in $J/\psi$ production at the EIC
A process-dependent soft-gluon term in the J/psi TMD shape function is needed to keep the matched cross-section and cos(2phi) asymmetry predictions physical at the EIC, which supports the analytic result of Boer et al. and suggests a node-based test for the gluon TMD sign.
