论文摘要
通过非标准的相互作用参数，可以方便地纳入中微子部门中标准模型以外的物理学的影响。假设以尺寸-6矢量运算符的形式采用新物理学，对中微子振荡数据的最新全球分析（包括相干实验的结果）表明两个有利的新物理场景。这些是参数的LMA-LIGHT（具有正常的质量顺序）\＆LMA-Dark（具有倒数质量排序）扇区。在这项工作中，我们研究了新物理溶液对leggett-garg-type（LGTI）不平等的影响，该不平等量量化了系统中的时间相关性以及风味熵和真正的三方纠缠，可以将其视为空间相关的度量。我们表明，在沙丘实验设置中，违反$ν_μ$能量的LGTI不仅可以表明存在新物理学的迹象，而且预计这种新物理学将以倒入订购的LMA-Dark部门的形式。此外，我们表明，与其SM预测相比，LMA-Light解决方案通常会降低量子相关性的所有度量的值。另一方面，深色解决方案可以显着提高这些措施的值。
Effects of physics beyond the standard model in the neutrino sector are conveniently incorporated through non-standard interaction parameters. Assuming new physics in the form of dimension-6 vector operators, a recent global analysis of neutrino oscillation data including results from COHERENT experiment suggests two favorable new physics scenarios. These are LMA-Light (with normal mass ordering) \& LMA-Dark (with inverted mass ordering) sectors of parameters. In this work, we study the effects of new physics solutions on Leggett-Garg-type (LGtI) inequality which quantifies temporal correlations in the system along with flavor entropy and genuine tripartite entanglement which can be considered as measures of spatial correlations. We show that the violation of LGtI for $ν_μ$ energy around 3 GeV in the DUNE experimental set-up can not only be an indication of presence of new physics but such a new physics is expected to be in the form of LMA-Dark sector with inverted ordering. Further, we show that the LMA-Light solution, in general, decreases the values of all measures of quantum correlations in comparison to their SM predictions. On the other hand, the Dark solution can significantly enhance the values of these measures.
