  We consider a quartic interaction of the Higgs and Goldberger-Wise fields,
which connects the mechanism of the extra dimension size stabilization with
spontaneous symmetry breaking on our brane and gives rise to a coupling of the
Higgs field to the radion and its KK tower. We estimate a possible influence of
this coupling on the Higgs-radion mixing and study restrictions on model
parameters from the LHC data.
