轻不育中微子的左右对称理论

Left-Right Symmetric Theory with Light Sterile Neutrinos

Michael Duerr, Pavel Fileviez Perez, Manfred Lindner

摘要:

提出了宇称、重子和轻子数自发破缺的一个简单理论框架。在这种情况下,重子和轻子数是独立的局部规范对称性,而宇称是利用左右对称性定义的。我们表明,在极小模型的新leptoquark领域需要定义一个无异常的理论也产生中微子质量通过III型跷跷板机制。讨论了中微子的光谱和一些唯象问题。这个理论预言可能存在两个轻的惰性中微子。

英文摘要:

A simple theoretical framework for the spontaneous breaking of parity, baryon and lepton numbers is proposed. In this context, the baryon and lepton numbers are independent local gauge symmetries, while parity is defined making use of the left-right symmetry. We show that in the minimal model the new leptoquark fields needed to define an anomaly-free theory also generate neutrino masses through the type III seesaw mechanism. The spectrum of neutrinos and some phenomenological aspects are discussed. This theory predicts the possible existence of two light sterile neutrinos.
