Neutrino physics is one of the most important topics in particle physics and cosmology. As it is known, neutrinos are weakly interacting fundamental particles with chargeless and very small masses. One of the most characteristic features of the neutrino that make a difference from other elementary particles is that it oscillates between the mass and flavour eigenstates. Due to these oscillations, neutrinos change from one flavour to another. So far in theory the possible effects of deformed space-time effects on oscillation have not been considered. In this study, we show for the first time that a deformed space-time metric will lead to fractional dynamics between mass and flavour changes and therefore cause a phase shift in the oscillation period. We also shortly discuss the possible relation between anomalous cyclic and relic neutrinos. The modification in the oscillation probabilities due to the studied effect in this work could be seen using relic neutrinos.
中微子物理学是粒子物理学和宇宙学中最重要的课题之一。众所周知,中微子是弱相互作用的基本粒子,不带电荷且质量极小。中微子与其他基本粒子的一个最显著区别特征是它在质量本征态和味本征态之间振荡。由于这些振荡,中微子会从一种味转变为另一种味。到目前为止,理论上尚未考虑变形时空效应在振荡方面的可能影响。在本研究中,我们首次表明变形时空度规会导致质量和味变化之间的分数动力学,从而在振荡周期中引起相移。我们还简要讨论了反常循环中微子和遗迹中微子之间的可能关系。利用遗迹中微子可以看到由于本工作中所研究的效应而导致的振荡概率的变化。
