论文摘要
鉴于缺乏弱相互作用的暗物质的经验证据,可以合理地研究其他候选人,例如具有与标准模型相似数量的粒子的限制黑暗扇区。 Twin Higgs Mirror Matter是一种这样的模型,它是标准模型的双胞胎,其颗粒质量比解决层次结构问题的标准模型重3--6倍。这通常可以预测镜像中子星,完全由镜子核物质制成。我们使用从地壳(核)到核心(相对论平均场模型)的状态的现实状态方程发现它们的结构,并使用晶格QCD结果扩展粒子质量。我们发现,镜像中子星有独特的特征,可通过引力波和二进制脉冲星可检测到,这为探测暗物质提供了有趣的可能性。
Given the lack of empirical evidence of weakly interacting dark matter, it is reasonable to look to other candidates such as a confining dark sector with a similar number of particles as the standard model. Twin Higgs mirror matter is one such model that is a twin of the standard model with particles masses 3--6 times heavier than the standard model that solves the hierarchy problem. This generically predicts mirror neutron stars, degenerate objects made entirely of mirror nuclear matter. We find their structure using a realistic equation of state from crust (nuclei) to core (relativistic mean-field model) and scale the particle masses using lattice QCD results. We find that mirror neutron stars have unique signatures that are detectable via gravitational waves and binary pulsars, that provides an intriguing possibility for probing dark matter.
