Title:The curious properties of scattering amplitudes in certain quantum field theories
Seminar:GAP Seminar
Speaker:Radu Roiban, Penn State Physics
Abstract:
I will begin by briefly reviewing the perturbative construction of scattering amplitudes in general gauge theories and then discuss some of their unexpected properties: a relation between their momentum dependence and their group theory structure, a momentum space conformal symmetry. If time allows, I will also comment on the result of the evaluation of momentum integrals. An all-order proof and a fundamental understanding of these properties are currently open questions.
