基于S4的SUSY SU(5)模型中的双峰混合和大theta13

Bimaximal mixing and large theta13 in a SUSY SU(5) model based on S4

Davide Meloni

摘要:

最近对世界中微子数据的分析,包括T2K和MINOS的结果,指向一个统计上显著的偏离0的θ 13。本文提出了一个基于离散S4群的SUSY SU(5)模型,它预言了一个大的θ 13阶的θ 13,θ 13是Cabibbo角。中微子区的其他混合角都与目前的实验数据相一致。在夸克扇区,CKM混合矩阵的条目,以及在上和下夸克扇区的质量等级是很好地再现,只需要一个小的增强,以再现DracdaC。

英文摘要:

The recent analyses of the world neutrino data, including the T2K and MINOS results, point toward a statistically significant deviation of theta13 from zero. In this paper we present a SUSY SU(5) model based on the discrete S4 group which predicts a large theta13 of order lambdaC, lambdaC being the Cabibbo angle. The other mixing angles in the neutrino sector are all compatible with current experimental data. In the quark sector, the entries of the CKM mixing matrix as well as the mass hierarchies in both up and down quark sectors are well reproduced and only a small enhancement is needed to reproduce lambdaC.
