论文摘要
在基于大统一理论(GUTS)的男性生成模型中,宇宙的重子不对称是通过CP和BARYON数量违反的,在非常早期宇宙中非常巨大的仪表或Higgs玻色子的不平衡衰减。然而,最近对通货膨胀量表和随后再加热温度的限制构成了许多此类模型的压力。在本文中,我们考虑了原始黑洞可能在肠道男性生成过程中发挥的作用。通过霍金蒸发,无论这些颗粒的质量或早期宇宙的温度如何,黑洞都可以有效地产生肠道或仪表玻色子。此外,在参数空间的重要区域中,电动相过渡后的黑洞蒸发,自然地避免了基于$ su(5)$的肠模型中通常遇到的Sphaleron洗涤问题。我们确定了各种各样的场景,在这些情况下,黑洞可以通过肠道玻色子的生产和腐烂来促进重子不对称的产生。
In models of baryogenesis based on Grand Unified Theories (GUTs), the baryon asymmetry of the universe is generated through the CP and baryon number violating, out-of-equilibrium decays of very massive gauge or Higgs bosons in the very early universe. Recent constraints on the scale of inflation and the subsequent temperature of reheating, however, have put pressure on many such models. In this paper, we consider the role that primordial black holes may have played in the process of GUT baryogenesis. Through Hawking evaporation, black holes can efficiently generate GUT Higgs or gauge bosons, regardless of the masses of these particles or the temperature of the early universe. Furthermore, in significant regions of parameter space, the black holes evaporate after the electroweak phase transition, naturally evading the problem of sphaleron washout that is normally encountered in GUT models based on $SU(5)$. We identify a wide range of scenarios in which black holes could facilitate the generation of the baryon asymmetry through the production and decays of GUT bosons.
