Maximum Entropy Analysis of the Spectral Functions in Lattice QCD [PDF]
, 2000 First principle calculation of the QCD spectral functions (SPFs) based on the lattice QCD simulations is reviewed. Special emphasis is placed on the Bayesian inference theory and the Maximum Entropy Method (MEM), which is a useful tool to extract SPFs ...

Chiral Fermions Algorithms In Lattice QCD
East European Journal of Physics, 2019 The theory that explains the strong interactions of the elementary particles, as part of the standard model, it is the so-called Quantum Chromodynamics (QCD) theory.

Visualization of semileptonic form factors from lattice QCD
, 2009 Comparisons of lattice-QCD calculations of semileptonic form factors with experimental measurements often display two sets of points, one each for lattice QCD and experiment.

Lattice QCD in Rotating Frames [PDF]
Physical Review Letters, 2013 We formulate lattice QCD in rotating frames to study the physics of QCD matter under rotation. We construct the lattice QCD action with the rotational metric and apply it to the Monte Carlo simulation. As the first application, we calculate the angular momenta of gluons and quarks in the rotating QCD vacuum.

Master integrals for two-loop QCD corrections to quark quasi PDFs
Journal of High Energy Physics, 2020 We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

The γπ → ππ anomaly from lattice QCD and dispersion relations
Journal of High Energy Physics, 2021 We propose a formalism to extract the γπ → ππ chiral anomaly F 3π from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a dispersive representation of the γ (*) π → ππ amplitude, whose main quark-mass ...

Existence of Chiral-Asymmetric Zero Modes in the Background of QCD-Monopoles [PDF]
, 1997 We study topological aspects of the QCD vacuum structure in SU(2) lattice gauge theory with the abelian gauge fixing. The index of the Dirac operator is measured by using the Wilson fermion in the quenched approximation.

Lattice QCD meets experiment in hadron physics [PDF]
, 2003 We review recent results in lattice QCD from numerical simulations that allow for a much more realistic QCD vacuum than has been possible before. Comparison with experiment for a variety of hadronic quantities gives agreement to within statistical and ...
