DESCRIPTION:Speakers: Elisabetta Armanini (EPFL)\n\nSéminaire Amplitudes 
 et Gravitation sur l'Yvette (IHES/IPhT)\nWe study scattering on the Coulom
 b branch of planar N=4 SYM.  At weak 't Hooft coupling scattering amplitu
 des can be computed using Feynman diagrams and the relevant degrees of fre
 edom are quarks and gluons. At strong 't Hooft coupling the dynamics is ca
 ptured by string scattering in flat space.  Dual conformal symmetry makes
  it possible to constrain the unitarity properties and the spectrum of the
  amplitude: bound states are encoded in the cusp anomalous dimension of a 
 Maldacena-Wilson line with operators inserted at the cusp\, which is fixed
  by integrability.  In this talk\, we show how to combine dual conformal 
 invariance\, integrability\, worldsheet bootstrap and the S-matrix bootstr
 ap to explore scattering at finite 't Hooft coupling.  [Based on 2510.199
