Abstract: We consider a five dimensional DGP-brane scenario endowed with anon-minimally coupled scalar field within the context of Brans-Dicke theory.This theory predicts that the mass appearing in the gravitational potential ismodified by the addition of the mass of the effective intrinsic curvature onthe brane. We also derive the effective four dimensional field equations on a3+1 dimensional brane where the fifth dimension is assumed to have an orbifoldsymmetry. Finally, we discuss the cosmological implications of this setup,predicting an accelerated expanding universe with a value of the Brans-Dickeparameter $\omega$ consistent with values resulting from the solar systemobservations.
