First direct lattice-QCD calculation of the x -dependence of the pion parton distribution function [PDF]
Physical Review D, 2018 We present the first direct lattice-QCD calculation of the Bjorken-$x$ dependence of the valence quark distribution in the pion. Using large-momentum effective theory (LaMET), we calculate the boosted pion state with long Wilson link operators.

Fixed Scale Approach to Equation of State in Lattice QCD [PDF]
, 2009 A new approach to study the equation of state in finite-temperature QCD is proposed on the lattice. Unlike the conventional method in which the temporal lattice size $N_t$ is fixed, the temperature $T$ is varied by changing $N_t$ at fixed lattice scale ...

Analytical relation between quark confinement and chiral symmetry breaking in odd-number lattice QCD
EPJ Web of Conferences, 2014 To clarify the relation between confinement and chiral symmetry breaking in QCD, we consider a temporally odd-number lattice, with the temporal lattice size Nt being odd.

Hamiltonian effective field theory study of the $\mathbf{N^*(1535)}$ resonance in lattice QCD
, 2016 Drawing on experimental data for baryon resonances, Hamiltonian effective field theory (HEFT) is used to predict the positions of the finite-volume energy levels to be observed in lattice QCD simulations of the lowest-lying $J^P=1/2^-$ nucleon excitation.

QCD at Finite temperature and density with staggered and Wilson quarks [PDF]
, 2004 One of the most challenging issues in particle physics is to study QCD in extreme conditions. Precise determination of the QCD phase diagram on temperature $T$ and chemical potential $\mu$ plane will provide valuable information for quark-gluon plasma ...

Three pion spectrum in the I=3 channel from lattice QCD
, 2020 Three-body states are critical to the dynamics of many hadronic resonances. We show that lattice QCD calculations have reached a stage where these states can be accurately resolved.

Nucleon Spin and Momentum Decomposition Using Lattice QCD Simulations. [PDF]
Physical Review Letters, 2017 We determine within lattice QCD the nucleon spin carried by valence and sea quarks and gluons. The calculation is performed using an ensemble of gauge configurations with two degenerate light quarks with mass fixed to approximately reproduce the physical

Datagrids for lattice QCD [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006 Abstract As the need for computing resources to carry out numerical simulations of Quantum Chromodynamics (QCD) formulated on a lattice has increased significantly, efficient use of the generated data has become a major concern. To improve on this, groups plan to share their configurations on a worldwide level within the International Lattice ...
