Staggered Fermion Actions with Improved Rotational Invariance
B. Beinlich, A. Bicker, F. Karsch +2
We introduce a class of improved actions for staggered fermions which to O(p^4) and O(p^6), respectively, lead to rotationally invariant propagators. We discuss the resulting reduc…
The string tension in SU(N) gauge theory from a careful analysis of smearing parameters
C. Legeland, B. Beinlich, M. Lütgemeier +2
We report a method to select optimal smearing parameters before production runs and discuss the advantages of this selection for the determination of the string tension.
On QCD Thermodynamics with Improved Actions
Frithjof Karsch
We discuss recent advances in the calculation of thermodynamic observables using improved actions. In particular, we discuss the calculation of the equation of state of the SU(3) g…
String Tension and Thermodynamics with Tree Level and Tadpole Improved Actions
B. Beinlich, F. Karsch, E. Laermann +1
We calculate the string tension, deconfinement transition temperature and bulk thermodynamic quantities of the SU(3) gauge theory using tree level and tadpole improved actions. Fin…
SU(3) Latent Heat and Surface Tension from Tree Level and Tadpole Improved Actions
B. Beinlich, F. Karsch, A. Peikert
We analyze the latent heat and surface tension at the SU(3) deconfinement phase transition with tree level and tadpole improved Symanzik actions on lattices with temporal extent $N…
QCD Thermodynamics with Improved Actions
F. Karsch, B. Beinlich, J. Engels +4
The thermodynamics of the SU(3) gauge theory has been analyzed with tree level and tadpole improved Symanzik actions. A comparison with the continuum extrapolated results for the s…
