SU(5)SUSY模型中的风味Delta(54)

Flavor Delta(54) in SU(5) SUSY Model

J. A. Escobar

摘要:

我们利用SU(3)f的有限非交换子群Δ(54)设计了一个超对称SU(5)大统一模型。我们引入了重右手中微子,它们变换为我们所选族群的三维表示。该模型成功地再现了质量等级质量结构的标准模型,和CKM混合矩阵。然后,它提供了轻中微子的预测与正常的层次和质量,使mν,1 \approx 5 \times 10-3 eV,mν,2 \approx 1 \times 10-2 eV,和mν,3 \approx 5 \times 10-2 eV。我们还提供了重中微子质量的预测,以及在实验范围内(例如,反应堆角度为-7.31o)对三-双极大矩阵的修正。一个简单的修改,我们的模型介绍了在年底,并显示也产生的预测,以及落在这些限制。

英文摘要:

We design a supersymmetric SU (5) GUT model using Δ(54), a finite non-abelian subgroup of SU (3)f . Heavy right handed neutrinos are introduced which transform as three-dimensional repre-sentation of our chosen family group. The model successfully reproduces the mass hierarchical mass structures of the Standard Model, and the CKM mixing matrix. It then provides predictions for the light neutrino with a normal hierarchy and masses such that mν,1 \approx 5\times10-3 eV, mν, 2 \approx 1\times 10-2 eV, and mν,3 \approx 5 \times 10-2 eV. We also provide predictions for masses of the heavy neutrinos, and correc- tions to the tri-bimaximal matrix that fit within experimental limits, e.g. a reactor angle of -7.31o. A simple modification to our model is introduced at the end and is shown to also produce predictions that fall well within those limits.
