S-matrix Bootstrap for Effective Field Theories: Massless Pions (2011.02802v1)
Published 5 Nov 2020 in hep-th
Abstract: We use the numerical S-matrix bootstrap method to obtain bounds on the two leading Wilson coefficients of the chiral lagrangian controlling the low-energy dynamics of massless pions thus providing a proof of concept that the numerical S-matrix bootstrap can be used to derive non-perturbative bounds on EFTs in more than two spacetime dimensions.
