Query: Symmetry and Action for Flavor-Kinematics Duality   We propose a new representation of the nonlinear sigma model that exhibits a
manifest duality between flavor and kinematics. The fields couple exclusively
through cubic Feynman vertices which also serve as the structure constants of
an underlying kinematic algebra. The action is invariant under a combination of
internal and spacetime symmetries whose conservation equations imply
flavor-kinematics duality, ensuring that all Feynman diagrams satisfy kinematic
Jacobi identities. Substituting flavor for kinematics, we derive a new cubic
action for the special Galileon theory. In this picture, the vanishing soft
behavior of amplitudes is a byproduct of the Weinberg soft theorem.
