Title Perturbative running of the topological angles
Abstract In this talk I will explore the possibility of a perturbative renormalisation of the topological angles. First I will derive the general conditions that any theory must feature in order to achieve such a renormalisation, providing also some concrete methods for its computation. I will then proceed to study a concrete toy model exhibiting these properties, that will also serve as bridge to make contact with the Strong CP problem. Finally I will mention an interesting connection to the framework of the Local Renormalisation Group, providing another, novel way of performing such a computation.
