  Bloch branes were introduced previously and are constructed in a system
described by two real scalar fields coupled with gravity in (4, 1) dimensions
in warped spacetime involving one extra dimension. This work investigates
gravity on such thick branes with internal structure and focuses on the effects
of massive graviton modes localization on the brane and to what extent they
might reproduce the 4d gravity at a scale before escaping into the extra
dimension. In this way gravitational measurements on the brane could reveal the
existence of the extra dimension on some scales, with possible applications on
brane cosmology.
