Joint ECFA-NuPECC-APPEC Workshop “Synergies between the EIC and the LHC”

Transverse momentum dependent parton distribution functions (TMDs) encode essential information on the transverse motion of partons inside nucleons, as well as their spin-orbit correlations. In this talk I will show how, by looking at the azimuthal asymmetries in the inclusive production of pairs of vector quarkonia ($J/\psi$, $\psi(2S)$, $\Upsilon$ mesons), one can probe different TMDs. In...

We present a phenomenological analysis for hadron-in-jet production in (un)polarized $pp$ collisions within a TMD approach, based on recent extractions of TMD fragmentation functions (TMD FFs) from SIDIS and $e^+e^-$ processes. The general agreement of our estimates with the available data corroborates the hypothesis of the TMD factorization for such processes as well as of the universality of...
