Description
General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We revisit a 2HDM where neutrino masses are generated via type I seesaw and propose an extension where neutrino masses are generated via a type II seesaw mechanism and flavor changing interactions are absent via the presence of a U(1) gauge symmetry. After considering a variety of bounds such those rising from higgs, collider physics and electroweak precision we show that our model stands as an interesting extension of the general Two-Higgs-Doublet Model. Possible dark matter realizations are also discussed.
