133 citations recorded by the source corpus.

This article reviews on-shell methods for analytic computation of loop amplitudes, emphasizing techniques based on unitarity cuts. Unitarity techniques are formulated generally but have been especially useful for calculating one-loop amplitudes in massless theories such as Yang–Mills theory, QCD and QED.

• The elliptic dilogarithm for the sunset graph (2013, background): “At one-loop order, around a four dimensional space-time, all the scattering amplitudes can be expanded in a basis of integral functions given by box, triangle, bubbles and tadpole integral functions, together with rational term contributions (see for [1, 2] for reviews on this subject).”
