abstract

We present an unquenched calculation of the quark propagator in Landau gauge with 2+1 flavors of dynamical quarks. We use configurations generated with an improved staggered (``Asqtad'') action by the MILC collaboration. This quark action has been seen to have excellent rotational symmetry and scaling properties in the quenched quark propagator. Quenched and dynamical calculations are performed on a $20^3\times 64$ lattice with a nominal lattice spacing of $a = 0.125$ fm. The matched quenched and dynamical lattices allow us to investigate the relatively subtle sea quark effects, and even in the quenched case the physical volume of these lattices gives access to lower momenta than our previous study. We calculate the quark mass function and renormalization function for a variety of valence and sea quark masses.

  1. Pion Distribution Amplitudes from Functional QCD

    hep-ph 2026-07 conditional novelty 7.0 of 10

    The pion DA computed from functional QCD via LaMET has ⟨ξ²⟩_π = 0.267 (no quoted error), consistent with sum rules and DSE/BSE and 0.8σ below the lattice-LaMET value 0.300(41).

  2. Gauge-Invariant Off-Shell Mass

    hep-th 2026-07 conditional novelty 6.5 of 10

    A segment-local Ward–Takahashi cancellation makes the fermion self-energy equal to its Feynman-gauge value off shell, yielding a gauge-invariant, on-shell-renormalized mass function m(q).

  3. Scalar diquarks in the QCD vacuum

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    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...

  4. Toward precise $\xi$ gauge fixing for the lattice QCD

    hep-lat 2025-09 conditional novelty 6.0 of 10

    An empirical precision-extrapolation method reproduces the ξ-dependent RI/MOM renormalization constants of quark bilinear operators on the lattice to 0.2-0.3% for ξ up to 1.

  5. The equation of state and surface tension of QCD in the first order phase transition region

    hep-ph 2025-07 conditional novelty 5.0 of 10

    A parametrized order-parameter model yields the equation of state, spinodal boundaries, and surface tension for the first-order QCD phase transition.

  6. Electroexcitation of Nucleon Resonances and the Emergence of Hadron Mass

    hep-ph 2025-05 conditional novelty 2.0 of 10

    A review argues that Jefferson Lab electroproduction data on nucleon resonances, analyzed with continuum Schwinger methods, confirm a momentum-dependent dressed quark mass, the essence of emergent hadron mass.
