论文摘要
我们研究了一种场景，其中宇宙的暗物质是由在$ z_ {2} $ - 对称性下转换的非常轻的隐藏光子制成的。与通常的情况相反，对称性禁止动力学混合，而暗光子仅通过用作“ Messenger”的轴突样粒子与标准模型光子相互作用。我们对涉及普通光子的签名的关注，我们对现象学的调查包括宇宙学稳定性，CMB扭曲，天体物理能量损失，闪亮的壁壁壁画实验，旋转式镜头和太阳X射线观察的限制。
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.
