含三个Higgs族的轨道模型中的轻子质量和混合

Lepton masses and mixings in orbifold models with three Higgs families

N. Escudero, C. Munoz, A. M Teixeira

摘要:

我们分析了具有两条Wilson线的杂化Z(3)轨道的唯象可行性,它自然地预言了三个超对称物质家族和Higgs场。鉴于这些模型可以适应现实的情况下,夸克部门避免潜在的危险的味道改变中性电流,我们现在解决轻子部门,发现可行的orbifold配置原则上可以获得。特别是,它可以容纳带电轻子质量的现有数据,同时避免与轻子味道违反衰变的冲突。关于中微子质量和混合的产生,我们发现Z(3)轨道提供了几种有趣的可能性。

英文摘要:

We analyse the phenomenological viability of heterotic Z(3) orbifolds with two Wilson lines, which naturally predict three supersymmetric families of matter and Higgs fields. Given that these models can accommodate realistic scenarios for the quark sector avoiding potentially dangerous flavour-changing neutral currents, we now address the leptonic sector, finding that viable orbifold configurations can in principle be obtained. In particular,it is possible to accomodate present data on charged lepton masses, while avoiding conflict with lepton flavour-violating decays. Concerning the generation of neutrino masses and mixings, we find that Z(3) orbifolds offer several interesting possibilities.
