Gauge/string duality for weak coupling

Edward Witten

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

We review some of the unexpected simplifications of perturbative Yang–Mills theory, and motivate the idea of explaining them by using a string theory in which the target space is twistor space. Perturbative Yang– Mills scattering amplitudes arise from an instanton expansion in this string theory.
