引力介导的(或复合的)暗物质

Gravity-mediated (or Composite) Dark Matter

Hyun Min Lee, Myeonghun Park, Veronica Sanz

摘要:

暗物质可能有一个电弱的起源,但与可见部分的沟通完全通过引力相互作用。在一个解决层次问题的设置,我们提出了一个新的暗物质的情况下,引力介质,所产生的额外维度的紧致化,负责暗物质的相互作用和它的遗迹在宇宙中的丰度。我们写了一个明确的例子,这种机制在扭曲的额外的维度,并制定出其约束。我们还开发了一个双图片的模型,基于一个四维的情况下,部分复合。我们表明,引力介导的暗物质是相当于一种机制,产生可行的暗物质的情况下,在强耦合,近共形理论,如在复合希格斯模型。

英文摘要:

Dark matter could have an electroweak origin, yet communicate with the visible sector exclusively through gravitational interactions. In a set-up addressing the hierarchy problem, we propose a new dark matter scenario where gravitational mediators, arising from the compactification of extra-dimensions, are responsible for dark matter interactions and its relic abundance in the Universe. We write an explicit example of this mechanism in warped extra-dimensions and work out its constraints. We also develop a dual picture of the model, based on a four-dimensional scenario with partial compositeness. We show that Gravity-mediated Dark Matter is equivalent to a mechanism of generating viable dark matter scenarios in a strongly-coupled, near-conformal theory, such as in composite Higgs models.
