Description
I will first quickly review the mechanism for primordial gravitational wave (GW) generation in axion-inflation models coupled with a gauge sector via a Chern-Simons term. I will then specialise to the case of an SU(2) sector in a setup where the inflaton is non-minimally coupled to gravity and detail on the gravitational wave spectrum at small scales, those of interest for GW interferometers.
