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…
Dimensional Reduction and the Yang-Mills Vacuum State in 2+1 Dimensions
J. Greensite, S. Olejnik
We propose an approximation to the ground state of Yang-Mills theory, quantized in temporal gauge and 2+1 dimensions, which satisfies the Yang-Mills Schrodinger equation in both th…
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…
