Spinor Helicity and Dual Conformal Symmetry in Ten Dimensions

Understand

The spinor helicity formalism in four dimensions has become a very useful tool both for understanding the structure of amplitudes and also for practical numerical computation of amplitudes.

• Recently, there has been some discussion of an extension of this formalism to higher dimensions.
• We describe a particular implementation of the spinor-helicity method in ten dimensions.
• Using this tool, we study the tree-level S-matrix of ten dimensional super Yang-Mills theory, and prove that the theory enjoys a dual conformal symmetry.
