论文摘要
在Beta-Decay实验中直接检测遗物中微子是一个雄心勃勃的目标，长期以来一直超出了可用技术的影响力。对于此类实验，最具挑战性的实际困难之一是管理大量放射性材料，而不会损害将有用事件与实质性β-赛背景区分开所需的能量分辨率。托勒密项目通过将放射性材料存放在石墨烯上，为该问题提供了创新的解决方案。尽管这种方法有望应对主要挑战，但由于β衰减者靠近固态系统，它引入了新问题。在这项工作中，我们专注于由β-赛事事件引起的石墨烯电子系统的效果。我们计算由这种改动导致的遗物中微子峰的失真，分析失真对中微子捕获事件可见性的影响，并讨论潜在的技术解决方案以增强这些事件的可见性。
Direct detection of relic neutrinos in a beta-decay experiment is an ambitious goal that has long been beyond the reach of available technology. One of the most challenging practical difficulties for such an experiment is managing a large amount of radioactive material without compromising the energy resolution required to distinguish useful events from the substantial beta-decay background. The PTOLEMY project offers an innovative solution to this problem by depositing radioactive material on graphene. While this approach is expected to address the main challenge, it introduces new issues due to the proximity of the beta decayers to a solid-state system. In this work, we focus on the effect of the shakeup of the graphene electron system caused by a beta-decay event. We calculate the distortion of the relic neutrino peaks resulting from this shakeup, analyze the impact of the distortion on the visibility of neutrino capture events, and discuss potential technological solutions to enhance the visibility of these events.
