  We investigate brane world models in higher-derivative gravity theories where
the gravitational Lagrangian is an arbitrary function of the Ricci scalar.
Making use of the conformal equivalence of such gravity models and
Einstein-Hilbert gravity with a scalar field, we deduce the main features of
higher-derivative gravity brane worlds. We solve for a gravity model that has
corrections quadratic in the Ricci scalar and show one can evade both
fine-tuning and the need for a bulk cosmological constant. An analysis of
tensor and scalar perturbations shows gravity is localized on the brane and we
recover the Newtonian limit.
