Dark fermions and spontaneous CP violation in SU(2)-axion inflation
Abstract Remarkably, if CP was spontaneously broken in the physics of inflation, fermions would notice and remember it. Based on that, we present a new (non-thermal) mechanism for generating self-interacting dark Dirac fermions prior to the Hot Big Bang. The non-Abelian gauge fields and axions are w...
