Abstract

We consider lattice gauge theories on Z4 with Wilson action and structure group Zn. We compute the expectation of Wilson loop observables to leading order in the weak coupling regime, extending and refining a recent result of Chatterjee. Our proofs use neither duality relations nor cluster expansion techniques.

Nous considérons les théories de jauge sur réseau sur Z4 avec l’action de Wilson et le groupe de structure Zn. Nous calculons l’espérance des observables de la boucle de Wilson à l’ordre principal dans le régime de couplage faible, prolongeant et affinant un résultat récent de Chatterjee. Nos preuves n’utilisent ni relations de dualité ni techniques d’expansion d’amas.
