abstract

We present the extraction of unpolarized transverse momentum dependent parton distributions functions (TMDPDFs) and Collins-Soper kernel from the fit of Drell-Yan and weak-vector boson production data. The TMDPDF are parameterized, as commonly done, using their (large transverse momentum) asymptotic matching to PDF. The analysis is done at the next-to-next-to-next-to-next-to leading logarithmic accuracy (N$^4$LL) (performed only approximately because PDF evolution is known so far at next-to-next-to leading order (NNLO)). The non-perturbative model used for TMDPDF is flavor dependent to reduce the colllinear PDF bias. The estimation of uncertainties is done with the replica method and, for the first time, it includes the propagation of uncertainties due to the collinear distributions.

  1. Soft background fields at next-to-leading power in transverse momentum dependent SIDIS with jets

    hep-ph 2025-07 conditional novelty 7.0 of 10

    New next-to-leading-power factorization for SIDIS with jets from a background-field method with explicit soft modes, including operator-level definitions of twist-3 TMDs free of rapidity and endpoint divergences.

  2. Dihadron Angular Correlations in the $e^+e^-$ Collision

    hep-ph 2025-06 conditional novelty 7.0 of 10

    The paper derives the first complete O(alpha_s^2) analytic QCD corrections to the dihadron angular separation distribution in e+e- annihilation, with verified cancellation of infrared poles.

  3. Symbolic Extraction of Non-Perturbative Transverse-Momentum-Dependent Distributions from Drell-Yan Data

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Symbolic regression on a factorized NN fit to 482 Drell–Yan points yields a 9-constant analytical non-perturbative TMD with χ²/ndf≈1.04 and a retained x–b_T cross term.

  4. Impact of Z-boson transverse-momentum resummation on PDF determination

    hep-ph 2026-07 conditional novelty 6.0 of 10

    N3LL' resummation is required to reconcile the 13 TeV ATLAS Z-pT spectrum with global PDF fits, but lowering the pT cut below 30 GeV is not yet supported.

  5. New insights from the flavor dependence of quark transverse momentum distributions in the pion

    hep-ph 2025-09 conditional novelty 6.0 of 10

    First flavor-dependent extraction of unpolarized quark TMDs in the pion, finding a wider transverse momentum tail for valence d quarks than for sea quarks, with large uncertainties.

  6. Assessing the sensitivity of Energy-Energy Correlations in $e^+e^-$ annihilation to TMD dynamics

    hep-ph 2025-07 conditional novelty 6.0 of 10

    At N4LL accuracy, a global fit to all available e+e- energy-energy correlation data shows the data are insensitive to the Collins-Soper kernel and alpha_s, contradicting a recent extraction claim.

  7. MATRIX HAWAII: PineAPPL interpolation grids with MATRIX

    hep-ph 2025-06 accept novelty 6.0 of 10

    Matrix Hawaii provides a public interface between PineAPPL and MATRIX that generates interpolation grids at NNLO QCD + NLO EW accuracy for a range of LHC processes, with sub-permille interpolation errors.
