Description
We explore how the positivity of the $P_T$-integrated $\eta_c$-hadroproduction cross section computed at NLO in $\alpha_s$ can set up constraints on the $x$ dependence of both gluon PDFs and TMDs at low scales. We also discuss the phenomenological implications on other quarkonium-production cross sections computed at NLO in both collinear and TMD factorisations.
