AI 中文摘要
中微子可通过标准模型内的高阶辐射修正，或新物理领域获得电磁矩。本研究聚焦于通过黑洞的淬灭超辐射探测这些超出标准模型的中微子矩，其中费米子对可从超辐射玻色云中产生。我们考虑黑洞超辐射产生暗光子，淬灭过程通过暗光子产生中微子-反中微子对实现。对产生的效率取决于暗光子与中微子间的有效耦合，即暗电磁矩。我们还讨论了该淬灭超辐射机制对中微子背景产生的原初黑洞丰度的限制。
英文摘要
Neutrinos can acquire electromagnetic moments either within the Standard Model through higher order radiative corrections or within the domain of new physics. In this study we focus on probing these beyond the standard model neutrino moments through quenched superradiance of black holes where fermionic pairs can be produced from the superradiant bosonic cloud. We consider the production of dark photons from black hole superradiance and quenching occurs through the production of neutrino-antineutrino pairs from the dark photons. The efficiency of the pair production depends on the effective coupling between the dark photons and neutrinos, i.e., the dark electromagnetic moments. We also discuss bounds on primordial black hole abundance from neutrino background arising from this quenched superradiance mechanism.
