Abstract: (APS)
We present Monte Carlo evidence of a first-order phase transition in four-dimensional SO(3) lattice gauge theory. This result stands in sharp contrast to the known single-phase structure of the corresponding SU(2) theory, and suggests that the Z2 center degrees of freedom may be important to the thermodynamics of the SU(2) gauge system.
