多Higgs模型中的TeV-scale跷跷板

TeV-scale seesaw from a multi-Higgs model

Naoyuki Haba, Masaki Hirotsu

摘要:

我们提出了一个新的简单模型,通过TeV尺度的跷跷板机制产生微小的中微子质量,而不需要微小的汤川耦合。该模型是标准模型的简单扩展,通过引入额外的一个希格斯单线态和一个具有微小真空期望值的希格斯双线态。实验约束,电弱精度数据和没有大的味道改变中性电流,是满意的,因为额外的双重只有一个汤川相互作用的轻子双重和右手中微子,和他们的质量是沉重的TeV规模的顺序。由于活跃的轻中微子是马约拉纳粒子,这个模型预言了一个无中微子的双β衰变。

英文摘要:

We suggest new simple model of generating tiny neutrino masses through a TeV-scale seesaw mechanism without requiring tiny Yukawa couplings. This model is a simple extension of the standard model by introducing extra one Higgs singlet, and one Higgs doublet with a tiny vacuum expectation value. Experimental constraints, electroweak precision data and no large flavor changing neutral currents, are satisfied since the extra doublet only has a Yukawa interaction with lepton doublets and right-handed neutrinos, and their masses are heavy of order a TeV-scale. Since active light neutrinos are Majorana particles, this model predicts a neutrinoless double beta decay.
