论文摘要
我们确定了使用REST NETRINO在Lepton行业中的静脉中微子源作为对非军事的探针的敏感性（CE $ν$ ns）实验的敏感性，正如预期的那样，在低规模的类型I SeeSaw方案中。我们还确定了在未来的吨位液体氩气$ν$ ns实验上探测轻型无菌中微子的最佳配置，从而估计了对无菌中微子参数的敏感性。讨论了散布中子来源，卢扬设施和欧洲剥落源的可能实验设置。只要系统的不确定性仍处于控制之中，我们发现CE $ν$ ns实验从长远来看将具有振荡测量的竞争力。
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.
