abstract
We present the distribution of unpolarized quarks in a transversely polarized proton in three-dimensional momentum space. Our results are based on consistent extractions of the unpolarized and Sivers transverse momentum dependent parton distributions (TMDs).

Analytical cross sections and Sivers asymmetry predictions are presented for double quarkonium production via quark-antiquark annihilation at fixed-target experiments, showing a 10-15% asymmetry at COMPASS and small negative asymmetries at LHC fixed-target energies.
Global QCD analysis extracts genuine twist-three PDFs from g2, d2 and SIDIS asymmetries, confirming their universality and factorization validity.
