abstract

In this paper we perform the first simultaneous QCD global analysis of data from semi-inclusive deep inelastic scattering, Drell-Yan, $e^+e^-$ annihilation into hadron pairs, and proton-proton collisions. Consequently, we are able to extract a universal set of non-perturbative functions that describes the observed asymmetries in these reactions. The outcome of our analysis indicates single transverse-spin asymmetries in high-energy collisions have a common origin. Furthermore, we achieve the first phenomenological agreement with lattice QCD on the up and down quark tensor charges.

  1. Transverse Charge Distribution as a Probe of Nucleon Transversity

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A charge-flow measurement built only from track angles and charge signs contains a leading-twist chiral-odd dipole that matches the charge-weighted Collins moment, giving enhanced transversity-sensitive asymmetries.

  2. Twist-3 effects in fully inclusive jet production from $e^+e^-$ annihilation

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Twist-3 corrections to e+e- -> hadron + inclusive jet are derived including weak interactions, yielding two azimuthal asymmetries that can expose the Collins fragmentation function at future colliders.

  3. The 3D structure of the Nucleon in momentum space: TMD phenomenology

    hep-ph 2025-01 conditional novelty 2.0 of 10

    A review showing unpolarized quark TMD fits now reach collinear-PDF-like precision, while polarized and gluon TMDs remain less constrained.

  4. Parton Distribution Functions and their Generalizations

    hep-ph 2025-07 unverdicted novelty 1.0 of 10

    A textbook-style introduction to the definitions, QCD properties, experimental access, and current phenomenological status of PDFs and their generalizations.
