Dramatic progress has been made over the last decade in the numerical study of quantum
chromodynamics (QCD) through the use of improved formulations of QCD on the lattice …

The consideration of quantum fields defined on a spacetime lattice provides computational
techniques which are invaluable for studying gauge theories nonperturbatively from first …

We study the leading discretization errors for staggered fermions by first constructing the
continuum effective Lagrangian, including terms of O (a 2), and then constructing the …

An upgraded analysis of ɛ, xd and ɛ′/ɛ, using the latest determinations of the relevant
experimental and theoretical parameters, is presented. Using the recent determination of the …

We report the results of a calculation of the K→ π π matrix elements relevant for the Δ I= 1/2
rule and ε′/ε in quenched lattice QCD using domain wall fermions at a fixed lattice spacing …

We present results for the matrix elements of a variety of four-fermion operators calculated
using quenched Wilson fermions. Our simulations are done on 170 lattices of size 32 3× 64 …

Lattice QCD should allow a derivation of the ΔI= 1 2 rule from first principles, but numerical
calculations to date have been plagued by a variety of problems. After a brief review of these …

We compute the h¯ c (pseudo) scalar,(axial-) vector and (axial-) tensor susceptibilities as a
function of u= mc/mh between u= mc/mb and u= 0.8 using fully relativistic lattice QCD …

We examine the renormalization of flavor-diagonal vector currents in lattice QCD with the
aim of understanding and quantifying the systematic errors from nonperturbative artifacts …

We study taste and Euclidean rotational symmetry violation for staggered fermions at
nonzero lattice spacing using staggered chiral perturbation theory. We extend the staggered …
