The LIGO-Virgo Collaboration has recently announced the detection of a heavy binary black hole merger, with component masses that are difficult to account for in standard stellar structure theory. In this Letter, we propose several explanations based on models of new physics, including new light particle losses, modified gravity, large extra dimensions, and a small magnetic moment of the neutrino. Each of these affect the physics of the pair instability differently, leading to novel mechanisms for forming black holes inside the mass gap.
激光干涉引力波天文台（LIGO）-处女座（Virgo）合作组织最近宣布探测到一次重双星黑洞合并，其组成部分的质量在标准恒星结构理论中难以解释。在本快报中，我们基于新物理模型提出了几种解释，包括新的轻粒子损失、修正引力、大额外维度以及中微子的小磁矩。这些因素对成对不稳定性的物理过程影响各异，从而导致了在质量间隙内形成黑洞的新机制。
