Description
I will first review an inflationary model that includes an axion coupled with SU(2) gauge fields. This setup can generate a chiral gravitational waves signal. I will then detail on how the parameter space of the theory supports a blue tensor spectrum and large tensor as well as scalar-tensor-tensor non-Gaussianities.
