Regge trajectories for UV completions of graviton scattering from polynomial boundedness
Christopher Eckner, Felipe Figueroa, Simon Metayer +1
We study graviton scattering amplitudes. Assuming they are UV completed by a theory of weakly coupled massive higher spins, we demonstrate that the UV completion must possess infin…

On the number of Regge trajectories for dual amplitudes
Christopher Eckner, Felipe Figueroa, Piotr Tourkine
Regge poles connect the analytic structure of scattering amplitudes, analytically continued in spin, to the high-energy limit in momentum space. Dual models are expected to have on…
