DESCRIPTION:The QCD axion provides a compelling solution to the strong CP 
 problem. In this talk I will discuss a minimal origin for the otherwise un
 specified Peccei-Quinn symmetry of the QCD axion based on an extra-dimensi
 onal gauge theory\, which nevertheless retains much of the simplicity and 
 mass-coupling prediction of minimal QCD axion models. I will then consider
  more general scenarios involving additional PQ-breaking sources compatibl
 e with the strong CP solution\, and/or multiple axion states originating f
 rom extra PQ symmetries. I will show that the photon-coupling phenomenolog
 y is qualitatively controlled by two structural properties: whether a line
 ar combination of PQ symmetries broken only by QCD exists\, and whether th
 e anomaly coefficients are universal. This leads to a general sum rule gov
 erning the (multi-)axion system\, helping to connect a potential experimen
 tal signature with the underlying axion potential and its UV completion. F
 inally\, I will highlight the flavour deconstruction of QCD as an illustra
 tive UV realisation of many qualitative multi-axion regimes\n\nhttps://ind
