Abstract
We consider a chiral gauge theory from which light composite Dirac neutrinos dynamically emerge, augmented by a QCD axion to solve the strong problem. We show that an interplay between the composite sector and the axion can also simultaneously lead to successful baryogenesis and generate a correct dark matter abundance via “cogenesis” without contradicting present constraints. We predict and in the range , which can be firmly tested by upcoming CMB experiments and axion searches.
