如何发现镜像星

How To Discover Mirror Stars

David Curtin, Jack Setford

摘要:

非最小隐藏扇区是一种重要的通用可能性,并出现在高度动机的理论中,如中性自然。因此,一小部分暗物质可能具有类似于标准物质(SM)、电磁学和核物理学的隐藏相互作用。这导致了\emph{Mirror Stars}的形成:暗区类似于以暗光子发光的规则恒星。我们第一次在观测中研究了镜像星的可见特征。如果暗光子和可见光子有一个小的动力学混合,SM物质被捕获在镜星的核心,产生一个类似于但比白矮星微弱得多的光学信号,以及一个单独的X射线信号,代表一个直接进入镜星核心的窗口。这种强大而独特的特征是镜像星的确凿证据,可以在光学和X射线搜索中发现。

英文摘要:

Non-minimal hidden sectors are an important generic possibility and arise in highly motivated theories like Neutral Naturalness. A fraction of dark matter could therefore have hidden interactions analogous to Standard Matter (SM) electromagnetism and nuclear physics. This leads to the formation of \emph{Mirror Stars}: dark-sector analogues of regular stars that shine in dark photons. We examine the visible signatures of Mirror Stars in observations for the first time. If the dark and visible photon have a small kinetic mixing, SM matter is captured in Mirror Star cores, giving rise to an optical signal similar to but much fainter than white dwarfs, as well as a separate X-ray signal that represents a direct window into the Mirror Star core. This robust and highly distinctive signature is a smoking gun of Mirror Stars and could be discovered in optical and X-ray searches.
