中微子混合和私人希格斯粒子

Neutrino Mixing and the Private Higgs

Rafael A. Porto, A. Zee

摘要:

我们通过为每个轻子家族引入一个私人希格斯场,扩展了私人希格斯场的情形来考虑带电轻子和中微子的质量。我们分析了一个模型,其中中微子马约拉纳质量辐射诱导。与以前的模型相反,中微子质量尺度~ 10^{-2} eV是自然获得的,没有过多的微调。该模型需要引入SU(2)单重标量场,两个带电场和一个中性场。我们讨论了一种可能的实现给出一个正常的中微子质量等级。我们的模型拟合数据并预测非零的V_{e3}。

英文摘要:

We extend the Private Higgs scenario to account for charged lepton and neutrino masses by introducing a private Higgs field for each lepton family. We analyze a model in which neutrino Majorana masses are radiatively induced. Contrary to previous models the neutrino mass scale ~ 10^{-2} eV is naturally obtained without excessive fine tunings. The model requires the introduction of SU(2) singlet scalar fields, two charged and one neutral. We discuss a possible realization giving a normal neutrino mass hierarchy. Our model fits data and predicts a non-zero V_{e3}.
