The box integrals in momentum-twistor geometry

Article

Abstract

An account is given of how the ‘box integrals’, as used for one-loop calculations in massless field theory, appear in momentum-twistor geometry. Particular attention is paid to the role of compact contour integration in representing the Feynman propagator in twistor space. An explicit calculation of all the box integrals, using only elementary methods, is included.
