abstract

We present an extraction of unpolarised Transverse-Momentum-Dependent Parton Distribution Functions based on Drell-Yan production data from different experiments, including those at the LHC, and spanning a wide kinematic range. We deal with experimental uncertainties by properly taking into account correlations. We include resummation of logarithms of the transverse momentum of the vector boson up to N$^3$LL order, and we include non-perturbative contributions. These ingredients allow us to obtain a remarkable agreement with the data.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Electromagnetic structure of charged and neutral strange vector mesons

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Covariant NJL calculations give K*+ charge radius 0.45 fm² and magnetic moment 2.67 μ_N, and K*0 radius −0.04 fm² and moment 0.032 μ_N.
