This article is a pedagogical exploration of the nonperturbative issues entwining lattice
gauge theory, anomalies, and chiral symmetry. After briefly reviewing the importance of …

We show that it is possible to improve the chiral behaviour and the approach to the
continuum limit of correlation functions in lattice QCD with Wilson fermions by taking …

Quenched QCD simulations on three volumes 8 3×, 12 3× and 16 3× 32 and three couplings
β= 5.7, 5.85 and 6.0 using domain wall fermions provide a consistent picture of quenched …

We present a calculation of the strangeness and charmness contents⟨ N| s¯ s| N⟩ and⟨ N|
c¯ c| N⟩ of the nucleon from dynamical lattice QCD with 2+ 1 flavors. The calculation is …

Using the constrained-curve fitting method and overlap fermions with the lowest pion mass
at 180 MeV, we observe that the masses of the first positive and negative parity excited …

We study the a0 and sigma mesons with the overlap fermion in the chiral regime with the
pion mass as low as 182 MeV in the quenched approximation. After the eta'pi ghost states …

The overlap fermion propagator is calculated on 2+ 1 flavor domain-wall fermion gauge
configurations on 16 3× 32, 24 3× 64 and 32 3× 64 lattices. With hyper-cubic (HYP) …

We consider solution of multiply shifted systems of nonsymmetric linear equations, possibly
also with multiple right-hand sides. First, for a single right-hand side, the matrix is shifted by …

We present a calculation of hadron magnetic polarizability using the techniques of lattice
QCD. This is carried out by introducing a uniform external magnetic field on the lattice and …

We calculate the quark orbital angular momentum of the nucleon from the quark energy-
momentum tensor form factors on the lattice with the quenched approximation. The …
