普朗克尺度效应下四味混合大气混合角$θ_{23}$的大变化

Large Changes of Atmospheric Mixing Angle $θ_{23}$ with Four Flavor Mixing from Planck Scale Effects

Bipin Singh Koranga, Vivek Kumar Nautiyal

摘要:

本文研究了普朗克尺度对四味中微子混合的影响。在$M_{x}=M_{\rm planck}$处的引力相互作用,我们发现对于退化的神经元质量序,普朗克尺度效应改变了混合角$θ'_{23}$,$θ'_{12}$值和$θ'_{13}$,$θ'_{14}$,$θ'_{34}$,$θ'_{24}$在GUT尺度以上不变。本文研究了GUT标度以上四种味中微子的混合。

英文摘要:

We consider the effects of Planck scale on four flavour neutrino mixings. The gravational interaction at $M_{x}=M_{\rm planck}$, we find that for degenerate neurino mass order, the Planck scale effects changes the mixing angle $θ'_{23}$, $θ'_{12}$ values and $θ'_{13}$, $θ'_{14}$, $θ'_{34}$, $θ'_{24}$ are unchanged above the GUT scale. In this paper, we study neutrino mixing in four flavor above the GUT scale.
