Description
Colour-kinematics duality in tree-level Yang-Mills amplitudes (BCJ relations) invites new possibilities for loop-level computations. In this talk I shall briefly introduce the generalised unitarity approach at one loop. Then, in the context of a 5-gluon, 2-loop QCD amplitude, I will demonstrate how the BCJ relations can be applied to unitarity cuts. This allows leading colour information to be recycled into nonleading colour.
