Abstract

We apply the differential equations technique to the calculation of the one-loop massless diagram with one off-shell leg. Using a reduction to the ϵ-form, we managed to obtain a simple onefold integral representation exact in space-time dimensionality. Expansion of the obtained result in ϵ and an analytical continuation to the physical region are discussed.
