Query: Conformal matter in warped backgrounds   Warped backgrounds in five dimensional models can provide solutions to
various hierarchy problems in particle physics if the standard model matter is
associated with the zero modes of bulk fields with nontrivial profiles along
the extra dimension. We investigate the case of a {\sl conformally} coupled
massless scalar. This field possesses a zero mode whose action density is
exponentially enhanced along the transverse direction in a warped background,
{\em i.e.} near the negative tension brane in the RS setting. At the zero mode
level effective 5D composites of this scalar and its derivatives, which are
suppressed by powers of the fundamental gravitational scale, yield 4D
interactions of electroweak strength. This suggests a certain importance of
conformally coupled scalar fields for extra-dimensional model building.
