论文摘要
非标准相互作用（NSIS）是亚抑制作用，通常出现在SM的各种扩展中，这可能会通过物质影响中微子振荡。探索NSI在正在进行的和即将进行的精确中微子振荡实验中的影响非常重要且有趣。在这项工作中，我们研究了三个即将到来的长基线（LBL）实验（沙丘，T2HK，T2HKK）的标量介导的NSI的烙印。标量NSI的影响似乎是对中微子质量项的中微子质量校正。它的贡献随物质密度线性缩放，使LBL实验成为探测其效果的合适候选者。我们表明，标量NSI可能会显着影响振荡概率，检测器的事件发生率和$δ_{CP} $测量值的$χ^2 $ - 敏感性。我们介绍了涉及LBL实验（Dune+T2HK，Dune+T2HKK，Dune+T2HK+T2HKK）的组合分析的结果，该分析具有更好地约束标量NSI参数以及对CP-violation的敏感性的更好能力。
The Non-Standard Interactions (NSIs) are subdominant effects, often appearing in various extensions of SM, which may impact the neutrino oscillations through matter. It is important and interesting to explore the impact of NSIs in the ongoing and upcoming precise neutrino oscillations experiments. In this work, we have studied the imprints of a scalar-mediated NSI in three upcoming long-baseline (LBL) experiments (DUNE, T2HK, T2HKK). The effects of scalar NSI appears as a medium-dependent correction to the neutrino mass term. Its contribution scales linearly with matter density, making LBL experiments a suitable candidate to probe its effects. We show that the scalar NSI may significantly impact the oscillation probabilities, event rates at the detectors and the $χ^2$-sensitivities of $δ_{CP}$ measurements. We present the results of a combined analysis involving the LBL experiments (DUNE+T2HK, DUNE+T2HKK, DUNE+T2HK+T2HKK) which offer a better capability of constraining the scalar NSI parameters as well as an improved sensitivity towards CP-violation.
