Asymmetric dark matter, inflation, and leptogenesis from B-L symmetry breaking

Phung Van Dong, D. T. Huong, Daniel A. Camargo and Farinaldo S. Queiroz, José W. F. Valle

We propose a unified setup for dark matter, inflation, and baryon asymmetry generation through the neutrino mass seesaw mechanism. Our scenario emerges naturally from an extended gauge group containing B-L as a noncommutative symmetry, broken by a singlet scalar that also drives inflation. Its decays reheat the universe, producing the lightest right-handed neutrino. Automatic matter parity conservation leads to the stability of an asymmetric dark matter candidate, directly linked to the matter-antimatter asymmetry in the Universe.
