The Interface Tension in Quenched QCD at the Critical Temperature

Abstract

We present results for the confinement-deconfinement interface tension ${\alpha }_{cd}$ of quenched QCD. They were obtained by applying Binder's histogram method to lattices of size $L^2\times L_z\times L_t$ for $L_t=2$ and $L=8,10,12\text{mbox}and14$ with $L_z=30$ for $L=8$ and $L_z=3L$ otherwise. The use of a multicanonical algorithm and cylindrical geometries have turned out to be crucial for the numerical studies.
