Lepton flavor violation and leptogenesis in discrete flavor symmetric scotogenic model

TL;DR: In this article, the scotogenic model proposed by Ma was realised by using discrete symmetries, in which the non-zero mass of light neutrinos was obtained by assuming a non-degeneracy in the loop factor.

Abstract: 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, the 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 $l_{\alpha}\longrightarrow l_{\beta}\gamma$ and $l_{\alpha}\longrightarrow 3l_{\beta}$, 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.
