  In the context of warped extra-dimensional models with all fields propagating
in the bulk, we address the phenomenology of a bulk scalar Higgs boson, and
calculate its production cross section at the LHC as well as its tree-level
effects on mediating flavor changing neutral currents. We perform the
calculations based on two different approaches. First, we compute our
predictions analytically by considering all the degrees of freedom emerging
from the dimensional reduction (the infinite tower of Kaluza Klein modes (KK)).
In the second approach, we perform our calculations numerically by considering
only the effects caused by the first few KK modes, present in the 4-dimensional
effective theory. In the case of a Higgs leaking far from the brane, both
approaches give the same predictions as the effects of the heavier KK modes
decouple. However, as the Higgs boson is pushed towards the TeV brane, the two
approaches seem to be equivalent only when one includes heavier and heavier
degrees of freedom (which do not seem to decouple). To reconcile these results
it is necessary to introduce a type of higher derivative operator which
essentially encodes the effects of integrating out the heavy KK modes and
dresses the brane Higgs so that it looks just like a bulk Higgs.
