CPT Student Seminar: Four-point Amplitudes and Correlators to Ten Loops Via Simple, Graphical Bootstraps in Planar N = 4 Super-Yang Mills (SYM)

Presented by Vuong-viet Tran, Durham University

26 September 2016 17:00 in OC218

We introduce two new graphical-level relations among possible contributions to the four-point correlation function and scattering amplitude in planar, maximally supersymmetric Yang-Mills theory. When combined with the rung rule, these prove powerful enough to fully determine both functions through ten loops. This then also yields the full five-point amplitude to eight loops and the parity-even part to nine loops. We'll outline a derivation for some of the rules, illustrate their applications, compare their relative strengths for fixing coefficients, and survey some of the features of the previously unknown nine and ten loop expressions.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
