中微子混合的水平对称性

The Horizontal Symmetry for Neutrino Mixing

C. S. Lam

摘要:

我们认为,确定水平对称性的最佳方法是从中微子混合,并继续表明,唯一的有限群能够产生所有汤川耦合的三双峰混合是$S_4$,或任何包含它的群。所使用的方法主要是群论,但是它可以通过动力学方案来实现,在动力学方案中,为了自发地破坏$S_4$而引入的希格斯期望值是唯一确定的,到一个未知的规模。

英文摘要:

We argue that the best way to determine horizontal symmetry is from neutrino mixing, and proceed to show that the only finite group capable of yielding the tri-bimaximal mixing for all Yukawa couplings is $S_4$, or any group containing it. The method used is largely group theoretical, but it can be implemented by dynamical schemes in which the Higgs expectation values introduced to break $S_4$ spontaneously are uniquely determined up to an unknown scale for each.
