Description

The 2HDMS is based on the CP-conserving 2HDM extended by a complex singlet
field. We impose an additional Z3 symmetry on the potential. This leads to a
Higgs-sector similar to the Next-to-Minimal Supersymmetric SM (NMSSM),
while having fewer symmetry conditions compared to supersymmetric models. We
introduce the theoretical background of this model and set it up for
phenomenological studies. For this we study theoretical constraints including
tree-level perturbative unitarity,
boundedness from below conditions and vacuum stability constraints.
Furthermore we look at experimental constraints from direct searches for
BSM Higgs bosons at colliders. The impact on the phenomenology of a future linear collider will be incorporated.
