INSTITUTE FOR THEORETICAL AND MATHEMATICAL PHYSICS

ITMP Seminar "Scattering in chiral strong backgrounds"

ITMP Seminar
23 November 2020

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 25, at 18:00 (Moscow time). The seminar will be arranged via Zoom.

 

Speaker: Dr. Tim Adamo, University of Edinburgh

Title: Scattering in chiral strong backgrounds

Abstract: There are many reasons to be interested in quantum field theory in the presence of strong, non-perturbative background fields, but surprisingly little is known in these scenarios, especially when compared to trivial backgrounds. For instance, the full semi-classical S-matrices of gauge theory and gravity are known in a trivial background, but even for simple strong backgrounds the tree-level amplitudes of these theories have not been computed beyond four-external particles. This raises the question: are all-multiplicity formulae (and other hallmarks of the study of scattering amplitudes in recent years) inextricably tied to trivial backgrounds? In this talk, I will demonstrate that for a broad class of chiral backgrounds in four-dimensions, we can find all-multiplicity expressions for tree-level scattering amplitudes of gauge theory and gravity which are remarkably simple and clearly un-related to standard background-coupled field theory on space-time. 

 

If you want to join the seminar please register here before 14:00, November 25.
