Query: Multi-Scalar-Singlet Extension of the Standard Model - the Case for Dark
  Matter and an Invisible Higgs Boson   We consider a simple extension of the Standard Model by the addition of N
real scalar gauge singlets $\vp$ that are candidates for Dark Matter. By
collecting theoretical and experimental constraints we determine the space of
allowed parameters of the model. The possibility of ameliorating the little
hierarchy problem within the multi-singlet model is discussed. The
Spergel-Steinhardt solution of the Dark Matter density cusp problem is
revisited. It is shown that fitting the recent CRESST-II data for Dark Matter
nucleus scattering implies that the standard Higgs boson decays predominantly
into pairs of Dark Matter scalars. It that case discovery of the Higgs boson at
LHC and Tevatron is impossible. The most likely mass of the dark scalars is in
the range 15 GeV $\lsim \mvp \lsim$ 50 GeV with $BR(h \to \vp\vp)$ up to 96%.
