族统一中的自然费米子质量等级和混合

Natural fermion mass hierarchy and mixings in family unification

James B. Dent, Robert Feger, Thomas W. Kephart, S. Nandi

摘要:

我们提出了一个SU(9)模型的家庭统一与三个轻手征家庭,和一个自然的层次带电费米子质量和混合。在我们的模型中,单重态右手中微子的存在是令人信服的,它们的质量比大统一理论的尺度小两个数量级,这是通过跷跷板机制来理解轻中微子质量所必需的。

英文摘要:

We present an SU(9) model of family unification with three light chiral families, and a natural hierarchy of charged fermion masses and mixings. The existence of singlet right handed neutrions with masses about two orders of magnitude smaller than the GUT scale, as needed to understand the light neutrinos masses via the see-saw mechanism, is compelling in our model.
