Last week was the beginning of a program at the Santa Barbara KITP entitled The Harmony of Scattering Amplitudes which will focus on topics including recent advances in computing N=4 super Yang-Mills scattering amplitudes. Talks are available on-line here. There’s a full schedule of talks in the program and related talks here. On Thursday, Nima Arkani-Hamed will give a talk on “The planar integrand of N=4 super-Yang-Mills theory”, which some wag has scheduled as lasting from 1:30pm to 5am.
For a survey of some of these recent developments, a correspondent points me to the thesis of Arkani-Hamed’s student Jacob Bourjaily, which has just appeared online here.
