Evidence for a Critical Behavior in $4D$ Pure Compact QED

Abstract

We present evidence about a critical behavior of $4D$ compact QED (CQED) pure gauge theory. Regularizing the theory on lattices homotopic to a sphere, we present evidence for a critical, i.e. second order like behavior at the deconfinement phase transition for certain values of the coupling parameter $\gamma$.Comment: 3 pages, 3 figures, POSTSCRIPT file (127KB uuencoded
