Mon, Oct 14, 2019, 12:30 pm

Abstract: It is currently not well understood whether the holographic principle can be applied to asymptotically flat space-times. This talk will consider a flat limit of AdS/CFT that leads to a formula relating S-matrix amplitudes in flat space and conformal correlators in AdS/CFT. I will explain how to use the formula to compute S-matrices in simple examples, and I will discuss how to recast flat space physics concepts in the language of conformal field theory and holography. I will also discuss IR divergences and the construction of an IR finite S-matrix using AdS/CFT.
