A note on the power divergence in lattice calculations of amplitudes at

Maarten Golterman, C. -J. David Lin, Elisabetta Pallante

In this note, we clarify a point concerning the power divergence in lattice calculations of decay amplitudes. There have been worries that this divergence might…

Center Dominance in SU(2) Gauge-Higgs Theory

Roman Bertle, Manfried Faber, Jeff Greensite +1

We study the SU(2) gauge-Higgs system in D=4 dimensions, and analyze the influence of the fundamental-representation Higgs field on the vortex content of the gauge field. It is sho…

On the phase diagram of quenched QCD with Wilson fermions

Maarten Golterman

In this talk, I reported on recent work on the Aoki phase diagram for quenched QCD with two flavors of Wilson fermions. Part of this work was done in collaboration with Yigal Shami…

Adventures in Coulomb Gauge

J. Greensite, S. Olejnik

We study the phase structure of SU(2) gauge theories at zero and high temperature, with and without scalar matter fields, in terms of the symmetric/broken realization of the remnan…

Analytic estimates of quenched penguins

Maarten Golterman, Santi Peris

When we embed the strong penguin operator Q_6 in the quenched theory, it does not remain a singlet under right-handed chiral transformations. As a consequence, more low-energy cons…

Localization in lattice QCD (with emphasis on practical implications)

Maarten Golterman, Yigal Shamir

When Anderson localization takes place in a quenched disordered system, a continuous symmetry can be broken spontaneously without accompanying Goldstone bosons. Elaborating on this…

Analytic estimates for penguin operators in quenched QCD

Maarten Golterman, Santi Peris

Strong penguin operators are singlets under the right-handed flavor symmetry group SU(3)_R. However, they do not remain singlets when the operator is embedded in (partially) quench…

Localization in Lattice QCD

Maarten Golterman, Yigal Shamir

In this paper, we examine the phase diagram of quenched QCD with two flavors of Wilson fermions, proposing the following microscopic picture. The super-critical regions inside and…

Coulomb Energy, Vortices, and Confinement

J. Greensite, S. Olejnik

We estimate the Coulomb energy of static quarks from a Monte Carlo calculation of the correlator of timelike link variables in Coulomb gauge. We find, in agreement with Cucchieri a…

The Confinement Problem in Lattice Gauge Theory

J. Greensite

I review investigations of the quark confinement mechanism that have been carried out in the framework of SU(N) lattice gauge theory. The special role of Z(N) center symmetry is em…
