DESCRIPTION:Title: Celestial holography and twistors\n\nAbstract:The celest
 ial holography program aims to describe scattering amplitudes of gauge the
 ory and gravity in terms of a conformal field theory living on the celesti
 al sphere.  I will explain an approach to celestial holography based on tw
 istors\, which recasts it in a formulation much closer to ordinary hologra
 phy.  I will also discuss the role of gauge anomalies on twistor space\, a
 nd a Green-Schwarz mechanism\, in celestial holography at loop-level. This
  is joint with Natalie Paquette.\n\nSeminar Physique Mathématique\n	En lign
