论文摘要
原始黑洞(PBHS)的霍金蒸发可以促进物质 - 抗逆点的不对称产生。我们专注于在大爆炸核合成之前短暂主导并蒸发的超低质量PBH。我们通过在未来的GW观测值中检测到其特征性峰值引力波(GW)频谱来对这种情况提出新的测试。在这里,由于PBH分布,二阶的源张量扰动而导致的一阶绝热扰动以及来自二阶源张量扰动引起的等效性扰动,并导致诱导GW背景的两个峰。这些共振峰是在以前以PBH为主导的时代的情况下在标准辐射统治开始时产生的。这种独特的GW光谱形状将为蒸发PBH提供非热男性生成的吸烟枪信号,否则由于涉及非常高的能量尺度或黑暗部门与可见扇形的微弱相互作用,在实验室实验中否则不可能进行测试。
Hawking evaporation of primordial black holes (PBHs) can facilitate the generation of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the universe and evaporate before the big bang nucleosynthesis. We propose a novel test of this scenario by detecting its characteristic doubly peaked gravitational wave (GW) spectrum in future GW observatories. Here the first order adiabatic perturbation from inflation and from the isocurvature perturbations due to PBH distribution, source tensor perturbations in second-order and lead to two peaks in the induced GW background. These resonant peaks are generated at the beginning of standard radiation domination in the presence of a prior PBH-dominated era. This unique GW spectral shape would provide a smoking gun signal of non-thermal baryogenesis from evaporating PBHs, which is otherwise impossible to test in laboratory experiments due to the very high energy scales involved or the feeble interaction of the dark sector with the visible sector.
