EFT anomalous dimensions from the S-matrix
Joan Elias Miró, James Ingoldby, Marc Riembau
We use the on-shell S-matrix and form factors to compute anomalous dimensions of higher dimension operators in the Standard Model Effective Field Theory. We find that in many insta…

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…

S-matrix bootstrap for resonances
N. Doroud, J. Elias Miró
We study the -matrix element of a generic, gapped and Lorentz invariant QFT in space time dimensions. We derive an analytical bound on the coupling of th…
