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…
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…
QCD thermodynamics with 2+1 flavors at nonzero chemical potential
C. Bernard, C. DeTar, Steven Gottlieb +5
We present results for the QCD equation of state, quark densities and susceptibilities at nonzero chemical potential, using 2+1 flavor asqtad ensembles with . The ensembles…
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…
Scalar Meson Spectroscopy with Lattice Staggered Fermions
Claude Bernard, Carleton DeTar, Ziwen Fu +1
With sufficiently light up and down quarks the isovector () and isosinglet () scalar meson propagators are dominated at large distance by two-meson states. In the stagger…
