The quark mass function is computed both by solving the quark propagator Dyson-Schwinger equation and from lattice simulations implementing overlap and Domain-Wall fermion actions for valence and sea quarks, respectively. The results are confronted and seen to produce a very congruent picture, showing a remarkable agreement for the explored range of current-quark masses. The effective running-interaction is based on a process-independent charge rooted on a particular truncation of the Dyson-Schwinger equations in the gauge sector, establishing thus a link from there to the quark sector and inspiring a correlation between the emergence of gluon and hadron masses.

  1. Pion Distribution Amplitudes from Functional QCD

    hep-ph 2026-07 conditional novelty 7.0

    fRG-based functional QCD plus LaMET yields a saturated pion quasi-DA at Pz=4.5 GeV and a second moment ⟨ξ²⟩π=0.267, smaller than lattice-LaMET and consistent with other nonperturbative methods.

  2. Scalar diquarks in the QCD vacuum

    hep-ph 2026-06 unverdicted novelty 6.0

    A first-principles FRG approach to two-flavor QCD derives low-energy constants for the pion, sigma-meson and scalar diquark without parameters beyond QCD itself, including new diquark properties for color-superconduct...

  3. Radiative charmonium decays in a contact-interaction model with dynamical quark anomalous magnetic moment

    hep-ph 2026-04 unverdicted novelty 6.0

    Contact-interaction model with dynamical quark anomalous magnetic moment reproduces lattice QCD results for eta_c to gamma gamma and J/psi to gamma eta_c decays, consistent with 2026 data but not the 2024 measurement.

  4. Kaon Distribution Amplitudes from Euclidean Functional QCD

    hep-ph 2026-04 unverdicted novelty 5.0

    Kaon DA is single-peaked and asymmetric with moments ⟨ξ⟩_K = 0.020(3) and ⟨ξ²⟩_K = 0.253(12) after 1/P_z² and 1/P_z⁴ extrapolation of the quasi-DA.
