论文摘要
物质的中微子振荡提供了新物理学的独特探针。近年来，我们利用NOVA和T2K的中微子外观数据出现，我们研究了振荡数据中CP侵入中微子非标准相互作用的存在。我们首先展示如何简单地近似预期的NSI参数以分析两个长基线外观实验之间的差异。然后，通过将最新的NOVA和T2K数据结合在一起，我们发现CP侵入的NSI诱人的提示更喜欢一个接近最大的新复杂阶段：$ ϕ_ {eμ} $或$ ϕ_ {eτ} \ ofyout3π/2 $，带有$ | | ^ em {eμ} | $ | $ | $ | ^ evist.然后，我们将长基线数据的结果与IceCube和相干的约束进行比较。
Neutrino oscillations in matter provide a unique probe of new physics. Leveraging the advent of neutrino appearance data from NOvA and T2K in recent years, we investigate the presence of CP-violating neutrino non-standard interactions in the oscillation data. We first show how to very simply approximate the expected NSI parameters to resolve differences between two long-baseline appearance experiments analytically. Then, by combining recent NOvA and T2K data, we find a tantalizing hint of CP-violating NSI preferring a new complex phase that is close to maximal: $ϕ_{eμ}$ or $ϕ_{eτ}\approx3π/2$ with $|ε_{eμ}|$ or $|ε_{eτ}|\sim0.2$. We then compare the results from long-baseline data to constraints from IceCube and COHERENT.
