Description
We present a first complete calculation of scattering amplitudes of massive spin-2 Kaluza Klein resonances in extra dimensional theories. Although individual contributions of Kaluza-Klein particle scattering can grow as fast as $E^{10}$, intricate cancellations ensure that the full scattering amplitudes grow only as fast as $E^2$. We provide the necessary sum-rules that ensure such cancellations and describe the anatomy of these scattering amplitudes in both flat-toroidal as well as warped models in Anti-De-Sitter space. We contrast this calculation with theories of massive gravity and its extensions.
