论文摘要
我们在带电电流（CC）非标准中微子相互作用（NSI）的背景下构建了β-minus衰减率扰动。特别是，我们首先概述了一个NSI参数化，用于建模CC NSI。然后，我们证明，受Beta-minus衰减数据约束的NSI强度与先前报道的一般CC NSI的界限相当，$ \ Mathcal {o}（10^{ - 4}）$ to $ \ Mathcal {o}（10^{ - 2}）$。在讨论了β-minus衰减NSI涉及的可能参数之后，我们建立了一个工作框架，以探测核衰减率的新物理学。最后，我们确定当前的核反应堆技术可用于对这些NSI参数敏感的实验。这些将包括来自两种参数的NSI贡献：（i）三种中微子风味的相对NSI效应，以及（ii）通过衰减样品的电子中微子通量变化。
We frame beta-minus decay rate perturbations in the context of charged-current (CC) nonstandard neutrino interactions (NSI). In particular, we first outline one NSI parameterization for modeling the CC NSI. Then, we demonstrate that the strength of the NSI constrained by beta-minus decay data is comparable to previously reported bounds on general CC NSI at $\mathcal{O}(10^{-4})$ to $\mathcal{O}(10^{-2})$. After discussing possible parameters involved in beta-minus decay NSI, we establish a working framework to probe potentially new physics in nuclear decay rates. Finally, we determine that current nuclear reactor technology could be used for experiments that are sensitive to these NSI parameters. These would include NSI contributions from two types of parameters: (i) the relative NSI effects from the three neutrino flavors and (ii) the change in flux of electron neutrinos through a decaying sample.
