论文摘要
We have studied the correlations among the three absolute neutrino mass observables - the effective Majorana mass ($m_{ee}$) which can be obtained from neutrinoless double beta decay, the electron neutrino mass ($m_β$) which is measured in single beta decay experiments and the sum of the light neutrino masses ($Σ$) which is constrained from cosmological observations, in the context of minimal左右对称模型。已经考虑了两个在现象学上有趣的seesaw优势和II型Seesaw优势的案例。我们已经考虑了来自Lepton风味的独立约束，单个$β$衰减，宇宙学和中微子双β衰减，并确定了将来可以探索的合并允许的参数空间。我们还分析了不同质量变量之间的相关性和紧张关系。此外，还确定了来自Lepton风味的重颗粒的质量以及三个绝对中微子质量可观察物的边界的约束。我们表明，这些约束可以排除对撞机实验未探测的某些参数空间。
We have studied the correlations among the three absolute neutrino mass observables - the effective Majorana mass ($m_{ee}$) which can be obtained from neutrinoless double beta decay, the electron neutrino mass ($m_β$) which is measured in single beta decay experiments and the sum of the light neutrino masses ($Σ$) which is constrained from cosmological observations, in the context of minimal left-right symmetric model. Two phenomenologically interesting cases of type-I seesaw dominance as well as type-II seesaw dominance have been considered. We have taken into account the independent constraints coming from lepton flavor violation, single $β$ decay, cosmology and neutrinoless double beta decay and have determined the combined allowed parameter space that can be probed in the future experiments. We have also analyzed the correlations and tensions between the different mass variables. In addition, the constraints on the masses of the heavy particles coming from lepton flavor violation and the bounds on three absolute neutrino mass observables are also determined. We show that these constraints can rule out some of the parameter space which are not probed by the collider experiments.
