摘要

我们研究了一种基于风味对称的扩展左右对称模型(LRSM)，该模型具有显性ii型跷跷板机制，并探索了相关的中微子现象学。该模型的粒子含量包括通常的夸克和轻子以及费米子扇区中每一代额外的不育费米子，而标量含量包括希格斯双重态和标量双重态。这种LRSM的扩展是通过使用$A_{4}\乘以$ Z_{4}$的离散对称性来实现的。在这项工作中，我们在框架内纳入了无菌中微子暗物质(DM)现象学和无中微子双β衰变的研究。

Neutrinoless double beta decay and sterile neutrino dark matter in extended left right symmetric model

We have studied a flavor symmetry-based extended left-right symmetric model(LRSM) with a dominant type-II seesaw mechanism and have explored the associated neutrino phenomenology. The particle content of the model includes usual quarks and leptons along with additional sterile fermion per generation in the fermion sector while the scalar content contains Higgs doublets and scalar bidoublet. This extension of LRSM has been realized by using $A_{4}\times Z_{4}$ discrete symmetries. In this work, we have included the study of sterile neutrino dark matter(DM) phenomenology and neutrinoless double beta decay within the framework.
