QCD on an Infinite Lattice

open access: yesCommunications in Mathematical Physics, 2013
We construct a mathematically well--defined framework for the kinematics of Hamiltonian QCD on an infinite lattice in $\R^3$, and it is done in a C*-algebraic context. This is based on the finite lattice model for Hamiltonian QCD developed by Kijowski, Rudolph e.a.. To extend this model to an infinite lattice, we need to take an infinite tensor product

String breaking in lattice QCD [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1999
The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD.

Analytical relation between quark confinement and chiral symmetry breaking in odd-number lattice QCD

open access: yesEPJ 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.

Maximum Entropy Analysis of the Spectral Functions in Lattice QCD [PDF]

open access: yes, 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 ...

Hot QCD on the Lattice [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2007
We review lattice results that probe properties of high temperature QCD at different length scales and can help to elucidate its non-perturbative structure. We examine the flavor and chemical potential dependence of electric and magnetic screening lengths as well as the QCD equation of state.

Hamiltonian effective field theory study of the $\mathbf{N^*(1535)}$ resonance in lattice QCD

open access: yes, 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.

Strangeness in lattice QCD [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2001
The status of lattice calculations in the light hadron sector is reviewed. Special emphasis is given to recent lattice determinations of the mass of the strange quark. The impact of non-perturbative renormalization and control over lattice artefacts on the attainable precision is discussed in detail. Furthermore the influence of dynamical quark effects

Visualization of semileptonic form factors from lattice QCD

open access: yes, 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 meets experiment in hadron physics [PDF]

open access: yes, 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 ...
