我们在近似对齐的Higgs有效场理论的框架下研究了原初黑洞从一阶电弱相变的产生，其中非解耦量子效应得到了恰当的描述.由于这种原始黑洞的质量估计约为太阳质量的10− 5，目前和未来的微透镜观测，如斯巴鲁HSC，OGLE，PRIME和罗马太空望远镜可能能够探测电弱相变。我们研究了原始黑洞可以由一阶电弱相变产生的参数区域，并探讨了它们在这些观测下的可探测性。本文还讨论了原初黑洞观测、引力波观测和对撞机实验的互补性，以检验电弱相变的性质。
We investigate production of primordial black holes from first-order electroweak phase transition in the framework of the nearly aligned Higgs effective field theory, in which non-decoupling quantum effects are properly described. Since the mass of such primordial black holes is evaluated to be about 10− 5 of the solar mass, current and future microlensing observations such as Subaru HSC, OGLE, PRIME and Roman Space Telescope may be able to probe the electroweak phase transition. We study parameter regions where primordial black holes can be produced by the first-order electroweak phase transition, and explore their detectability at these observations. Complementarity of primordial black hole observations, gravitational wave observations and collider experiments is also discussed for testing the nature of the electroweak phase transition.
