This meeting was organised to take stock of the rapid progress being made on twistor-string theory and to encourage further cross-fertilization between string-theory, twistor theory and perturbative gauge theory. Twistor string theory was introduced by Witten in hep-th/0312171 as a string theory in twistor space that makes contact with N=4 super Yang-Mills theory on space-time via a generalization of the Penrose-Ward transform augmented by certain D-instanton corrections. It promises to combine many of the most attractive features of string theory and twistor theory and has implications not only for Yang-Mills but also for (conformal) gravity. It has in particular led to major advances in the calculations of Yang-Mills scattering amplitudes with applications to collider physics.
