From minimal to general: the structure of axion solutions to the strong CP problem
Speaker: Mario Fernandez Navarro (University of Zurich) The QCD axion provides a compelling solution to the strong CP problem. In this talk I will discuss a minimal origin for the otherwise unspecified Peccei-Quinn symmetry of the QCD axion based on an extra-dimensional gauge theory, which nevertheless retains much of the simplicity of traditional KSVZ/DFSZ anomaly …
