Constraining Glueball Couplings
Andrea L. Guerrieri, Aditya Hebbar, Balt C. van Rees
We set up a numerical S-matrix bootstrap problem to rigorously constrain bound state couplings given by the residues of poles in elastic amplitudes. We extract upper bounds on thes…
Bounds on photon scattering
Kelian Häring, Aditya Hebbar, Denis Karateev +2
We study 2-to-2 scattering amplitudes of massless spin one particles in space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilso…
Spinning S-matrix Bootstrap in 4d
Aditya Hebbar, Denis Karateev, Joao Penedones
We review unitarity and crossing constraints on scattering amplitudes for particles with spin in four dimensional quantum field theories. As an application we study two to two scat…
Flux Tube S-matrix Bootstrap
Joan Elias Miro, Andrea L. Guerrieri, Aditya Hebbar +2
We bootstrap the S-matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S-matrices is strongl…
