我们在波包形式体系中研究中微子味振荡，将标准平面波处理方法扩展，以纳入中微子质量的有限空间相干性。我们推导了包含MSW物质效应、退相干及由波包宽度决定的定域抑制的完整三味振荡概率，并以MINOS消失数据为基准，在相同参数下扩展至DUNE预测。为量化振荡数据对波包宽度的约束精度，我们针对MINOS和DUNE计算了经典费希尔信息FC随中微子能量的变化，结果显示其敏感性恰好集中在波包与平面波预测结果分歧的低能区。除振荡概率分析外，我们在量子信息论框架内计算了波粒纠缠互补性量，并针对MINOS和DUNE两个实验，探究了涉及纠缠、可预测性和可见度的完整三元性描述随中微子能量的变化。我们表明，即使振荡概率在数值上与平面波结果无法区分，波包结构仍会在这些三元性量中留下可观测印记。我们的结果证明，波包方法为在长基线大气中微子振荡实验中探测量子基础提供了理论自洽且受实验驱动的框架。
英文摘要
We investigate neutrino flavor oscillations in the wave packet formalism, extending the standard planewave treatment to incorporate the finite spatial coherence of neutrino mass eigenstates.We derive the full three flavor oscillation probability with MSW matter effects, decoherence, and localization suppression governed by the wave packet width, benchmarking against MINOS disappearance data and extending to DUNE predictions under the same parameters. To quantify how sharply the oscillation data constrain the wave packet width, we compute the classical Fisher information FC as a function of neutrino energy for both MINOS and DUNE, and show that its sensitivity is concentrated precisely in the low-energy regime where the wave-packet and plane-wave predictions diverge. Beyond the oscillation probability analysis, we compute wave particle entanglement complementarity quantities within a quantum information theoretic framework and explore the complete triality description involving entanglement, predictability, and visibility as functions of neutrino energy for both experiments such as MINOS and DUNE. We show that even when the oscillation probability is numerically indistinguishable from the planewave result, the wave packet structure leaves observable imprints in these triality measures. Our results demonstrate that the wave packet approach provides a theoretically consistent and experimentally motivated framework for probing quantum foundations in long-baseline atmospheric neutrino oscillation experiments.
