Description
One-loop integrands can be written in terms of a simple, process-independent basis. A similar basis exists for integrands of phase-space integrals for the real-emission contribution at next-to-leading order. The demonstration deploys techniques from computational algebraic geometry in order to partial-fraction integrands in a systematic way. This provides the first step towards a decomposition of phase-space integrals in a basis of master integrals.
