扭曲的黑暗区

The Warped Dark Sector

Philippe Brax, Sylvain Fichet, Philip Tanedo

摘要:

反德西特空间中的五维膜世界构造自然会导致暗区场景,其中部分暗区在高4d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。用暗物质现象学的语言来说,介质扇区的高能行为改变了暗物质观测的互补性。众多的签名-包括异国情调的-目前从实验室到宇宙学尺度,包括远程部队与非整数行为,周期性信号在对撞机,“软炸弹”事件众所周知的共形理论,以及一个黑暗的相变和一个典型的少量的黑暗辐射。

英文摘要:

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 behaviour of the mediator sector changes dark matter observational complementarity. A multitude of signatures---including exotic ones---are present from laboratory to cosmologic scales, including long-range forces with non-integer behaviour, 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.
