Symmetric reduction of high-multiplicity one-loop integrals and maximal cuts
Abstract We derive useful reduction formulae which express one-loop Feynman integrals with a large number of external momenta in terms of lower-point integrals carrying easily derivable kinematic coefficients which are symmetric in the external momenta. These formulae apply for integrals with at lea...
