Abstract / Bemerkung
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-tau = 3 and 4 and spatial extent N-sigma/N-tau = 4, 6 and 8. In comparison to the standard Wilson action we do find a drastic reduction of cut-off effects already with tree level improved actions. On lattices with temporal extent N-tau = 4 results for the surface tension and latent heat obtained with a tree level improved action agree well with those obtained with a tadpole improved action. A comparison with N-tau = 3 calculations, however, shows that results obtained with tadpole action remain unaffected by cut-off effects even on this coarse lattice, while the tree level action becomes sensitive to the cut-off. For the surface tension and latent heat we find sigma(1)/T-c(3) = 0.0155 (16) and Delta epsilon/T-c(4) = 1.40 (9), respectively.
