The interface tension in quenched QCD at the critical temperature

We present results for the confinement-deconfinement intinterface tension acd of quenched QCD. They were obtained by applying Binder's histogram method to lattices of size L2 × Lz × Lt for Lt = 2 and L = 8, 10, 12 and 14 with Lz = 30 for L = 8 and Lz = 3L otherwise. The use of a multicanonical algorithm and cylindrical geometries have turned out to be crucial for the numerical studies.
