本研究探讨与标准模型扩展CPT偶算符相关的中微子-标量场张量非标准相互作用，分析长基线实验对相关SME系数的灵敏度，验证DUNE探测能力并指出未来实验可厘清这类相互作用。

摘要：

文献中已提出多种中微子与标量场之间的非标准相互作用。在本工作中，我们概述了中微子与标量场的张量型非标准相互作用情形，这类相互作用可与标准模型扩展（SME）的有效CPT偶4维算符相关联。此外，本文主要分析了在长基线实验配置下，对CPT偶各向同性$c_{αβ}$和Z空间$c_{αβ}^{ZZ}$型SME系数的预计灵敏度。我们研究了DUNE的具体情形，并展示了其对这类新物理的灵敏度。当前的IceCube实验以及即将开展的中微子实验（如KM3NeT、IceCube-Gen2和GRAND计划）有望厘清这类中微子非标准相互作用。

英文摘要：

Numerous non-standard interactions between neutrinos and scalar fields have been suggested in the literature. In this work, we have outlined the case of tensorial neutrino non-standard interactions with scalar fields, which can be related to the effective CPT-even dimension-4 operators of the Standard Model Extension (SME). Moreover, in this paper, we have mostly analyzed the projected sensitivities to the CPT-even isotropic $c_{αβ}$ and $Z-$spatial $c_{αβ}^{ZZ}$ SME coefficients, in the context of a long-baseline experimental configuration. We study the particular case of DUNE and show its sensitivity to this type of new physics. The current IceCube experiment and upcoming neutrino experiments such as KM3NeT, IceCube-Gen2, and GRAND proposals may clarify these classes of neutrino non-standard interactions.
