Interface Tension in Quenched QCD

Abstract

We calculate the tension $\sigma$ of the interface between the confined and deconfined phases by the histogram method in SU(3) lattice gauge theory for temporal extents of 4 and 6 using the recent high-statistics data by QCDPAX collaboration. The results are $\sigma /T_c^3=0.0292(22)$ and 0.0218(33) for $N_t=4$ and 6, respectively. The ratio $\sigma /T_c^3$ shows a scaling violation similar to that already observed for the latent heat $\text{latent}$. However, we find that the physically interesting dimensionless combinations $({\sigma }^3/{\text{latent}}^{2}T{)}^{1/2}$ and $\sigma T/\text{latent}$ scale within the statistical errors.
