We have studied the scotogenic model proposed by Ernest Ma, which is an extension of the Standard Model by three singlet right handed neutrinos and a scalar doublet. This model proposes that the light neutrinos acquire a non-zero mass at 1-loop level. In this work, realisation of the scotogenic model is done by using discrete symmetries $A_4\times Z_4$ in which the non-zero ${\theta }_{13}$ is produced by assuming a non-degeneracy in the loop factor. Considering different lepton flavor violating (LFV) processes such as $l_{\alpha }⟶l_{\beta }\gamma$ and $l_{\alpha }⟶3l_{\beta }$, their impact on neutrino phenomenology is studied. We have also analysed $0\nu \beta \beta$ and baryon asymmetry of the Universe (BAU) in this work.

我们研究了 Ernest Ma 提出的 scotogenic 模型，它是标准模型的扩展，由三个单线态右手中微子和一个标量双线态。该模型建议轻中微子在 1 环水平上获得非零质量。在这项工作中，通过使用离散对称性来实现 scotogenic 模型${\mathrm{一种}}_4\times Z_4$ 其中非零 ${\theta }_{13}$是通过假设循环因子的非简并性产生的。考虑到不同的轻子风味违反 (LFV) 过程，例如${升}_{\alpha }⟶{升}_{\beta }\gamma$ 和 ${升}_{\alpha }⟶3{升}_{\beta }$，研究它们对中微子现象学的影响。我们还分析了$0\nu \beta \beta$ 和宇宙重子不对称性 (BAU) 在这项工作中。
