普朗克尺度效应引起的中微子混合和磁矩

Neutrino mixings and magnetic moments due to Planck scale effects

Bipin Singh Koranga

摘要:

本文考虑了普朗克标度算符对中微子磁矩的影响。我们假设中微子质量和混合的主要部分是通过大统一尺度算符产生的。我们进一步假设,额外的离散对称性使中微子混合双峰。量子引力(普朗克尺度)效应导致一个有效的$SU(2)_{L}\times U(1)$不变维5拉格朗日中微子和希格斯场,这引起了额外的条款,中微子质量矩阵。这些附加项可以被认为是大统一尺度双极大中微子质量矩阵的微扰。我们假设引力相互作用是味盲的,我们研究了中微子混合和磁矩由于以上的大统一尺度的物理。

英文摘要:

In this paper, we consider the effect of Planck scale operators on neutrino magnetic moments. We assume that the main part of neutrino masses and mixings arise through GUT scale operators. We further assume that additional discrete symmetries make the neutrino mixing bi-maximal. Quantum gravitational (Planck scale) effects lead to an effective $SU(2)_{L}\times U(1)$ invariant dimension-5 Lagrangian involving neutrino and Higgs fields, which gives rise to additional terms in neutrino mass matrix. These additional terms can be considered to be perturbation of the GUT scale bi-maximal neutrino mass matrix. We assume that the gravitational interaction is flavour blind and we study the neutrino mixings and magnetic moments due to the physics above the GUT scale.
