论文摘要
在沙丘实验的框架内检查了违反等效原理（VEP）的违反（VEP）的许多不同影响。我们研究了由于我们对VEP的不认识而引起的误导性中微子振荡参数区域的可能性。此外，我们评估了对沙丘上中微子质量层次结构的测量的影响。此外，施加了将中微子重力本征态施加到具有各种基质质地的VEP上的限制。我们的研究中的一个额外任务是对哈密顿式的添加术语设定限制，考虑到不同的能源依赖性（$ e^n $，$ n = 0,1,2,3 $），这可能与标准模型扩展中定义的lorentz违反术语相关的术语。为了了解我们的结果，得出了近似的分析三个中微子振荡概率公式。
A number of different effects of the violation of the Equivalence Principle (VEP), taken as sub-leading mechanism of neutrino flavor oscillation, are examined within the framework of the DUNE experiment. We study the possibility of obtaining a misleading neutrino oscillation parameter region caused by our unawareness of VEP. Additionally, we evaluate the impact on the measurement of CP violation and the distinction of neutrino mass hierarchy at DUNE. Besides, limits on VEP for a wide variety of textures of the matrix that connects neutrino gravity eigenstates to flavor eigenstates are imposed. An extra-task of our study is to set limits on Hamiltonian added terms considering different energy dependencies ($E^n$, with $n=0,1,2,3$) that can be associated to the usual Lorentz violating terms defined in the Standard Model Extension Hamiltonian. In order to understand our results, approximated analytical three neutrino oscillation probability formulae are derived.
