SUMMARY:QCD Form Factors from Large N Chiral Algebras - Roland Bittleston

DESCRIPTION:The collinear singularities of form factors in certain self-du
 al QCDs determine an abstract chiral algebra. &nbsp\;In this talk I will r
 ealize an example concretely as the large N limit of an algebra of operato
 rs living on a 2d holomorphic surface defect. &nbsp\;The construction goes
  via twisted holography for the type I topological string on a Calabi-Yau 
 5-fold related to twistor space. &nbsp\;I will explain how this realizatio
 n can be exploited to compute QCD form factors in flat space\, and helicit
 y amplitudes on a range of self-dual backgrounds. &nbsp\;This is joint wor
 k with Kevin Costello and Keyou Zeng.
