The paper “Tree-level color-kinematics duality from pure spinor actions“, co-authored by Leron Borsten (University of Hertfordshire Hatfield), Branislav Jurčo (Charles University Prague), Hyungrok Kim (Heriot-Watt), Tommaso Macrelli (ETH Zurich), Christian Saemann (Heriot-Watt), and Martin Wolf, has just been published in Physical Review D (open access, direct link here). The paper proves that the tree-level scattering amplitudes for (super) Yang-Mills theory in arbitrary dimensions and for M2-brane models exhibit color-kinematics (CK) duality.
