揭示兰德尔-Sundrum隐藏的山谷

Revealing Randall-Sundrum Hidden Valleys

Don Bunk, Jay Hubisz

摘要:

我们研究了Randall-Sundrum几何中的5D规范对称性,这些对称性通过小的5D规范耦合或通过消失的标准模型场的量子数而隐藏在标准模型中。5D重力的几何扭曲创建了从标准模型到隐藏扇区规范场的TeV尺度桥。我们将这些概念应用于电弱轴子模型的复兴,其中Peccei-Quinn对称性破缺的动力学发生在TeV尺度。

英文摘要:

We study 5D gauge symmetries in the Randall-Sundrum geometry that are hidden from the standard model through either small 5D gauge coupling, or through vanishing quantum numbers for the standard model fields. Geometric warping of 5D gravity creates a TeV scale bridge from the standard model to the hidden sector gauge fields. We apply these concepts to a revival of the electroweak axion model, in which the dynamics of Peccei-Quinn symmetry breaking occur at the TeV scale.
