Description
In this talk I will present a fundamental theory of the QCD axion: all couplings flow to zero in the infinite energy limit (realizing the totally asymptotically free scenario) and the Peccei-Quinn (PQ) scale $f_a$ is dynamically generated by quantum effects. This theory is highly predictive as the axion sector only features few free parameters: $f_a$ and the QCD gauge coupling. The PQ phase transition is strongly first order and I will discuss how to test this theory through gravitational wave detectors such as LIGO and the Einstein telescope.
