Understand

A mechanism for leptogenesis at the electroweak scale was investigated in a model of dark energy and dark matter proposed by one of us (PQH).

This model involves an asymptotically free gauge group SU(2)Z and an axion-like particle with an SU(2)Z-instanton-induced potential which yields a scenario for the dark energy.
Furthermore, the extended particle content of this SU(2)Z model contains a possible candidate for the cold dark matter, namely, the SU(2)Z "shadow" fermion, which couples with the Standard Model lepton through a scalar "messenger field" carrying both SU(2)Z and electroweak quantum numbers.
Since these shadow fermions are in a real representation of SU(2)Z, lepton number can be violated in the Yukawa sector and a lepton number asymmetry can be generated in the SU(2)Z particle's decay which is also CP-violating and "out-of-equilibrium".
