准简并中微子质谱有限量子修正的大θ_13

Large θ_13 from finite quantum corrections in quasi-degenerate neutrino mass spectrum

Takeshi Araki, Chao-Qiang Geng

摘要:

我们研究了几种著名中微子混合矩阵的有限量子修正,发现T2K和MINOS最近报道的大θ 13值很难用有限量子修正来解释。为了很好地再现所有实验上有利的中微子混合角和质量,我们提出了一个新的中微子混合模式。我们还通过对标准模型的稍微扩展来演示一个简单的实现来说明量子修正。

英文摘要:

We study finite quantum corrections for several well known neutrino mixing matrices and find that it is hard to account for the large value of θ_13 recently reported by T2K and MINOS. To nicely reproduce all experimentally favored neutrino mixing angles and masses, we propose a new neutrino mixing pattern. We also demonstrate a simple realization by slightly extending the standard model to illustrate the quantum corrections.
