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 Z2 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.
