Integration-by-parts reductions from unitarity cuts and algebraic geometry (1511.01071v3)
Published 3 Nov 2015 in hep-th and hep-ph
Abstract: We show that the integration-by-parts reductions of various two-loop integral topologies can be efficiently obtained by applying unitarity cuts to a specific set of subgraphs and solving associated polynomial (syzygy) equations.
