Unitarizing scattering amplitudes in theories of compact Extra Dimensions
Scattering amplitudes are paramount to understanding the validity of quantum field theories. In this talk I will discuss scattering amplitudes of massive spin-2 particles. I will contrast the unitarity violating scales of theories of massive gravity and compact extra dimensions. I will also demonstrate how scattering amplitudes in extra dimensions can be obtained via the double copy prescription that relates gauge theory and gravity amplitudes.
