不平衡中微子的双峰混合

Bimaximal mixing from lopsided neutrinos

M. Paraskevas, K. Tamvakis

摘要:

我们认为中微子质量和混合的一般框架内的标准(I型)跷跷板模型导致三个轻中微子的问题。在分层中微子质谱λ^4:λ:1的假设下,与现有数据一致,我们研究了中微子汤川耦合可能的不平衡模式,这些模式可以解释观察到的混合角,包括一个小但非零的混合角|U_{e3}|.还考虑了上述模型在一般SO(10)模型中的嵌入。

英文摘要:

We consider the problem of neutrino masses and mixing within the general framework of standard (type-I) seesaw models leading to three light neutrinos. Under the assumption of a hierarchical neutrino mass spectrum λ^4: λ: 1, consistent with present data, we examine possible lopsided patterns for the neutrino Yukawa couplings that can account for the observed mixing angles, including a small but non-vanishing |U_{e3}|. An embedding of the above within a general class of SO(10) models is also considered.
