Global bases for nonplanar loop integrands, generalized unitarity, and the double copy to all loop orders
Abstract We introduce a constructive method for defining a global loop-integrand basis for scattering amplitudes, encompassing both planar and nonplanar contributions. Our approach utilizes a graph-based framework to establish a well-defined, non-redundant basis of integrands. This basis, constructe...
