The surface tension at the deconfinement transition of SU(3) is determined with a parametrized version of the fixed point action of a renormalization group transformation on lattices with temporal extent Nt=3 and 4 and spatial extent Ns/Nt=3 and 4. A considerable cut-off dependence can be seen in comparison with earlier determinations from tree level Symanzik and tadpole improved actions.

Abstract
The surface tension at the deconfinement transition of SU(3) is determined with a parametrized version of the fixed point action of a renormalization group transformation on lattices with temporal extent Nt=3 and 4 and spatial extent Ns/Nt=3 and 4. A considerable cut-off dependence can be seen in comparison with earlier determinations from tree level Symanzik and tadpole improved actions.File in questo prodotto:
