论文摘要
我们提供了一个最小的替代量级u（1）$ _ {\ rm b-l} $模型，其中三个右撇子中微子的费用为（5，-4，-4），仅引入了一个带电荷1的B-L Higgs字段。如果引入了两个右手中微子的$ Z_2 $对称性，则可以获得一致的主动中微子质量和混合。它预测了两个沉重的退化右撇子中微子，它们可能会意识到诱发诱导的情况，一个相对较轻的无菌中微子，这是一个很好的候选暗物质。
We provide a minimal alternative gauged U(1)$_{\rm B-L}$ model in which three right-handed neutrinos with charges of (5,-4,-4) and only one B-L Higgs field with charge 1 are introduced. Consistent active neutrino masses and mixings can be obtained if the $Z_2$ symmetry on two of the right-handed neutrinos is introduced. It predicts two heavy degenerate right-handed neutrinos, which may realize resonant leptogenesis scenario, and one relatively light sterile neutrino, which is a good dark matter candidate.
