论文摘要
在本文中,我们建议在带有大量相同叶子/花瓣的恒星/玫瑰图上压实一个大型额外尺寸(LED)。 5D Planck量表可以选择为$λ_p^{(5)} \ sim \ Mathcal {o}(1)$ TEV,可以提供解决规格层次结构问题的路径。叶/花瓣长度比例为$ \ MATHCAL {O}(1/λ_{ew})$,其中$λ_{ew} \ sim 100 $ GEV是弱刻度,没有传统LED模型的较大几何层次结构。 SM的4D字段位于星/玫瑰图的中央顶点的3个桥梁上。我们预测,在TEV量表以上的强烈耦合引力现象的政权下,一个微弱耦合的弱尺度Kaluza-Klein(KK)引力。此外,我们在设置中重新制定了LED机制,以产生轻度的狄拉克中微子,在该中微子中,右手中微子是批量传播的量规单程费米斯的KK模式。大量的KK-Gravitons和KK-Neutrinos仅在重力上相互作用,因此构成了一个隐藏的部门。
In this paper, we propose to compactify a single large extra dimension (LED) on a star/rose graph with a large number of identical leaves/petals. The 5D Planck scale can be chosen to be $Λ_P^{(5)} \sim \mathcal{O}(1)$ TeV which can provide a path to solve the gauge hierarchy problem. The leaf/petal length scale is of $\mathcal{O}(1/Λ_{EW})$, where $Λ_{EW} \sim 100$ GeV is the weak scale, without the large geometrical hierarchy of the traditional LED models to stabilize. The 4D fields of the SM are localized on a 3-brane at the central vertex of the star/rose graph. We predict a tower of feebly coupled weak scale Kaluza-Klein (KK) gravitons below a regime of strongly coupled gravitational phenomena above the TeV scale. Moreover, we reformulate in our setup the LED mechanism to generate light Dirac neutrinos, where the right-handed neutrinos are KK-modes of gauge singlet fermions propagating in the bulk. A large number of KK-gravitons and KK-neutrinos interact only gravitationally, and thus constitute a hidden sector.
