具有序贯U(1)规范对称性的分级夸克和轻子质量

Hierarchical Quark and Lepton Masses with Sequential U(1) Gauge Symmetry

Ernest Ma

摘要:

取代右手中微子单线态,标准模型被扩展到包括轻子三线态$(Σ^+, Σ^0, Σ^-)$。每个夸克和轻子族现在都可以在一个无反常的$U(1)_X$规范对称性下变换,这个对称性已经知道很多年了。一个新的顺序应用,仅使用一个标准模型的希格斯双重态,连同两个$U(1)_X$希格斯单线态。由此产生的结构具有分级的夸克和轻子质量,以及一个可行的跷跷板中微子质量矩阵。

英文摘要:

Instead of right-handed neutrino singlets, the standard model is extended to include lepton triplets $(Σ^+, Σ^0, Σ^-)$. Each quark and lepton family may now transform under an anomaly-free $U(1)_X$ gauge symmetry, known already for many years. A new sequential application is presented, using just the one Higgs doublet of the standard model, together with two $U(1)_X$ Higgs singlets. The resulting structure has hierarchical quark and lepton masses, as well as a viable seesaw neutrino mass matrix.
