Maths HEP Lunchtime Seminars: Symmetries and Integrability of Scattering Amplitudes in N=4 super Yang-Mills Theory

Presented by Jan Plefka, Humboldt University Berlin

12 February 2010 13:00 in CM221

In the recent years the discovery of integrable structures in N=4
super Yang-Mills has enlarged our understanding of this fascinating
most symmetric four dimensional gauge theory tremendously. Thus far
these exact results concern the computation of anomalous scaling
dimensions of gauge invariant operators. In this talk we will discuss
how integrable structures manifest themselves in the study of
scattering amplitudes. In particular the invariance of tree-level
amplitudes under an infinite dimensional Yangian symmetry will be
reported. Finally we discuss a new Higgs regularization scheme which
preserves an extended dual conformal invariance at loop level.
