Novel two component dark matter features in the Z2 × Z2 3HDM

Year: 2024

Type: article

Abstract: A bstract We discuss the constraints and phenomenology of the ℤ 2 × ℤ 2 three Higgs doublet model (3HDM) with two inert scalars, originating two dark matter (DM) particles. We elucidate the competing vacua and we submit the model to all theoretical and current experimental constraints. We find unexplored regions of parameter space and investigate their experimental signatures. In particular, we find regions where the two DM particles contribute equally to the relic DM density.
