标题： Non-Standard Neutrino Interactions at Neutrino Experiments and Colliders

摘要： 新物理对中微子与其他粒子相互作用的影响可以通过一组称为非标准中微子相互作用（NSI）的有效四费米子算符来参数化。 这一NSI框架对于研究不同类型的中微子实验之间的互补性很有用。 在这项工作中，我们进一步比较了中微子实验与高能对撞机实验的探测范围。 由于高能对撞机经常探测与四费米子算符相关的质量尺度，有效场论方法变得无效，必须利用明确的模型。 我们研究了一系列具有代表性的简化模型，包括新的U(1)规范玻色子、标量轻子夸克和重中性轻子。 对于每一种模型，我们检查了由当前和未来中微子实验的NSI限制以及大型强子对撞机和计划中的电子-正电子及$\mu$子对撞机的数据所约束的模型参数空间。 我们发现，在我们研究的模型中，除了可能的$\mu$子亲和轻子夸克和与电子或$\mu$子中微子混合的重中性轻子外，对撞机搜索比中微子测量更具有约束力。 此外，我们简要讨论了获得中微子实验最具约束力模型的其他模型构建可能性。 显示英文摘要

摘要： The impact of new physics on the interactions of neutrinos with other particles can be parametrized by a set of effective four-fermion operators called non-standard neutrino interactions (NSIs). This NSI framework is useful for studying the complementarity between different types of neutrino experiments. In this work, we further compare the reach of neutrino experiments with high-energy collider experiments. Since high-energy colliders often probe the mass scale associated with the four-fermion operators, the effective field theory approach becomes invalid and explicit models must be utilized. We study a variety of representative simplified models including new U(1) gauge bosons, scalar leptoquarks, and heavy neutral leptons. For each of these, we examine the model parameter space constrained by NSI bounds from current and future neutrino experiments, and by data from the Large Hadron Collider and planned electron-positron and muon colliders. We find that in the models we study, with the possible exceptions of muon-philic leptoquarks and heavy neutral leptons mixing with electron or muon neutrinos, collider searches are more constraining than neutrino measurements. Additionally, we briefly comment on other model building possibilities for obtaining models where neutrino experiments are most constraining.
