具有约束序列优势的约束MSSM中的轻子味破坏

Lepton Flavour Violation in the Constrained MSSM with Constrained Sequential Dominance

Stefan Antusch, Steve F. King

摘要:

我们考虑了约束最小超对称标准模型中的带电轻子味违反(LFV),扩展到包含约束顺序占优(CSD)的跷跷板机制,其中CSD提供了一个自然的跷跷板解释三双峰中微子混合.当三双峰中微子混合的带电轻子修正包括在内时,我们发现LFV分支比之间的特征相关性,取决于右手中微子的质量排序,与轻子混合角$θ_{13}$(在某些情况下也对狄拉克CP相位$δ$)的显著依赖。

英文摘要:

We consider charged Lepton Flavour Violation (LFV) in the Constrained Minimal Supersymmetric Standard Model, extended to include the see-saw mechanism with Constrained Sequential Dominance (CSD), where CSD provides a natural see-saw explanation of tri-bimaximal neutrino mixing. When charged lepton corrections to tri-bimaximal neutrino mixing are included, we discover characteristic correlations among the LFV branching ratios, depending on the mass ordering of the right-handed neutrinos, with a pronounced dependence on the leptonic mixing angle $θ_{13}$ (and in some cases also on the Dirac CP phase $δ$).
