Subject: The Warped Dark Sector

I present a dark sector scenario based on a slice of 5d AdS space. Such a construction, also motivated as the AdS dual of a composite dark sector, naturally leads to models in which parts of the dark sector vanish at high 4d momentum. This AdS "opacity" arises from the dressing of propagators by bulk interactions. Exotic dark sector signatures are possible from laboratory to cosmological scales, including long-range forces with non-integer behaviour, non-standard momentum losses, and periodic signals at colliders.
