黑洞引发的标准模型重子数破坏
Standard Model Baryon Number Violation Seeded by Black Holes
摘要：
我们表明，黑洞的史瓦西半径的顺序的电弱标度可以作为种子的重子数违反内的标准模型通过sphaleron过渡。相应的速率比纯真空中的速率要快，并且在经历了电弱相变后的宇宙演化过程中，黑洞周围的重子数可以发生破坏。然而，我们表明，这不会对宇宙中预先存在的重子不对称性构成任何威胁。
英文摘要：
We show that black holes with a Schwarzschild radius of the order of the electroweak scale may act as seeds for the baryon number violation within the Standard model via sphaleron transitions. The corresponding rate is faster than the one in the pure vacuum and baryon number violation around black holes can take place during the evolution of the universe after the electroweak phase transition. We show however that this does not pose any threat for a pre-existing baryon asymmetry in the universe.
