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 ...

The I = 1 pion–pion scattering amplitude and timelike pion form factor from Nf = 2 + 1 lattice QCD [PDF]
Nuclear Physics B, 2018 The elastic I = 1 p-wave ππ scattering amplitude is calculated together with the isovector timelike pion form factor using lattice QCD with N f = 2 + 1 dynamical quark flavors. Wilson clover ensembles generated by the Coordinated Lattice Simulations (CLS)

Charged multihadron systems in lattice QCD+QED [PDF]
Physical Review D, 2020 Systems with the quantum numbers of up to twelve charged and neutral pseudoscalar mesons, as well as one-, two-, and three-nucleon systems, are studied using dynamical lattice quantum chromodynamics and quantum electrodynamics (QCD+QED) calculations and ...

Lattice QCD with Ginsparg-Wilson fermions [PDF]
, 1999 Lattice QCD using fermions whose Dirac operator obeys the Ginsparg-Wilson relation, is perhaps the best known formulation of QCD with a finite cutoff. It reproduces all the low energy QCD phenomenology associated with chiral symmetry at finite lattice ...

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.

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.

, 2004 QCD at finite density presents specific challenges to lattice gauge theory. Nonetheless, a region of the QCD phase diagram up to moderately large baryon chemical potentials has been successfully explored on the lattice and new results and idea are ...

Perturbative Thermodynamics of Lattice QCD with Chiral-Invariant Four-Fermion Interactions [PDF]
, 1998 Lattice QCD with additional chiral-invariant four-fermion interactions is studied at nonzero temperature. Staggered Kogut-Susskind quarks are used. The four-fermion interactions are implemented by introducing bosonic auxiliary fields.

Light-Cone Parton Distribution Functions from Lattice QCD. [PDF]
Physical Review Letters, 2018 We extract parton distribution functions (PDFs) of the nucleon from lattice QCD using an ensemble of gauge field configurations simulated with light quark masses fixed to their physical values.
