Dual EFT Bootstrap: QCD flux tubes
Joan Elias Miró, Andrea Guerrieri
We develop a bootstrap approach to Effective Field Theories (EFTs) based on the concept of duality in optimisation theory. As a first application, we consider the fascinating set o…
Where is String Theory?
Andrea Guerrieri, Joao Penedones, Pedro Vieira
We use the S-matrix bootstrap to carve out the space of unitary, crossing symmetric and supersymmetric graviton scattering amplitudes in ten dimensions. We focus on the leading Wil…
S-matrix Bootstrap for Effective Field Theories: Massless Pions
Andrea Guerrieri, Joao Penedones, Pedro Vieira
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 pion…
Dual S-matrix Bootstrap I: 2D Theory
Andrea L Guerrieri, Alexandre Homrich, Pedro Vieira
Using duality in optimization theory we formulate a dual approach to the S-matrix bootstrap that provides rigorous bounds to 2D QFT observables as a consequence of unitarity, cross…
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…
Bootstrapping QCD: the Lake, the Peninsula and the Kink
Andrea L. Guerrieri, Joao Penedones, Pedro Vieira
We consider the S-matrix bootstrap of four dimensional scattering amplitudes with symmetry and no bound-states. We explore the allowed space of scattering lengths which para…
