Matter and dark matter asymmetry from a composite Higgs model
  We propose a low scale leptogenesis scenario in the framework of composite
Higgs models supplemented with singlet heavy neutrinos. One of the neutrinos
can also be considered as a dark matter candidate whose stability is guaranteed
by a discrete $\mathbb{Z}_2 $ symmetry of the model. In the spectrum of the
strongly coupled system, bound states heavier than the pseudo Nambu-Goldstone
Higgs boson can exist. Due to the decay of these states to heavy right-handed
neutrinos, an asymmetry in the visible and dark sector is simultaneously
generated. The resulting asymmetry is transferred to the standard model leptons
which interact with visible right-handed neutrinos. We show that the
sphaleron-induced baryon asymmetry can be provided at the TeV scale for
resonant bound states. Depending on the coupling strength of dark neutrino
interaction, a viable range of the dark matter mass is allowed in the model.
Furthermore, taking into account the effective interactions of dark matter, we
discuss low-energy processes and experiments.
