标题： A Unified picture of Dark Matter and Dark Energy from Invisible QCD

摘要： 在一篇相关论文中已经表明，宇宙的晚期加速膨胀可以通过将QCD色对称扩展到一个$SU(3)$隐形领域（IQCD）来解释。 在本工作中，我们讨论了一个统一的框架，其中暗手征破缺的尺度决定了宇宙的加速膨胀以及暗物质的起源。 我们发现，暗夸克和胶子的强相互作用和引力动力学最终演化形成奇特的暗星。 我们根据暗大爆炸核合成来讨论这些暗致密天体的动力学复杂性。 我们认为IQCD倾向于由非常致密的暗中子星、奇异/夸克星和黑洞组成的晕，其质量为$M_{MACHO}< 10^{-7}M_{\odot}$。 这避免了MACHO和EROS合作组以及集群的限制。 我们还讨论了在暗物质搜索中的可能现象学影响。 我们认为暗超新星和暗双星可以发射出可通过LIGO/VIRGO合作组以及专门研究这些方面的未来项目检验的特殊引力波信号。 显示英文摘要

摘要： It has been shown in a companion paper that the late time acceleration of the universe can be accounted for by an extension of the QCD color to a $SU(3)$ invisible sector (IQCD). In this work we discuss a unified framework such the scale of dark chiral-breaking dictates both the accelerated expansion of the universe, and the origin of dark matter. We find that the strong and gravitational dynamics of dark quarks and gluons evolve to eventually form exotic dark stars. We discuss the dynamical complexity of these dark compact objects in light of dark big bang nucleosynthesis. We argue how IQCD favors a halo composed of very compact dark neutron stars, strange/quark stars and black holes, with masses $M_{MACHO}< 10^{-7}M_{\odot}$. This avoids limit from MACHO and EROS collaborations as well as limit from clusters. We also discuss possible phenomenological implications in dark matter searches. We argue that dark supernovae and dark binaries can emit very peculiar gravitational waves signal testable by the LIGO/VIRGO collaboration and future projects dedicated to these aspects.
