论文摘要
尽管已知中微子质量状态之间的质量差异，但尚未确定它们的绝对质量和质量层次结构。确定中微子的质量提供了超出标准模型以外的物理的访问，并且由此产生的价值对宇宙历史上大规模结构的增长有影响。由于该主题的重要性，已经进行了许多努力，以确定中微子的质量，包括直接的运动学测量和天体物理现象的间接测量，这些测量通过宇宙进化模型来限制质量特征状态的总和。在这里，我们主张使用163HO衰减的量热测量测量来对有效的电子中微子质量进行运动学确定。当前实验的成功，其高收益与成本比率，具有不同系统误差的方法的值以及测量电子中微子质量而不是电子抗中性抗质量的值，这项工作是合理的。
While the mass differences between neutrino mass states are known, their absolute masses and mass hierarchy have not yet been determined. Determining the mass of neutrinos provides access to physics beyond the Standard Model and the resulting value has implications for the growth of large-scale structure in the universe over cosmic history. Because of the importance of the topic, a number of efforts are already underway to determine the mass of neutrinos including direct kinematic measurements and indirect measurements of astrophysical phenomena that constrain the sum of the mass eigenstates through models of cosmic evolution. Here, we advocate for a collaborative international effort to perform a kinematic determination of the effective electron neutrino mass using calorimetric measurements of the decay of 163Ho. This effort is justified by the success of current experiments using the technique, its high benefit-to-cost ratio, the value of approaches with different systematic errors, and the value of measuring the electron neutrino mass rather than the electron anti-neutrino mass.
