title: Casimir Energy of Confining Large N Gauge Theories.
abstract: Four-dimensional asymptotically free large N gauge theories compactified on S(R)(3)×R have a weakly coupled confining regime when R is small compared to the strong scale. We compute the vacuum energy of a variety of confining large N nonsupersymmetric gauge theories in this calculable regime, where the vacuum energy can be thought of as the S(3) Casimir energy. The N=∞ renormalized vacuum energy turns out to vanish in the class of theories we have examined. This matches an implication of a recently observed temperature-reflection symmetry of such systems.
