Axion inflation is well motivated for high energy models due to the fact that it enjoys a shift symmetry. This allows it potential to be protected from large quantum loop corrections, especially at high energies. The least irrelevant coupling with axion and gauge field , which is a FF_dual, could lead some interesting phenomenology including chiral GWs at CMB scales and even smaller scales. This interaction might also leave signatures in tensor (GWs at interferometers) and density fluctuations (PBH) at scales much smaller than CMB.
