ITMP Seminar "Scattering in chiral strong backgrounds"

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.
