10D Super-Yang-Mills Scattering Amplitudes From Its Pure Spinor Action

Authors: Maor Ben-Shahar and Max Guillen Preprint number: UUITP-37/21 Abstract: Using the pure spinor master action for 10D super-Yang-Mills in the gauge $b_{0}V = Q\Xi$, tree-level scattering amplitudes are calculated through the perturbiner method, and shown to match those obtained from pure spinor CFT techniques. We find kinematic numerators made of nested $b$-ghost operators, and show that the Siegel gauge condition $b_{0}V = 0$ gives rise to color-kinematics duality satisfying numerators whose Jacobi identity follows from that of a kinematic algebra.
