一个扭曲的暗物质模型

A Warped Model of Dark Matter

Tony Gherghetta, Benedict von Harling

摘要:

我们提出了一个扭曲的额外维度中的暗物质模型,其中暗扇区质量尺度是自然产生的,没有超对称性。负责暗物质主要湮灭为轻子的暗力是由暗光子介导的,暗光子通过介子耦合自然获得GeV范围内的质量。除了解决规范层次问题外,我们的模型还预测了TeV范围内的暗物质,包括伪狄拉克态之间自然存在的微小质量分裂。通过AdS/CFT对应,暗光子和暗物质都被解释为强耦合对偶4d理论的复合态.因此,在我们的模型中,暗区出现在TeV尺度上,来自一种新的强力的动力学。

英文摘要:

We present a model of dark matter in a warped extra dimension in which the dark sector mass scales are naturally generated without supersymmetry. The dark force, responsible for dark matter annihilating predominantly into leptons, is mediated by dark photons that naturally obtain a mass in the GeV range via a dilaton coupling. As well as solving the gauge hierarchy problem, our model predicts dark matter in the TeV range, including naturally tiny mass splittings between pseudo-Dirac states. By the AdS/CFT correspondence both the dark photon and dark matter are interpreted as composite states of the strongly-coupled dual 4d theory. Thus, in our model the dark sector emerges at the TeV scale from the dynamics of a new strong force.
