Query: Is the radion a bulk Higgs doublet?   In 2013, Geller, Bar-Shalom and Soni (GBS) proposed a Randall-Sundrum model
with a bulk SU(2) doublet. They found that the doublet could both stabilize the
extra dimension and break the electroweak symmetry; the radion and the Higgs
boson were then one and the same. This alternative to the Goldberger-Wise
mechanism contained enhanced Higgs couplings to gluons and photons, but at the
time of the GBS paper, these couplings were phenomenologically acceptable. We
note that updated results from the LHC rule out the model as presented. One can
expand the parameter space by extending the model to include bulk fermions. We
do so, and show that for any choice of parameters, the model remains in
conflict with LHC data. We then extend the scalar sector to a two Higgs model,
and show that the model contains a phenomenologically unacceptable zero mass
scalar. This property will likely apply to all extensions to the scalar sector,
and thus we conclude that the radion cannot be part of a bulk doublet.
