Instructor: Simon Caron-Huot, Institute for Advanced Study
Type: Perimeter Institute non-credit mini-course
Dates: September 13, 14, 17, 2010; 2:00 pm, Bob Room On-shell methods provide a powerful tool for the perturbative computation of scattering amplitudes in gauge theories, such as QCD. In these lectures I will focus on such methods which can be developed without invoking unitarity, but rather by setting one propagator by loop level on-shell ("single-cuts"). After summarizing the present status of applying these ideas to QCD, I will discuss their recent successful application to planar N=4 super Yang-Mills, leading to on-shell recursion relations for loop integrands.
