Description
Although significant results were obtained concerning quark transverse-momentum dependent distribution functions (TMD PDFs), the deep knowledge on their formal properties being surrounded by a rich and wealthy phenomenology, the gluon-TMD field represents an almost uncharted territory. After a brief introduction of gluon TMD PDFs and their connection with spin studies, we report progresses done via model-dependent calculations of T-even and T-odd functions at leading twist. We then review the potential of new-generation colliding machines to catch the inner dynamics of gluons inside protons via (un)polarized TMD studies in heavy-quarkonium emissions.
