Gravity in the Randall-Sundrum two D-brane model

We analyze the Randall-Sundrum two D-brane model by linear perturbation and then consider the linearized gravity on the D brane. The qualitative contribution from the Kaluza-Klein modes of gauge fields to the coupling to the gravity on the brane will be addressed. As a consequence, the gauge fields localized on the brane are shown not to contribute to the gravity on the brane at large distances. Although the coupling between gauge fields and gravity appears in the next order, the ordinary coupling cannot be realized
