  In large extra dimension models the presence of an interaction between the
Ricci scalar curvature and the Higgs doublet of the Standard Model can give
rise to an invisible decay of the Higgs to Kaluza Klein graviscalars. The
corresponding invisible width can cause a suppression of the LHC rates of a
light Higgs in the visible channels below 5 sigma in some regions of the
parameter space of the model. However in such regions the Higgs can be
discovered through its invisible decay. The combination of the measurements
done at the LHC and the LC can determine to some accuracy the parameters of the
model.
