摘要：
在β衰变实验中直接探测遗迹中微子是一个宏伟目标，长期以来一直超出可用技术的能力范围。此类实验最具挑战性的实际困难之一，是在管理大量放射性物质的同时，不损害区分有用事件与大量β衰变背景所需的能量分辨率。PTOLEMY项目通过将放射性物质沉积在石墨烯上，为这一问题提供了创新解决方案。尽管该方法有望应对主要挑战，但由于β衰变体靠近固态系统，它也带来了新的问题。在本工作中，我们聚焦于β衰变事件引起的石墨烯电子系统激扰效应。我们计算了这种激扰导致的遗迹中微子峰畸变，分析了该畸变对中微子俘获事件可见度的影响，并讨论了提高这些事件可见度的潜在技术解决方案。
英文摘要：
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.
