与暗物质有关的隐藏光子

Hidden Photons in connection to Dark Matter

Sarah Andreas, Mark D. Goodsell, Andreas Ringwald

摘要:

位于隐藏扇区中的轻额外U(1)规范玻色子,即所谓的隐藏光子,引起了人们的广泛关注,因为它们是标准模型之外许多场景的一个很好的动机特征,而且可以调解与隐藏扇区暗物质的相互作用。我们回顾限制隐藏的光子从过去的电子束转储实验,包括两个新的限制,从这样的实验在KEK和奥赛。此外,我们还研究了在暗区存在暗物质的可能性。一个简单的玩具模型和不同的超对称实现提供了可行的暗物质候选人在隐藏的部门,在最近的直接检测限协议。

英文摘要:

Light extra U(1) gauge bosons, so called hidden photons, which reside in a hidden sector have attracted much attention since they are a well motivated feature of many scenarios beyond the Standard Model and furthermore could mediate the interaction with hidden sector dark matter. We review limits on hidden photons from past electron beam dump experiments including two new limits from such experiments at KEK and Orsay. In addition, we study the possibility of having dark matter in the hidden sector. A simple toy model and different supersymmetric realisations are shown to provide viable dark matter candidates in the hidden sector that are in agreement with recent direct detection limits.
