Description
In a minimal singlet extension of the MSSM, the nMSSM, both the problem of
baryogenesis and dark matter can be elegantly solved without large fine-tuning. As a
result of these cosmological constraints, the parameter space of the nMSSM is
strongly reduced, and the model predicts that a number of new Higgs and
supersymmetric particles are within reach of the LHC and ILC. Here the collider
phenomenology at the LHC and ILC is analyzed in detail. It is shown that the LHC
could make discoveries of sereval new particles, while precision measurements at the
ILC would allow to test the role of the nMSSM for the origin of baryonic matter and
dark matter. Also prospects for dark matter direct detection and searches for the
electron electric dipole moment are presented.
