Process dependence of the gluon Sivers function in $p^{\uparrow }p\to J/\psi +X$ within a TMD approach in NRQCD

Umberto D'Alesio, Luca Maxia, Francesco Murgia +2

We consider the transverse single-spin asymmetry (SSA) for $J/\psi$ production in $p^{\uparrow }p\to J/\psi +X$ within a TMD approach in non-relativistic QCD. Extending a previous study […
