Amplitudes and Periods

This workshop will be focused on the recent progress in understanding scattering amplitudes in four-dimensional Yang-Mills theories, such as perturbative quantum chromodynamics (QCD), supersymmetric gauge theories and quantum gravity. A remarkable progress was achieved in our ability to calculate multi-particle scattering amplitudes and anomalous dimensions governing scaling violation of high-energy processes. These are relevant both for phenomenological and theoretical purposes. Many advances have been made possible with the input of new ideas from advanced mathematical concepts such as theory of mixed motives and motivic Galois groups, variations of mixed Hodge structures, Grassmanians, cluster varieties, Yangian symmetries. At the same time, methods of quantum field theory proved to be extremely useful in the study of properties of the multiple zeta values.

The workshop will take place at the Institut des Hautes Études Scientifiques in Bures-sur-Yvette.

Participation in the workshop is open subject only to space constraints. Registration will be obligatory, even for Paris-area scientists, though there are no fees.
