标题： Neutrino spin oscillations in gravitational fields in higher dimensions

摘要： 中微子物理是粒子物理、宇宙学和天体物理学领域中最活跃的研究方向之一，具有重要意义。另一方面，受一些理论（包括弦理论）的启发，在超过四个时空维度中构建物理理论近年来受到了越来越多的关注。中微子与引力场的相互作用是一种有趣的现象，可能导致不同螺旋态之间的转换（自旋振荡）。我们研究了高维引力场中史瓦西和RN背景下的中微子自旋振荡。我们计算了随时间变化的转换概率，并且还研究了振荡频率对轨道半径的依赖关系。这些结果有助于我们更好地理解高维空间中的引力和中微子的行为。 显示英文摘要

摘要： 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.
