Scale-invariant extensions of the electroweak theory are not only attractive because they can dynamically generate the weak scale, but also due to their role in facilitating supercooled first-order phase transitions. We study the minimal scale-invariant extension of the standard model and show that Primordial Black Holes (PBHs) can be abundantly produced. The mass of these PBHs is bounded from above by that of the moon due to QCD catalysis limiting the amount of supercooling. Lunar-mass PBHs, which are produced for dark Higgs vev , correspond to the best likelihood to explain the HSC lensing anomaly. For , the model can explain hundred per cent of dark matter. At even larger hierarchy of scales, it can contribute to the line. While the gravitational wave (GW) signal produced by the HSC anomaly interpretation is large and detectable by LISA above astrophysical foreground, the dark matter interpretation in terms of PBHs can not be entirely probed by future GW detection. This is due to the dilution of the signal by the entropy injected during the decay of the long-lived scalar. This extended lifetime is a natural consequence of the large hierarchy of scales.

来自共形希格斯粒子的原始黑洞


电弱理论的尺度不变扩展不仅具有吸引力，因为它们可以动态地产生弱尺度，而且还因为它们在促进过冷一阶相变中的作用。我们研究了标准模型的最小尺度不变扩展，并表明原始黑洞（PBH）可以大量产生。由于 QCD 催化限制了过冷量，这些 PBH 的质量从上方受到月球质量的限制。为暗希格斯粒子 vev 产生的月球质量 PBH 对应于解释 HSC 透镜异常的最佳可能性。对于 ，该模型可以百分百解释暗物质。在更大的尺度层次上，它可以为生产线做出贡献。虽然 HSC 异常解释产生的引力波 (GW) 信号很大，并且可以通过天体物理前景上方的 LISA 检测到，但未来的 GW 检测无法完全探测到 PBH 方面的暗物质解释。这是由于长寿命标量衰变期间注入的熵稀释了信号。这种延长的寿命是大尺度层次结构的自然结果。
