Why (staggered fermions)^{1/4} fail at finite density
Benjamin Svetitsky, Yigal Shamir, Maarten Golterman
Because the staggered fermion determinant is complex at nonzero mu, taking its fourth root leads to phase ambiguities. These unphysical effects cause the measure to become disconti…
Color Screening, Casimir Scaling, and Domain Structure in G(2) and SU(N) Gauge Theories
J. Greensite, K. Langfeld, S. Olejnik +2
We argue that screening of higher-representation color charges by gluons implies a domain structure in the vacuum state of non-abelian gauge theories, with the color magnetic flux…
Peculiarities in the Spectrum of the Adjoint Scalar Kinetic Operator in Yang-Mills Theory
J. Greensite, A. V. Kovalenko, S. Olejnik +3
We study the spectrum of low-lying eigenmodes of the kinetic operator for scalar particles, in the color adjoint representation of Yang-Mills theory. The kinetic operator is the co…
Observations on staggered fermions at non-zero lattice spacing
Claude Bernard, Maarten Golterman, Yigal Shamir
We show that the use of the fourth-root trick in lattice QCD with staggered fermions corresponds to a non-local theory at non-zero lattice spacing, but argue that the non-local beh…
Vortices, Symmetry Breaking, and Temporary Confinement in SU(2) Gauge-Higgs Theory
J. Greensite, S. Olejnik
We further investigate center vortex percolation and Coulomb gauge remnant symmetry breaking in the SU(2) gauge-Higgs model. We show that string breaking is visible in Polyakov lin…
Quenched penguins and the Delta I=1/2 rule
M. Golterman, E. Pallante
The transformation properties of strong penguin operators under the action of the flavor group change when they are considered as operators in (partially) quenched QCD instead of t…
