Gravity-mediated (or Composite) Dark Matter

Understand

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.
