- Abstract
Abstract: 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 η, which has symmetries that lead to co-bimaximal mixing, i.e. to an atmospheric mixing angle θ
23 = 45° and to a CP -violating phase δ = ±π/2, while the mixing angle θ
13 remains arbitrary. The symmetries consist of softly broken lepton numbers L
α (α = e, μ, τ), a non-standard CP symmetry, and three ℤ
2 symmetries. We indicate two possibilities for extending the model to the quark sector. Since the model has, besides η, three scalar gauge doublets, we perform a thorough discussion of its scalar sector. We demonstrate that it can accommodate a Standard Model-like scalar with mass 125 GeV, with all the other charged and neutral scalars having much higher masses.
