论文摘要
假真空衰减是量子场理论中的关键特征，在早期宇宙宇宙学中表现出独特的签名。最近有人提出，假真空衰减是由黑洞（BH）催化的，如果在早期宇宙中形成原始BHS，则可能导致标准模型Higgs真空的灾难。我们研究了辐射BH周围标量场的真空相变，并考虑到鹰辐射的效果。我们发现，由于标量在地平线附近稳定，真空衰减速率在存在热效应的情况下略有下降。但是，稳定效应在离地平线足够远的地方变得较弱。因此，我们发现衰减速率没有显着改变，除非标量场与辐射的有效耦合常数极大。这意味着从鹰辐射中的电势变化并不有助于防止标准模型Higgs真空衰减由BH催化的。
False vacuum decay is a key feature in quantum field theories and exhibits a distinct signature in the early Universe cosmology. It has recently been suggested that the false vacuum decay is catalyzed by a black hole (BH), which might cause the catastrophe of the Standard Model Higgs vacuum if primordial BHs are formed in the early Universe. We investigate vacuum phase transition of a scalar field around a radiating BH with taking into account the effect of Hawking radiation. We find that the vacuum decay rate slightly decreases in the presence of the thermal effect since the scalar potential is stabilized near the horizon. However, the stabilization effect becomes weak at the points sufficiently far from the horizon. Consequently, we find that the decay rate is not significantly changed unless the effective coupling constant of the scalar field to the radiation is extremely large. This implies that the change of the potential from the Hawking radiation does not help prevent the Standard Model Higgs vacuum decay catalyzed by a BH.
