论文摘要
我们证明了黑洞质量差距的力量，作为基本物理学的新型探测。与标准模型相对的新的光颗粒可以充当人口恒星核心核心的额外能量损失来源，从而极大地改变了它们的演变。我们研究了两个范式弱耦合，低质量颗粒，轴和隐藏光子的影响，并发现脉动对不稳定性造成了大量的质量损失。结果，可以形成$ 72 \ msun $或更重的黑洞，深处是标准型号预测的黑洞质量间隙。质量差距的上边缘提高到$> 130美元{\ rm m} _ \ odot $，这意味着在Ligo的灵敏度升级后会观察到较重的黑洞，也将受到影响。相比之下，热产生的重颗粒将保留在核心中，从而导致诱人的可能性，它们可以驱动类似于电子峰值对的新不稳定性。我们通过分析研究这种效果，发现避免电子旋律对不稳定性的恒星可能会经历这种新的不稳定性。我们根据二进制黑洞合并的电流和即将到来的重力波干涉仪检测来讨论我们的结果。
We demonstrate the power of the black hole mass gap as a novel probe of fundamental physics. New light particles that couple to the Standard Model can act as an additional source of energy loss in the cores of population-III stars, dramatically altering their evolution. We investigate the effects of two paradigmatic weakly coupled, low-mass particles, axions and hidden photons, and find that the pulsational pair instability, which causes a substantial amount of mass loss, is suppressed. As a result, it is possible to form black holes of $72\msun$ or heavier, deep inside the black hole mass gap predicted by the Standard Model. The upper edge of the mass gap is raised to $>130{\rm M}_\odot$, implying that heavier black holes, anticipated to be observed after LIGO's sensitivity is upgraded, would also be impacted. In contrast, thermally produced heavy particles would remain in the core, leading to the tantalizing possibility that they drive a new instability akin to the electron-positron pair instability. We investigate this effect analytically and find that stars that avoid the electron-positron pair instability could experience this new instability. We discuss our results in light of current and upcoming gravitational wave interferometer detections of binary black hole mergers.
