The dimension-shift conjecture for one-loop amplitudes
Ruth Britto, Guy R. Jehu, Andrea Orta
A conjecture made by Bern, Dixon, Dunbar, and Kosower asserts a simple dimension-shifting relationship between the one-loop structure of N = 4 MHV amplitudes and all-plus helicity…

Symmetric reduction of high-multiplicity one-loop integrals and maximal cuts
Guy R. Jehu
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 kin…
