Description
Scattering Amplitudes are crucial to understanding the range of validity of effective field theories. In this talk I will talk about the unitarity and validity of extra dimensional gravity and demonstrate that the Goldstone Boson Equivalence Theorem ensures that high energy scattering of massive Kaluza-Klein states are unitary through a series of Ward Identities. Furthermore I will show that the Goldstone Boson Equivalence theorem can be used to demonstrate gauge and gravity double copy in extra dimensions.
