TL;DR: In this article, the first direct lattice-QCD calculation of the valence quark distribution in the pion has been performed within the large momentum effective theory framework, and the results are comparable with the results extracted from experimental data as well as from Dyson-Schwinger equation.

Abstract: Within the large momentum effective theory framework, we report the results of the first direct lattice-QCD calculation of the valence quark distribution in the pion. Our results are comparable
quantitatively with the results extracted from experimental data as well as from Dyson-Schwinger equation. Future calculations at physical pion mass and larger momentum will be able to discern
discrepancies in various existing analyses.

Flavor symmetry and the static potential with hypercubic blocking
TL;DR: The static potential measured on HYP smeared lattices agrees with the thin link potential at distances $r/ag~2$ and has greatly reduced statistical errors and will be used in forthcoming dynamical simulations of HYP staggered fermions.

TL;DR: It is shown that the parton physics related to correlations of quarks and gluons on the light cone can be studied through the matrix elements of frame-dependent, equal-time correlators in the large momentum limit.

TL;DR: In this paper, a symmetry preserving truncation of the Dyson-Schwinger equation was proposed to explain the long-range behavior of the strong interaction, and the pion was shown to exist simultaneously as a Goldstone mode and a bound state of strongly dressed quarks.

TL;DR: In this paper, a new staggered-quark action (HISQ) was proposed, which reduced one-loop taste exchange errors, no tree-level order error, and no tree level order error to leading order in the quark's velocity.

TL;DR: In this article, the authors present results from simulations of quantum chromodynamics with four flavors of quarks: u, d, s, and c. The simulations are performed with a one-loop Symanzik improved gauge action and the highly improved staggered quark action.
