Primordial SU(2) fields, spontaneous P violation, and inflationary Gravitational waves

11.10.2019 11:30 – 12:30

Primordial SU(2) gauge fields coupled to axions can contribute to the physics of inflation. Their rich phenomenology and unique observational features, e.g., chiral primordial gravitational waves, turned this class of models to a hot topic. In this talk, I will briefly review the models in this class, which so far have been studied in the literature. Then, I will talk about the three different types of particles produced by the SU(2) gauge field, i.e., scalar, fermion, and spin-2 particles and the consequence of the spontaneous P and CP violation in this setup. I will mainly focus on the produced chiral gravitational waves, which are the generic prediction of this setup. Finally, I will finish my talk by the natural inflationary leptogenesis setting provided by this class as their yet another free opportunity!
