Neutrino Masses and Mixings Dynamically Generated by a Light Dark Sector

摘要:

中微子可能是新暗区的预兆,因为可重整的中微子入口允许它们与隐藏的新物理相互作用。我们在这里建议利用这一事实来连接中微子质量的产生,一个光明的黑暗部门,收费下一个新的$U(1)_{\cal D}$暗规范对称性。我们引入最小暗场数,得到了一个无反常的暗对称自发破缺理论,并自动得到了反跷跷板拉格朗日量。此外,所谓的$μ$项的逆跷跷板是动态生成的,在这个框架中,技术上是自然的。作为奖励,新的亮暗规范玻色子可以为MiniBooNE异常提供一个可能的解释。

英文摘要:

Neutrinos may be the harbingers of new dark sectors, since the renormalizable neutrino portal allows for their interactions with hidden new physics. We propose here to use this fact to connect the generation of neutrino masses to a light dark sector, charged under a new $U(1)_{\cal D}$ dark gauge symmetry. We introduce the minimal number of dark fields to obtain an anomaly free theory with spontaneous breaking of the dark symmetry, and obtain automatically the inverse seesaw Lagrangian. In addition, the so-called $μ$-term of the inverse seesaw is dynamically generated and technically natural in this framework. As a bonus, the new light dark gauge boson can provide a possible explanation to the MiniBooNE anomaly.
