A Warped Model of Dark Matter

Understand

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.
