Mixed Action Effective Field Theory: an Addendum
Jiunn-Wei Chen, Maarten Golterman, Donal O'Connell +1
We correct a mistake in the literature regarding the additive lattice spacing corrections to the mixed valence-sea meson mass and discuss the consequences for mixed action extrapol…
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…
On the Ambiguity of Spontaneously Broken Gauge Symmetry
W. Caudy, J. Greensite
Local gauge symmetries cannot break spontaneously, according to Elitzur's theorem, but this leaves open the possibility of breaking some global subgroup of the local gauge symmetry…
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…
