Evidence for a critical behavior in 4D pure compact QED

Jersák, Jiri, Lang, C B, Neuhaus, T

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.
