Reply to: `Comment on: " 't Hooft vertices, partial quenching, and rooted staggered QCD" '
Claude Bernard, Maarten Golterman, Yigal Shamir +1
We reply to Creutz's comments on our paper " 't Hooft vertices, partial quenching, and rooted staggered QCD." We show that his criticisms are incorrect and result from a misunderst…
Zero of the discrete beta function in SU(3) lattice gauge theory with color sextet fermions
Yigal Shamir, Benjamin Svetitsky, Thomas DeGrand
We have carried out a Schrodinger functional (SF) calculation for the SU(3) lattice gauge theory with two flavors of Wilson fermions in the sextet representation of the gauge group…
Effective field theories for QCD with rooted staggered fermions
Claude Bernard, Maarten Golterman, Yigal Shamir
Even highly improved variants of lattice QCD with staggered fermions show significant violations of taste symmetry at currently accessible lattice spacings. In addition, the "rooti…
't Hooft vertices, partial quenching, and rooted staggered QCD
Claude Bernard, Maarten Golterman, Yigal Shamir +1
We discuss the properties of 't Hooft vertices in partially quenched and rooted versions of QCD in the continuum. These theories have a physical subspace, equivalent to ordinary QC…
Effective field theories for rooted staggered fermions
Claude Bernard, Maarten Golterman, Yigal Shamir
We extend the construction of the Symanzik effective action to include rooted staggered fermions, starting from a generalization of the renormalization-group approach to rooted sta…
The Tunneling Hybrid Monte-Carlo algorithm
Maarten Golterman, Yigal Shamir
The hermitian Wilson kernel used in the construction of the domain-wall and overlap Dirac operators has exceptionally small eigenvalues that make it expensive to reach high-quality…
