论文摘要
我们通过使用以色列连接条件来研究周围过度旋转裸奇异性的真空衰变。我们发现，如果Higgs场在较高的能量尺度下开发第二个最小值，那么旋转的小质量裸露的奇异性可能会导致宇宙时代内的真空衰变。由于角度从奇异性到真空气泡壁的角动量传输，可能会在奇异性周围形成事件范围。新形成的事件范围导致Bekenstein-Hawking熵的增加，这有助于提高真空衰减速率。我们得出的结论是，在宇宙学时期，事件范围可能会隐藏小质量的赤裸裸的奇异性。
We investigate a vacuum decay around an over-spinning naked singularity by using the Israel junction condition. We found that if the Higgs field develops the second minimum at higher energy scale, a spinning small-mass naked singularity could cause the vacuum decay around it within the cosmic age. An event horizon may form around the singularity due to the angular momentum transport from the singularity to a vacuum bubble wall. The newly formed event horizon leads to the increase of Bekenstein-Hawking entropy, which contributes to the enhancement of the vacuum decay rate. We conclude that small-mass naked singularities may be hidden by the event horizon within the cosmological time.
