CPT Student Seminar: Calculating and Dimensionally Regularising Multi-Loop Scattering Amplitude Integrands in N=4 SYM

Presented by Tim Goddard, DurhamCPT

17 February 2014 17:00 in OC218

In the last few years there has been a departure from Feynman Integrals as the most efficient way to calculate scattering amplitudes in supersymmetric gauge theories. I will do a whiteboard talk to introduce some of the new diagrammatic methods for calculating these quantities and ask several questions such as "How easy is it to dimensionally regularise these new representations?" Then, finally, can we build these objects primarily from symmetry considerations in an algorithmic way which avoids too much effort? Pictures will be involved in more than one colour!

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