来自一个隐蔽世界的中微子质量及其唯象意义

Neutrino mass from a hidden world and its phenomenological implications

Seong Chan Park, Kai Wang, Tsutomu T. Yanagida

摘要:

我们提出了一个额外维中中微子质量产生的模型。在空间上与标准模型膜分离的遥远膜上允许大的轻子数破坏,由于信使场在5D体中的指数抑制,自然会产生小的中微子质量。该模型可以容纳与单重态中微子(n_R)的大Yukawa耦合,这可能会改变标准的Higgs搜索,同时可以容纳在电弱尺度下可见的轻子数破坏,这导致了在CERN大型强子对撞机上非常有趣的现象。

英文摘要:

We propose a model of neutrino mass generation in extra dimension. Allowing a large lepton number violation on a distant brane spatially separated from the standard model brane, a small neutrino mass is naturally generated due to an exponential suppression of the messenger field in the 5D bulk. The model accommodates a large Yukawa coupling with the singlet neutrino (n_R) which may change the standard Higgs search and can simultaneously accommodate visible lepton number violation at the electroweak scale, which leads to very interesting phenomenology at the CERN Large Hadron Collider.
