Asymmetric matter from $$B-L$$ symmetry breaking
Keyword(s):
AbstractThe present matter content of our universe may be governed by a $$U(1)_{B-L}$$ U ( 1 ) B - L symmetry – the simplest gauge completion of the seesaw mechanism which produces small neutrino masses. The matter parity results as a residual gauge symmetry, implying dark matter stability. The Higgs field that breaks the $$B-L$$ B - L charge inflates the early universe successfully and then decays to right-handed neutrinos, which reheats the universe and generates both normal matter and dark matter manifestly.
