论文摘要
我们宇宙的目前内容可以由$ u(1)_ {b-l} $对称性(SeeSAW机制的最简单量规完成)控制,该机制产生了小的中微子质量。物质奇偶校验作为残留量规对称性,这意味着暗物质稳定性。打破$ B-l $电荷的希格斯领域成功地膨胀了早期的宇宙,然后腐烂到右撇子中微子,这使宇宙加热并显然产生正常物质和暗物质。
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.
