This article reviews lattice QCD results for the light hadron spectrum. An overview of different
formulations of lattice QCD with discussions on the fermion doubling problem and …

Quantum field theory describes basic physical phenomena over an extremely wide range of
length or energy scales. Quantum fields exist in space and time, which can be approximated …

This book provides a broad introduction to gauge field theories formulated on a space-time
lattice, and in particular of QCD. It serves as a textbook for advanced graduate students, and …

In this paper we show that the apparent failure of QCD lattice perturbation theory to account
for Monte Carlo measurements of perturbative quantities results from choosing the bare …

Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce
a new quark smearing that allows us to maintain small statistical errors and good overlaps of …

We present an investigation of gauge-invariant smearing for Wilson fermions in quenched
lattice QCD on a 24 3× 48 lattice at β= 6.2. We demonstrate a smearing algorithm that allows …

We present a study of finite a and volume effects of the leptonic decay constant ƒ of heavy
pseudoscalar mesons in the static approximation. This study is performed on a number of …

A high statistics computation of the decay constant ƒ B is presented to study scaling and
finite size effects. Smooth wave functions for the B-meson allow to suppress excited state …

We discuss in general the construction of gauge-invariant nonlocal meson operators on the
lattice. We use such operators to study the P-and D-wave mesons as well as hybrid mesons …

We report on a lattice QCD calculation of the π N σ term, the scalar form factor, and< N| ss|
N>. The disconnected insertion part of σ π N is found to be 1.8±0.1 times larger than the …
