Plane wave backgrounds and colour-kinematics duality
Plane wave backgrounds and colour-kinematics duality
A bstract We consider perturbative gauge theory on a fixed Yang-Mills plane wave background, describing its Feynman rules in detail. Using these rules, the tree-level 4-point gluon amplitude is computed. As an application, we investigate whether some notion of colour-kinematics duality — a relation between the colour and kinematic constituents …
