论文摘要
QCD的标准模型扩展超出标准模型的扩展可能会导致夸克和Gluon限制的温度高于$ \ sim $ gev。这些模型还可以改变QCD相变的顺序。因此，在QCD过渡时相对论自由度变化的原始黑洞（PBHS）的增强产生可能有利于小于标准模型QCD地平线量表的质量尺度的PBH的产生。因此，与与标准GEV规模QCD过渡相关的PBHS不同，此类PBH可以说明无约束的小行星质量窗口中的所有暗物质丰度。这链接超出了QCD物理学的标准模型修改，并在微透镜调查中搜索PBH的广泛范围未探索的温度制度（$ \ sim 10-10^3 $ TEV）。此外，我们讨论了这些模型对重力波实验的含义。我们表明，$ \ sim7 $ tev处的一阶QCD阶段过渡与Subaru Hyper-Suprime Cam候选事件是一致的，而$ \ sim 70 $ GEV过渡与OGLE候选事件一致，并且也可以考虑索取的Nanograv Revertational Rectitational Rectitation rationational Wave Signal。
Beyond Standard Model extensions of QCD could result in quark and gluon confinement occurring well above a temperature of $\sim$GeV. These models can also alter the order of the QCD phase transition. The enhanced production of primordial black holes (PBHs) that can accompany the change in relativistic degrees of freedom at the QCD transition therefore could favor the production of PBHs with mass scales smaller than the Standard Model QCD horizon scale. Consequently, and unlike PBHs associated with a standard GeV-scale QCD transition, such PBHs can account for all the dark matter abundance in the unconstrained asteroid-mass window. This links beyond Standard Model modifications of QCD physics over a broad range of unexplored temperature regimes ($\sim 10-10^3$ TeV) with microlensing surveys searching for PBHs. Additionally, we discuss implications of these models for gravitational wave experiments. We show that a first order QCD phase transition at $\sim7$ TeV is consistent with the Subaru Hyper-Suprime Cam candidate event, while a $\sim 70$ GeV transition is consistent with OGLE candidate events, and also could account for the claimed NANOGrav gravitational wave signal.
