DESCRIPTION:At large number of colours\, a confining gauge theory becomes 
 a theory\nof weakly interacting hadrons\, with mesons forming a closed sub
 sector.\nIn this context\, constraining the masses and couplings of mesons
  is a\nwell-defined and tractable bootstrap problem. In my talk\, I will\n
 review the EFT bootstrap and show how it applies to meson scattering.\nSpe
 cifically\, I will explain how a few simple but carefully chosen\nassumpti
 ons lead us to an extremal amplitude featuring a Regge\ntrajectory with me
 sons at all spins\, and numerical data remarkably\nclose to real-world QCD
