SUMMARY:Scattering in Field Theory - Louise Dolan (University of North Car
 olina)
DTSTART:20250925T150000Z
DTEND:20250925T154500Z
UID:TALK235030@talks.cam.ac.uk
DESCRIPTION:The scattering polynomials leading to the Cachazo-He-Yuan repr
 esentation of tree level amplitudes are described both on and off shell\, 
 and for individual graphs. The proof these non-Lagrangian amplitudes corre
 spond to conventional gauge field theory scattering uses a recurrence rela
 tion\, and the conformal Yangian provides symmetry.&nbsp\;
