论文摘要
我们开拓黑洞质量差距是一种强大的新工具，用于限制新粒子。与标准模型耦合的新粒子（例如轴轴）是人口III恒星核心的额外损失来源，抑制了由于风而损失的质量并消除了配对的稳定性。这导致天体物理黑洞较重。例如，使用恒星模拟，我们表明太阳轴对最近的Xenon1T过量的解释意味着〜56 ms的天体物理黑洞，直接在标准模型预测的黑洞质量间隙内。
We pioneer the black hole mass gap as a powerful new tool for constraining new particles. A new particle that couples to the Standard Model---such as an axion---acts as an additional source of loss in the cores of population-III stars, suppressing mass lost due to winds and quenching the pair-instability. This results in heavier astrophysical black holes. As an example, using stellar simulations we show that the solar axion explanation of the recent XENON1T excess implies astrophysical black holes of ~ 56 MS, squarely within the black hole mass gap predicted by the Standard Model.
