Recently, a concept known as μTRISTAN, which involves the acceleration of μ+, has been proposed. This initiative has led to considerations of a new design for a neutrino factory. Additionally, leveraging the polarization of μ+, measurements of T violation in neutrino oscillations are also being explored. In this paper, we present analytical expressions for T violation in neutrino oscillations within the framework of standard three-flavor neutrino oscillations, a scenario involving nonstandard interactions, and a case of unitarity violation. We point out that examining the energy spectrum of T violation may be useful for probing new physics effects.
最近，一种被称为μTRISTAN的概念被提出，它涉及μ⁺的加速。这一举措引发了对中微子工厂新设计的思考。此外，利用μ⁺的极化，人们也在探索中微子振荡中T破坏的测量方法。在本文中，我们给出了标准三味中微子振荡框架内、涉及非标准相互作用的情形以及幺正性破坏情形下中微子振荡中T破坏的解析表达式。我们指出，研究T破坏的能谱可能有助于探测新物理效应。
