隐光子暗物质与类轴子相互作用

Hidden Photon Dark Matter Interacting via Axion-like Particles

Paola Arias, Ariel Arza, Joerg Jaeckel, Diego Vargas-Arancibia

摘要:

我们研究的情况下,宇宙中的暗物质是由非常轻的隐藏光子下的$Z_{2}$对称变换。与通常的情况相反,动力学混合被对称性所禁止,并且暗光子仅通过充当“信使”的类轴子粒子与标准模型光子相互作用。专注于签名涉及普通光子,我们的调查的现象学包括宇宙学的稳定性,CMB扭曲,天体物理能量损失,光照射通过墙壁实验,太阳镜和太阳X射线观测的限制。

英文摘要:

We investigate a scenario where the dark matter of the Universe is made from very light hidden photons transforming under a $Z_{2}$-symmetry. In contrast to the usual situation, kinetic mixing is forbidden by the symmetry and the dark photon interacts with the Standard Model photon only via an axion-like particle acting as a "messenger". Focusing on signatures involving the ordinary photon, our survey of the phenomenology includes limits from cosmological stability, CMB distortions, astrophysical energy loss, light-shining-through-walls experiments, helioscopes and solar X-ray observations.
