Unparticle behavior is shown to be realized in the Randall-Sundrum 2 RS 2 and the Lykken-Randall LR brane scenarios when brane-localized Standard Model currents are coupled to a massive vector field living in the five-dimensional warped background of the RS 2 model. By the AdS-CFT dictionary these backgrounds exhibit certain properties of the unparticle CFT at large N c and strong t Hooft coupling. Within the RS 2 model we also examine and contrast in detail the scalar and vector position-space correlators at intermediate and large distances. Unitarity of brane-to-brane scattering amplitudes is seen to imply a necessary and sufficient condition on the positivity of the bulk mass, which leads to the well-known unitarity bound on vector operators in a CFT.
