具有T'族对称性的RS中夸克和轻子的可行味模型

A Viable Flavor Model for Quarks and Leptons in RS with T' Family Symmetry

Mu-Chun Chen, K. T. Mahanthappa, Felix Yu

摘要:

我们提出了一个基于双四面体群T '的具有体族对称性的Randall-Sundrum模型,它产生了三双极大中微子混合模式和一个现实的CKM矩阵。T'对称性禁止了夸克和轻子扇区中的三级变味中性流,因为不同世代的费米子统一成T'的多重态。这导致低的第一KK质量尺度,因此该模型可以在对撞机实验中进行测试。

英文摘要:

We propose a Randall-Sundrum model with a bulk family symmetry based on the double tetrahedral group, T', which generates the tri-bimaximal neutrino mixing pattern and a realistic CKM matrix. The T' symmetry forbids tree-level flavor-changing-neutral-currents in both the quark and lepton sectors, as different generations of fermions are unified into multiplets of T'. This results in a low first KK mass scale and thus the model can be tested at collider experiments.
