II型跷跷板轻子发生的轻子味破坏实验

Lepton Flavour Violation Tests of Type II Seesaw Leptogenesis

N. D. Barrie, S. T. Petcov

摘要:

即将到来的轻子味违反实验寻找$μ\rightarrow 3e$和$μ$到$ e $转换的核过程将提供新的机会来测试中微子部门的基本属性,并可能的物质的起源。在最近的研究中,发现II型跷跷板机制可以同时解释中微子质量、轻子生成和暴胀。该模型的一个关键预测是轻子味破坏衰变产生信号的可能性。未来的实验,如Mu3e和COMET将是确定相关三重态希格斯粒子的性质不可或缺的,并将补充其他地面实验搜索和宇宙学测量。在这项工作中,我们调查的成分的第二类跷跷板Leptogenesis方案的检测前景,并讨论了相应的中微子振荡参数和$\mathcal{CP}$阶段的依赖关系。

英文摘要:

Upcoming Lepton Flavour Violation experiments searching for $μ\rightarrow 3e$ and $μ$ to $ e $ conversion in nuclei processes will provide new opportunities to test the fundamental properties of the neutrino sector, and possibly the origin of matter. In recent work, it was shown that the Type II Seesaw mechanism alone can simultaneously explain the neutrino masses, Leptogenesis, and inflation. A key prediction of this model was the possibility of signals being produced in Lepton Flavour Violation decays. Searches at future experiments such as Mu3e and COMET will be integral to determining the properties of the associated triplet Higgs, and will complement other terrestrial experimental searches and cosmological measurements. In this work, we survey the detection prospects for the ingredients of the Type II Seesaw Leptogenesis scenario, and discuss the corresponding dependencies on the neutrino oscillation parameters and $\mathcal{CP}$ phases.
