论文摘要
我们研究了相对右手中微子的情况下，在最小的左右对称模型中，我们研究了中微子双β（$0νβ$）的衰减速率。通过使用有效的现场理论方法，我们系统地将所有贡献包括在模型中，以及衰减幅度对右手中微子质量的依赖性。在I型和II型Seesaw方案中，我们分析了右撇子中微子比大约10 MEV重的影响，这表明这种效果在下一代实验中即使是正常的层次结构，也可以在下一代实验中检测到$0νβ$衰变，即使是针对正常的层次结构，并且由相对较大的右手尺度设置为大量假设的右手级别的右手级别的Bosons。最后，我们评论光右中微子和强大的CP问题之间的可能联系。
We investigate neutrinoless double beta ($0νββ$) decay rates in minimal left-right symmetric models in presence of relatively light right-handed neutrinos. By use of an effective field theory approach, we systematically include all contributions in the model as well as the dependence of the decay amplitude on the masses of right-handed neutrinos. In type-I and type-II seesaw scenarios, we analyze the impact of right-handed neutrinos heavier than about 10 MeV, showing that this effect can lead to a detection of $0νββ$ decay in the next-generation experiments even for the normal hierarchy and a relatively large right-handed scale set by the mass of hypothetical right-handed gauge bosons. Finally, we comment on a possible connection between light right-handed neutrinos and the strong CP problem.
