Tracking S-matrix bounds across dimensions
Mehmet Asim Gumus, Simon Metayer, Piotr Tourkine
We study massive scattering of identical scalar particles in spacetime dimensions 3 to 11 using non-perturbative S-matrix bootstrap techniques. Treating as a continuo…

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…
