Donaldson-Witten invariants and pure 4D QCD with order and disorder 't Hooft-like operators

Cattaneo, A S; Cotta-Ramusino, P; Gamba, A; Martellini, M (1995). Donaldson-Witten invariants and pure 4D QCD with order and disorder 't Hooft-like operators. Physics Letters B, 355(1-2):245-254.

Abstract

In this paper we study the first-order formalism of pure four-dimensional SU(2) Yang-Mills theory with theta-term. We describe the Green functions associated to the electric and magnetic flux operators à la 't Hooft, by means of gauge-invariant non-local operators. These Green functions are related to Witten's invariants of four-manifolds.
