Thermodynamics of Four-Flavour QCD with Improved Staggered Fermions
J. Engels, R. Joswig, F. Karsch +3
We have calculated the pressure and energy density in four-flavour QCD using improved fermion and gauge actions. We observe a strong reduction of finite cut-off effects in the high…
A Study of Finite Temperature Gauge Theory in (2+1) Dimensions
J. Engels, F. Karsch, E. Laermann +4
We determine the critical couplings and the critical exponents of the finite temperature transition in SU(2) and SU(3) pure gauge theory in (2+1) dimensions. We also measure Wilson…
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…
Two Flavour QCD Phase Transition
G. Boyd, F. Karsch, E. Laermann +1
Results on the phase transition in QCD with two flavours of light staggered fermions from an ongoing simulation are presented. We find the restoration of the chiral SU(2) x SU(2) s…
Thermodynamics of SU(3) Lattice Gauge Theory
G. Boyd, J. Engels, F. Karsch +4
The pressure and the energy density of the gauge theory are calculated on lattices with temporal extent , 6 and 8 and spatial extent and 32. The results ar…
