  In this work we study a classically scale invariant extension of the Standard
Model that can explain simultaneously dark matter and the baryon asymmetry in
the universe. In our set-up we introduce a dark sector, namely a non-Abelian
SU(2) hidden sector coupled to the SM via the Higgs portal, and a singlet
sector responsible for generating Majorana masses for three right-handed
sterile neutrinos. The gauge bosons of the dark sector are mass-degenerate and
stable, and this makes them suitable as dark matter candidates. Our model also
accounts for the matter-anti-matter asymmetry. The lepton flavour asymmetry is
produced during CP-violating oscillations of the GeV-scale right-handed
neutrinos, and converted to the baryon asymmetry by the electroweak sphalerons.
All the characteristic scales in the model: the electro-weak, dark matter and
the leptogenesis/neutrino mass scales, are generated radiatively, have a common
origin and related to each other via scalar field couplings in perturbation
theory.
