论文摘要
我们通过研究违反带电的Lepton风味衰减的新物理学贡献的新物理学贡献，在违反中微子的差异和中性betaβ衰减中，在正常的层次结构和倒置的层次结构中，我们在绝对尺度上得出了最低限制。中微子质量是在模型中通过II型SEESAW占优势产生的，借助于沉重的无菌中微子。这种情况允许大型轻质的中微子混合，混合促进了中微子双β衰变和违反Lepton风味的新频道。我们以振荡参数来表达所有模型参数，以限制光中微子质量尺度并提取有关中微子质量层次结构的信息。
We derive the lower bound on absolute scale of lightest neutrino mass for normal hierarchy and inverted hierarchy pattern of light neutrinos by studying the new physics contributions to charged lepton flavour violating decays and neutrinoless double beta decay in the framework of a TeV scale left-right symmetric model. Neutrino mass is generated in the model via type-II seesaw dominance with the help of a heavy sterile neutrino. This scenario allows large light-heavy neutrino mixing and the mixing facilitates new channels for neutrinoless double beta decay and lepton flavour violating decays. We express all the model parameters in terms of oscillation parameters in order to constrain light neutrino mass scale and extract information on neutrino mass hierarchy.
