On the large N limit of SU(N) lattice gauge theories in five dimensions

Understand

We develop the necessary tools for computing fluctuations around a mean-field background in the context of SU(N) lattice gauge theories in five dimensions.

• In particular, expressions for the scalar observable and the Wilson Loop are given.
• As an application, using these observables we compute a certain quantity k5 that can be viewed as Coulomb's constant in five dimensions.
• We show that this quantity becomes independent of N in the large N limit.
