走向一个完整的$ Δ(27)\times SO(10) $ SUSY GUT

Towards a complete $ Δ(27)\times SO(10) $ SUSY GUT

F. Björkeroth

摘要:

我讨论了一个重正化模型的基础上$Δ(27)$家庭对称性与$SO(10)$大统一理论(GUT)与自发几何$CP$破坏。对称性在大统一理论的破缺尺度附近被破缺,产生最小超对称标准模型。低尺度汤川结构是由物质与$ Δ(27) $反三重态$ \barϕ $的耦合决定的,其真空期望值通过超势在CSD 3方向上对齐。轻物理的马约拉纳中微子质量出现在$SO(10)$内的跷跷板机制。该模型预测了一个正常的中微子质量等级的最佳拟合最轻的中微子质量$ m_1 \sim 0.3 $ meV,$CP$违反振荡相位$δ^l\approx 280^{\circ}$和其余的中微子参数都在$1 σ$的最佳拟合实验值。

英文摘要:

I discuss a renormalisable model based on $Δ(27)$ family symmetry with an $SO(10)$ grand unified theory (GUT) with spontaneous geometrical $CP$ violation. The symmetries are broken close to the GUT breaking scale, yielding the minimal supersymmetric standard model. Low-scale Yukawa structure is dictated by the coupling of matter to $ Δ(27) $ antitriplets $ \barϕ $ whose vacuum expectation values are aligned in the CSD3 directions by the superpotential. Light physical Majorana neutrinos masses emerge from the seesaw mechanism within $SO(10)$. The model predicts a normal neutrino mass hierarchy with the best-fit lightest neutrino mass $ m_1 \sim 0.3 $ meV, $CP$-violating oscillation phase $δ^l\approx 280^{\circ}$ and the remaining neutrino parameters all within $1 σ$ of their best-fit experimental values.
