轻子最小味破坏势

On the Potential of Leptonic Minimal Flavour Violation

R. Alonso, M. B. Gavela, D. Hernández, L. Merlo

摘要:

由于马约拉纳中微子质量项的可能性,轻子扇区中的最小味违反可以通过几种方式实现。对于最简单的只有两个右手中微子的See-Saw模型,我们导出了背景值为汤川耦合的场的标量势,并探索了它的最小值。马约拉纳性质发挥着独特的作用:与最简单的夸克情况相反,最小势允许大混合角,并预测最大马约拉纳相。这反过来又指出了中微子质量等级和混合模式之间的强相关性。

英文摘要:

Minimal Flavour Violation can be realized in several ways in the lepton sector due to the possibility of Majorana neutrino mass terms. We derive the scalar potential for the fields whose background values are the Yukawa couplings, for the simplest See-Saw model with just two right-handed neutrinos, and explore its minima. The Majorana character plays a distinctive role: the minimum of the potential allows for large mixing angles -in contrast to the simplest quark case- and predicts a maximal Majorana phase. This points in turn to a strong correlation between neutrino mass hierarchy and mixing pattern.
