摘要:

我们确定了短基线相干弹性中微子-核散射(CE $ν$ NS)实验的灵敏度,实验中使用了一个π衰变的静止中微子源作为探测轻子扇区中的非么正性,正如在低尺度I型跷跷板计划所预期的那样。我们还确定了最佳的配置,探测轻无菌中微子在未来吨级液氩CE $ν$ NS实验,估计预计的灵敏度上的无菌中微子参数。可能的实验装置在Spinning中子源,Lujan设施和欧洲Spinning源进行了讨论。只要系统的不确定性仍在控制之下,我们发现,CE $ν$ NS实验将具有竞争力的振荡测量从长远来看。

英文摘要:

We determine the sensitivities of short-baseline coherent elastic neutrino-nucleus scattering (CE$ν$NS) experiments using a pion decay at rest neutrino source as a probe for nonunitarity in the lepton sector, as expected in low-scale type-I seesaw schemes. We also identify the best configuration for probing light sterile neutrinos at future ton-scale liquid argon CE$ν$NS experiments, estimating the projected sensitivities on the sterile neutrino parameters. Possible experimental setups at the Spallation Neutron Source, Lujan facility and the European Spallation Source are discussed. Provided that systematic uncertainties remain under control, we find that CE$ν$NS experiments will be competitive with oscillation measurements in the long run.
