中微子的规范理论模型与超越标准模型的新物理

Gauge Theory Model of the Neutrino and New Physics Beyond the Standard Model

Yue-Liang Wu

摘要:

中微子的Majorana特性和SO(3)三族规范对称性使我们能够构造一个中微子规范模型,结合近似整体U(1)族对称性机制,自然地理解中微子质量的微小性和近三双峰中微子混合。发现SO(3)对称性破缺的真空结构起着重要作用。混合角$θ_{13}$和CP破坏相由自发对称性破缺的真空控制,一般是非零的,并在允许的灵敏度实验可测。该模型预言了SO(3)三重态带电轻子和SO(3)三重态Majorana中微子以及SO(3)三重态希格斯玻色子的存在,其中一些粒子是轻粒子,可以在LHC和ILC对撞机上探测到.

英文摘要:

Majorana features of neutrinos and SO(3) gauge symmetry of three families enable us to construct a gauge model of neutrino for understanding naturally the observed smallness of neutrino masses and the nearly tri-bimaximal neutrino mixing when combining together with the mechanism of approximate global U(1) family symmetry. The vacuum structure of SO(3) symmetry breaking is found to play an important role. The mixing angle $θ_{13}$ and CP-violating phases governed by the vacuum of spontaneous symmetry breaking are in general non-zero and testable experimentally at the allowed sensitivity. The model predicts the existence of vector-like SO(3) triplet charged leptons and vector-like SO(3) triplet Majorana neutrinos as well as SO(3) tri-triplet Higgs bosons, some of them can be light and explored at the colliders LHC and ILC.
