Description
We present exploratory analyses of the 3D gluon content of the proton via a study of polarized gluon TMDs at leading-twist, calculated in a spectator model for the parent nucleon. Our approach encodes a flexible parameterization for the spectator-mass density, suited to describe both moderate- and small-$x$ effects. We show preliminary results on the application of our gluon TMDs to reactions featuring the production of heavy-quarkonium states. All these developments are relevant in the investigation of gluon dynamics inside nucleons and nuclei, which represents a major goal of new-generation colliding machines, as the EIC, NICA-SPD, the HL-LHC and the FPF.
