摘要：
随着新实验的建设，尤其是在几GeV能量范围内的实验推进，中微子物理学正迈入精确时代。在该能量范围内，中微子与核子和原子核存在多种相互作用。本研究特别聚焦中微子-原子核准弹性截面，在有效场论（EFT）框架内同时纳入了标准相互作用，并首次纳入了非标准相互作用。这些截面的主要不确定性来源于核子层面形状因子的不确定性，以及求解原子核多体问题所需的近似处理。我们探究了这些不确定性如何影响中微子实验探测由左手、右手、标量、赝标量和张量相互作用引入的新物理的潜力。对于其中部分相互作用，截面会得到增强，这使得长基线实验成为搜寻这类相互作用的绝佳场所。我们的结果（包括所有相互作用类型和所有中微子味的截面表格数据）可为此类搜寻工作提供基础。
英文摘要：
Neutrino physics is advancing into a precision era with the construction of new experiments, particularly in the few GeV energy range. Within this energy range, neutrinos exhibit diverse interactions with nucleons and nuclei. This study delves in particular into neutrino--nucleus quasi-elastic cross sections, taking into account both standard and, for the first time, non-standard interactions, all within the framework of effective field theory (EFT). The main uncertainties in these cross sections stem from uncertainties in the nucleon-level form factors, and from the approximations necessary to solve the nuclear many-body problem. We explore how these uncertainties influence the potential of neutrino experiments to probe new physics introduced by left-handed, right-handed, scalar, pseudoscalar, and tensor interactions. For some of these interactions the cross section is enhanced, making long-baseline experiments an excellent place to search for them. Our results, including tabulated cross sections for all interaction types and all neutrino flavors, can serve as the foundation for such searches.
