Asymmetric matter from B-L symmetry breaking

The present matter content of our universe may be governed by a 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...

Zusammenfassung:	The present matter content of our universe may be governed by a 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 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.
