We perform a one‐loop test of the holographic interpretation of the Karch‐Randall model, whereby a massive graviton appears on an AdS4brane in an AdS5bulk. Within the AdS/CFT framework, we examine the quantum corrections to the graviton propagator on the brane, and demonstrate that they induce a graviton mass in exact agreement with the Karch‐Randall result. Interestingly enough, at one loop order, the spin 0, spin 1/2 and spin 1 loops contribute to the dynamically generated (mass)2in the same 1 : 3 : 12 ratio as enters the Weyl anomaly and the 1/r3corrections to the Newtonian gravitational potential. © 2003 American Institute of Physics
