CP violating scalar Dark Matter

We study an extension of the standard model (sm) in which two copies of the sm scalar su(2) doublet which do not acquire a vacuum expectation value (vev), and hence are inert, are added to the scalar sector. we allow for cp-violation in the inert sector, where the lightest inert state is protected from decaying to sm particles through the conservation of a z 2 symmetry. the lightest neutral particle from the inert sector, which has a mixed cp-charge due to cp-violation, is hence a dark matter (dm) candidate. we discuss the new regions of dm relic density opened up by cp-violation, and compare our results to the cp-conserving limit and the inert doublet model (idm). we constrain the parameter space of the cp-violating model using recent results from the large hadron collider (lhc) and dm direct and indirect detection experiments.
