We consider an extension of the standard model with three Higgs doublet model and $S_3times mathbb{Z}_2$ discrete symmetries. Two of the scalar doublets are inert due to the $mathbb{Z}_2$ symmetry. We have calculated all the mass spectra in the scalar and lepton sectors and accommodated the leptonic mixing matrix as well. We also show that the model has scalar and pseudoscalar candidates to dark matter. Constraints on the parameters of the model coming from the decay $muto egamma$ were considered and we found signals between the current and the upcoming experimental limits, and from that decay we can predict the one-loop $muto eebar{e}$ channel.
We present a scotogenic model, i.e. a one-loop neutrino mass model with dark right-handed neutrino gauge singlets and one inert dark scalar gauge doublet $eta$, which has symmetries that lead to co-bimaximal mixing, i.e. to an atmospheric mixing angl
We propose a leptoquark model with two scalar leptoquarks $S^{}_1 left( bar{3},1,frac{1}{3} right)$ and $widetilde{R}^{}_2 left(3,2,frac{1}{6} right)$ to give a combined explanation of neutrino masses, lepton flavor mixing and the anomaly of muon $g-
We study the dark matter phenomenology of scotogenic frameworks through the rather illustrative model T1-2A extending the Standard Model by scalar and fermionic singlets and doublets. Such a setup is phenomenologically attractive since it provides th
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
We consider trimaximal lepton mixing, defined by |U_{alpha 2}|^2 = 1/3 for all alpha = e, mu, tau. This corresponds to a two-parameter lepton mixing matrix U. We present a model for the lepton sector in which trimaximal mixing is enforced by softly b
