论文摘要
我们将$ su(3)_C \ times su(2)_l \ times u(1)_y $ $标准模型通过$ u(1)_ {y''} $ gauge Symmetry。引入了三个右撇子中微子以取消量规异常。一个Higgs Singlet负责自发打破$ u(1)_ {y'} $对称性,而标准模型higgs doublet则不带任何$ u(1)_ {y''} $费用。廉价的夸克,上的夸克,带电的钩子和中性中微子通过由Higgs Doublet和Singlet构建的四种类型的Dimension-5运算符获得了狄拉克质量。这种有效的理论是在三种可重新分解的背景下实现的,具有沉重的费米昂单线,标量双线和费米昂双峰。产生中微子肿块的沉重的费米昂单曲线和双重组也容纳了成功的Dirac瘦素发生,以解释宇宙中的Baryon不对称性。
We extend the $SU(3)_c \times SU(2)_L \times U(1)_Y$ standard model by a $U(1)_{Y'}$ gauge symmetry. Three right-handed neutrinos are introduced to cancel the gauge anomaly. One Higgs singlet is responsible for spontaneously breaking the $U(1)_{Y'}$ symmetry while the standard model Higgs doublet does not carry any $U(1)_{Y'}$ charges. The down-type quarks, up-type quarks, charged leptons and neutral neutrinos obtain their Dirac masses through four types of dimension-5 operators constructed by the fermion doublets and singlets with the Higgs doublet and singlet. This effective theory is realized in three renormalizable contexts with heavy fermion singlets, scalar doublets and fermion doublets. The heavy fermion singlets and doublets for generating the neutrino masses also accommodate a successful Dirac leptogenesis to explain the baryon asymmetry in the universe.
