具有$A_4$对称性和重轻子的3-3-1模型中的中微子混合矩阵

Neutrino mixing matrix in the 3-3-1 model with heavy leptons and $A_4$ symmetry

Furong Yin

摘要:

我们研究了基于局域规范群$SU(3)_c\otimes SU(3)_L\otimes U(1)_X$的不含奇异电荷粒子的模型中的轻子扇区。在模型中引入了跷跷板机制和离散的$A_4$对称性,以理解中微子特别轻的原因和观察到的中微子混合模式。该模型提供了一种求取首阶三二重极大混合矩阵的方法。在修正的混合矩阵中存在非零混合角$V_{e3}$。

英文摘要:

We study the lepton sector in the model based on the local gauge group $SU(3)_c\otimes SU(3)_L\otimes U(1)_X$ which do not contain particles with exotic electric charges. The seesaw mechanism and discrete $A_4$ symmetry are introduced into the model to understand why neutrinos are especially light and the observed pattern of neutrino mixing. The model provides a method for obtaining the tri-bimaximal mixing matrix in the leading order. A non-zero mixing angle $V_{e3}$ presents in the modified mixing matrix.
