Abstract
We study a two scalar inert doublet model (IDMS3) which is stabilized by an S3 symmetry considering two scenarios: (a) two of the scalars in each charged sector are mass degenerated due to a residual symmetry, (b) there is no mass degeneracy because of the introduction of soft terms that break the symmetry. A major difference between this model and the one with only one inert Higgs doublet (IDM) is that it has twice the number of possible dark matter (DM) candidates. In particular we show that for the case (a) it is possible to have two CP even DM candidates. Besides, in case (b) the upper limit to the intermediate mass region for the one IDM in our model is larger, once we obtain a DM candidate with mass equals to 257 GeV.
