论文摘要
在最活跃的研究领域之一的中微子物理学对粒子物理，宇宙学和天体物理学具有重要意义。另一方面，以某些理论（包括弦理论，在四个时空维度中的物理理论提出）的动机一直是近年来注意力越来越多的主题。中微子与重力场的相互作用是有趣的现象之一，可以导致不同的螺旋状态之间的过渡（自旋振荡）。我们研究施瓦茨柴尔德和RN背景中的中微子自旋振荡在较高尺寸的重力场中。我们计算过渡概率作为时间的函数，并研究振荡频率对轨道半径的依赖性。结果有助于我们更好地了解更高维度的重力和中微子的行为。
Neutrino physics in one of the most active fields of research with important implications for particle physics, cosmology and astrophysics. On the other hand, motivated by some theories including string theory, formulation of physical theories in more than four space-time dimensions has been the subject of increasing attention in recent years. Interaction of neutrinos with gravitational fields is one of the interesting phenomena which can lead to transition between different helicity states (spin oscillations). We study neutrino spin oscillations in Schwarzschild and RN backgrounds in higher dimensional gravitational fields. We calculate the transition probability as a function of time and also study the dependence of the oscillation frequency on the orbital radius. The results help us to better understand the behavior of gravity and neutrinos in higher dimensions.
