SUMMARY:Progress on long-distance singularities in gauge theory scattering
  amplitudes - Einan Gardi\, University of Edinburgh
DTSTART:20140520T140000Z

CONTACT:Ben Gripaios
DESCRIPTION:I will report on the on-going computation the soft anomalous d
 imension in multi-leg gauge-theory scattering amplitudes at the three-loop
 s order. I will also discuss the non-Abelian exponentiation theorem and it
 s recent generalisation to multiple Wilson lines\, and illustrate how diag
 rammatic exponentiation becomes useful in the course evaluating the soft a
 nomalous dimension and understanding its analytic structure.
