We study the effect of gravity on neutrino flavor oscillations when each mass eigenstate is described by a wave packet instead of a plane wave. Two different approaches for implementing the wave packet formalism in the study of neutrino flavor oscillations in curved spacetime are examined. We work with a general static and spherically symmetric spacetime before applying our results to a few spacetime metrics of interest. We first focus on general relativity by examining the effect of the exterior and interior Schwarzschild solutions, as well as the de Sitter-Schwarzschild metric, and then we examine selected metrics from modified gravity models.

当每个质量本征态由波包而不是平面波描述时，我们研究了重力对中微子风味振荡的影响。研究了在弯曲时空中的中微子风味振荡研究中实现波包形式主义的两种不同方法。在将我们的结果应用于一些感兴趣的时空度量之前，我们使用一般静态和球对称时空。我们首先通过检查外部和内部 Schwarzschild 解以及 de Sitter-Schwarzschild 度量的影响来关注广义相对论，然后我们检查来自修改后的重力模型的选定度量。
