DESCRIPTION:Eliot Hijano\nA holographic understanding of physics in flat s
 pace is currently lacking. In this talk\, I will explore the flat limit of
  AdS/CFT to provide flat space with an indirect\, holographic framework. 
 The observables of physics in flat space are S-matrix elements and can 
 be obtained from a large AdS-radius limit of certain CFT correlators. I wi
 ll present a method for constructing CFT operators which create incoming 
 and outgoing scattering states in flat space. Using this method\, I will o
 btain explicit expressions for incoming and outgoing U(1) gauge fields. W
 einberg soft photon theorems then follow from Ward identities of conserve
 d CFT currents\, providing a link between CFT physics and the IR physics o
 f flat space-times.\n
