反德西特空间中的五维膜世界结构自然会导致暗扇区的场景，其中部分暗扇区在高四维动量或温度下消失。用修正引力的语言来说，这种特征意味着一种隐藏光标量的新机制，以及紫外线完成变色龙般有效理论的可能性。在暗物质现象学的语言中，介质扇区的高能量行为改变了暗物质观测的互补性。从实验室到宇宙学尺度，存在着大量的签名，包括奇异的签名，包括具有非整数行为的长程力，对撞机上的周期性信号，从共形理论中众所周知的“软炸弹”事件，以及暗相变和通常少量的暗辐射。
Five-dimensional braneworld constructions in anti-de Sitter space naturally lead to dark sector scenarios in which parts of the dark sector vanish at high 4d momentum or temperature. In the language of modified gravity, such feature implies a new mechanism for hiding light scalars, as well as the possibility of UV-completing chameleon-like effective theories. In the language of dark matter phenomenology, the high-energy behavior of the mediator sector changes dark matter observational complementarity. A multitude of signatures—including exotic ones—are present from laboratory to cosmological scales, including long-range forces with non-integer behavior, periodic signals at colliders, “soft bombs” events well-known from conformal theories, as well as a dark phase transition and a typically small amount of dark radiation.
