DESCRIPTION:Speakers: Roger Morales\n\n\nIn this talk\, I will study the s
 pace of planar\, maximally supersymmetric EFTs that reduce to N=4 super Ya
 ng-Mills theory at low energies. I will show that consistency under supers
 ymmetry and tree-level factorization\, together with a parity condition on
  the scalar amplitudes\, requires the Wilson coefficients of the 4-point a
 mplitude to obey novel nonlinear constraints. When these constraints are c
 ombined with positivity\, the allowed values of the 4-point Wilson coeffic
 ients converge towards the Veneziano amplitude\, finding open superstring 
 theory as the unique answer. More broadly\, our results show that higher-p
 oint amplitudes can provide new constraints on the EFT data\, and that the
  space of consistent quantum field theories might be much smaller than pre
 viously suggested by a simple four-point analysis.\n\n \n\nhttps://indico
