Abstract
We calculate the high temperature partition functions for SU(N c ) or U(N c ) gauge theories in the deconfined phase on S 1 × S 3, with scalars, vectors, and/or fermions in an arbitrary representation, at zero ’t Hooft coupling and large N c, using analytical methods. We compare these with numerical results which are also valid in the low temperature limit and show that the Bekenstein entropy bound resulting from the partition functions for theories with any amount of massless scalar, fermionic, and/or vector matter is always satisfied when the zero-point contribution is included, while the theory is sufficiently far from a phase transition. We further consider the effect of adding massive scalar or fermionic matter and show that the Bekenstein bound is satisfied when the Casimir energy is regularized under the constraint that it vanishes in the large mass limit. These calculations can be generalized straightforwardly for the case of a different number of spatial dimensions.
