Perturbation theory for O(3) topological charge correlators
Miguel Aguado, Erhard Seiler
To check the consistency of positivity requirements for the two-point correlation function of the topological charge density, which were identified in a previous paper, we are comp…

The clash of positivities in topological density correlators
Miguel Aguado, Erhard Seiler
We discuss the apparent conflict between reflection positivity and positivity of the topological susceptibility in two-dimensional nonlinear sigma models and in four-dimensional ga…
