洛伦兹不变性破坏下的高能中微子振荡

High energy neutrino oscillation at the presence of the Lorentz Invariance Violation

Iman Motie, She-Sheng Xue

摘要:

由于普朗克尺度下的量子引力涨落,时空流形不再是连续的,而是离散的。因此,洛伦兹对称性在非常高的能量下被破坏。本文研究了由洛伦兹不变性破坏(LIV)引起的中微子振荡模式,并与由中微子质量引起的正常中微子振荡模式进行了比较。我们发现,在很高的能量下,中微子振荡模式与正常的模式有很大的不同。这为从宇宙学距离测量甚高能量中微子的振荡模式来研究洛伦兹不变性破坏提供了可能。

英文摘要:

Due to quantum gravity fluctuations at the Planck scale, the space-time manifold is no longer continuous, but discretized. As a result the Lorentz symmetry is broken at very high energies. In this article, we study the neutrino oscillation pattern due to the Lorentz Invariance Violation (LIV), and compare it with the normal neutrino oscillation pattern due to neutrino masses. We find that at very high energies, neutrino oscillation pattern is very different from the normal one. This could provide an possibility to study the Lorentz Invariance Violation by measuring the oscillation pattern of very high energy neutrinos from a cosmological distance.
