Abstract:
If fermion condensation is a main source of electroweak symmetry breaking, an ultra-heavy Higgs doublet can yield naturally small Dirac neutrino masses. We show that such a scenario can lead to a new leptogenesis mechanism based on the decays of the ultra-heavy Higgs.
We outline how our scenario can also naturally lead to composite asymmetric dark matter. Some potential signals of this scenario are discussed.
