加速系中的中微子振荡
Neutrino oscillations in accelerated frames
摘要：
本文从匀加速观测者的观点讨论真空中的中微子振荡。引入了量子相位的协变定义，目的是将振荡振幅的标准表达式推广到加速标架。作为说明，我们解决了一个简化的相对论中微子双味模型，表明惯性效应对通常的Pontecorvo公式是密切相关的能量红移。唯象方面的大气中微子的背景下进行了初步分析。最后，我们讨论了一个gedanken实验，以研究我们的形式主义制度的极端加速。
英文摘要：
We discuss neutrino oscillations in vacuum from the point of view of a uniformly accelerated observer. A covariant definition of quantum phase is introduced with the aim of generalizing the standard expression of the oscillation amplitude to the accelerating frame. By way of illustration, we address a simplified two-flavor model with relativistic neutrinos, showing that inertial effects on the usual Pontecorvo formula are intimately related to the energy redshift. Phenomenological aspects are preliminarily analyzed in the context of atmospheric neutrinos. Finally, we discuss a gedanken experiment in order to investigate our formalism in regime of extreme acceleration.
