Positivity constraints on interacting spin-2 fields

Positivity constraints on interacting spin-2 fields

Abstract The consistency of the EFT of two interacting spin-2 fields is checked by applying forward limit positivity bounds on the scattering amplitudes to exclude the region of parameter space devoid of a standard UV completion. We focus on two classes of theories that have the highest possible EFT...
