Color-kinematics dual representations of one-loop matrix elements in the open-superstring effective action
Abstract The α ′-expansion of string theory provides a rich set of higher-dimension operators, indexed by ζ values, which can be used to study color-kinematics duality and the double copy. These two powerful properties, actually first noticed in tree-level string amplitudes, simplify the constructio...
