轻子和夸克味不变量的代数结构与CP破坏

Algebraic Structure of Lepton and Quark Flavor Invariants and CP Violation

Elizabeth E. Jenkins, Aneesh V. Manohar

摘要:

本文研究了具有五维Majorana中微子质量算符的标准模型和跷跷板模型中的轻子和夸克味不变量。轻子扇区中的不变量环是高度非平凡的,基本不变量之间存在非线性关系。对两代、三代标准模型和两代跷跷板模型的不变量进行了分类,并计算了Hilbert级数。具有三代的跷跷板模型证明在计算上对于完整的解决方案太困难。给出了弱电区CP破坏角θ的不变定义。

英文摘要:

Lepton and quark flavor invariants are studied, both in the Standard Model with a dimension five Majorana neutrino mass operator, and in the seesaw model. The ring of invariants in the lepton sector is highly non-trivial, with non-linear relations among the basic invariants. The invariants are classified for the Standard Model with two and three generations, and for the seesaw model with two generations, and the Hilbert series is computed. The seesaw model with three generations proved computationally too difficult for a complete solution. We give an invariant definition of the CP-violating angle theta in the electroweak sector.
