%X We identify the effective theory appropriate to the propagation of
massless bulk fields in brane-world scenarios, to show that the dominant
low-energy effect of asymmetric warping in the bulk is to modify
the dispersion relation of the effective 4-dimensional modes. We
show how such changes to the graviton dispersion relation may be
bounded through the effects they imply, through loops, for the propagation
of standard model particles. We compute these bounds and show that
they provide, in some cases, the strongest constraints on nonstandard
gravitational dispersions. The bounds obtained in this way are the
strongest for the fewest extra dimensions and when the extra-dimensional
Planck mass is the smallest. Although the best bounds come for warped
5-D scenarios, for which M5 is O(TeV), even in 4 dimensions the graviton
loop can lead to a bound on the graviton speed which is comparable
with other constraints. © SISSA/ISAS 2002.
