论文摘要

我们检查了80 K处的锗中淬火因子(QF)的最新测量,注意到了许多不一致之处,这些不一致能够影响与Lindhard在亚基核电弯能能源方面与Lindhard引起的离子形式主义的协议。也就是说,在这种量表中,能量量表的不确定性低估了,对大型工具性非线性的缺失,能够在低能下严重扭曲QF行为,有利于降低的值。扩展了讨论以检查QF模型选择对使用CE $ν$ NS数据的中微子电磁特性的研究的影响,该数据支持在3.5 $σ$级别下支持非零电荷。

We examine a recent measurement of the quenching factor (QF) in germanium at 80 K, noticing a number of inconsistencies capable of affecting a claimed agreement with Lindhard's ion-stopping formalism in the sub-keV nuclear recoil energy regime. Namely, an underestimated uncertainty in the energy scale and a missing correction for a large instrumental non-linearity in this scale able to severely distort the QF behavior at low energy, favoring reduced values. The discussion is expanded to inspect the impact of QF model selection on a study of neutrino electromagnetic properties using CE$ν$NS data that supports a non-zero electric charge at the 3.5 $σ$ level.
