String tension and thermodynamics with tree level and tadpole improved actions

Beinlich B, Karsch F, Laermann E, Peikert A. String tension and thermodynamics with tree level and tadpole improved actions. In: Nuclear Physics B - Proceedings Supplements. NUCLEAR PHYSICS B-PROCEEDINGS SUPPLEMENTS. Vol 63. ELSEVIER SCIENCE BV; 1998: 922-924.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. Finite temperature calculations have been performed on lattices with temporal extent N-t = 3 and 4. We also compare the cut-off effects in the high temperature limit for different improved actions
