Description
We explain how to reconstruct cross-order integral relations from maximal cuts. The underlying
phenomenon is that integrals across different loop orders can have support on the same generalized
unitarity cuts and can share global poles. The technique is demonstrated for the two-loop ABDK relation
with up to five external legs. Our analysis suggests that maximal and near-maximal cuts can be used to
infer the existence of integral identities more generally.
