论文摘要
Karlsruhe Tritium Neutrino(Katrin)实验旨在测量T2β衰变端点区域的高精度积分光谱,其主要目标是探测中微子的绝对质量尺度。在2018年进行了首次tri症调试运动之后,该实验自2019年以来一直定期进行,并且在其前两个测量活动中,已经达到了Sub-ev的敏感性。经过1000天的数据获取,在90%的置信度下,Katrin的设计灵敏度为0.2 eV。在这份白皮书中,我们描述了卡特林的当前状态;探索测量中微子质量和其他物理学可观察物的前景,包括无菌中微子和其他标准模式假设;并讨论可能进一步提高Katrin敏感性的研究和发展项目。
The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-precision integral spectrum of the endpoint region of T2 beta decay, with the primary goal of probing the absolute mass scale of the neutrino. After a first tritium commissioning campaign in 2018, the experiment has been regularly running since 2019, and in its first two measurement campaigns has already achieved a sub-eV sensitivity. After 1000 days of data-taking, KATRIN's design sensitivity is 0.2 eV at the 90% confidence level. In this white paper we describe the current status of KATRIN; explore prospects for measuring the neutrino mass and other physics observables, including sterile neutrinos and other beyond-Standard-Model hypotheses; and discuss research-and-development projects that may further improve the KATRIN sensitivity.
