Non-Local Observables in the A-Model

We compute correlators of non-local observables in a large class of A-twisted massive Landau-Ginzburg and gauged linear sigma models by localization to the discrete vacua. As an application, we present two topological field theories with identical chiral rings and correlators of local observables, which nevertheless differ in the correlators of non-local observables.
